My lady friend ran into a similar problem with fake OEM parts. She had a MIL come on for a knock sensor issue on her 08 Honda CRV. I checked it out. Sure enough, it's broken in half. I tell her to get a genuine OEM knock sensor. But she finds one on ebay at 1/4 of the cost. The packaging and part looked like the real deal. So, I installed it, and it worked until the engine got up to full operating temp, then stops reporting. When it cools down, it starts working again. I had to order another from the dealer, and it's been working fine ever since.
China is now even copying OEM packaging, so it is really getting to be impossible to tell the difference. Like how is a typical user going to tell if a spark plug is made of the right metal?
and what the hell does the customer know lmao..when you install 5 fuel pumps and cut a hole in your bed I'm sorry but that's literally the definition of insanity
After seeing the title I was getting ready to watch an 8 part series just fixing everything that had been "repaired" already. Then I remembered it was Ivan. Probably only 2 parter! Clear, concise thought process for the win! Thanks again for another interesting case study!!
When engineers make diagnostics look 'simple' like here, if customers ever get butt-hurt over the fee, they forget they're paying for the expertise and knowledge acquired over the years that _leads_ to the 'simple' diagnosis. Entertaining as always Ivan.
Every time i have seen rich AND lean codes on the same bank it is because of aftermarket garbage parts. Thanks Ivan, you made quick work of this one. Your skill and critical thinking is awe inspiring. Since there is a part 2, i assume there are more issues to be discovered?😂😂😂
The one thing about parts cannon situations.........often times whoever shot it created more problems and you end up having to sift through that before getting to the original problem.
From the title, I was thinking it was a duramax powered truck. I can't believe they had that much trouble fixing a 6.0 L. Put all the oem stuff back in and restart the diag.
Best diag man in the business. I get a kick out of watching your work your craft. I think one thing you have over the mass of diag folks is you pay attention to the data plus you understand what the data is trying to tell you. I've learned a lot from watching you diag and repair cars and trucks. You make this stuff look somewhat simple. Great work Ivan
Speaking from my experience in the automotive sector. ASE 2 year associates degree graduate specialized automotive technology class of 1995 Thaddeus Stevens College of technology. I love your work and the way you run your channel. Smart young professional mechanic in a sea of “ mechanics “
They replaced it 5 times because they don't have a clue what they are doing. And in this Generation it's a replace and guess Society... Great job Ivan 👍
The problem is the tools to diagnose properly are very expensive. I dont have a $2500 scan tool and a $200 bore scope and a $300 test lead kit and a $350 fluke. This is the main reason people chuck parts. A monkey can learn to diagnose but the barrier to entry to do it properly is too high.
I had that one diagnosed once i saw the trims after the alcohol was cleared lol. Stock L96 injectors are 50 pph and those might be 30s or even 36s lol. The map doesn't work very well when the injector is 2/3rds the size. People like that are a pain the ass haha. Its why i just fix my own stuff. Like i have a neighbor that always wants me to help him with his weird issues...but he doesn't listen and just does what he wants anyway. Sorry man.. you got this and fix it yourself if thats the case. Diagnosed his old 2000 Ford as his underdash distribution box was full of water and shorted. Replaced and the truck worked fine but said you need to find the water source and fix that. He doesn't... keeps shorting out boxes and keeps asking why... lol. I just walk away
Take the fake ones and send them back to RA. LOL Story of my life... A P71 came in the shop on the hook for no crank, no start if I can remember right, two master techs couldn't figure it out, there was 3 PCMs, Cheapo scan tools, bunch of parts. They asked me to check it out. I found the CEL wouldn't go off while cranking. So I started moving wires under dash while cranking and started up, drove the car to last master tech that gave up. I found damaged terminals in power distribution. Customer spend over $2,000 with the cannon and was spade terminal damaged for a less than $1 part.
Good find, RockAuto sent me a counterfeit set of AC Delco iridium plugs last year but were quick to correct the issue. So even the big distributors get burned!
I diagnosd a 6.6 Duramax like a week ago that had limp mode and a code for group B injector circuit, and got it running properly by just tightening the pins at the FICM and topping up the tranny fluid (they're gonna replace transmission oil cooler). When I test drove it, it was only the third V8 I've ever driven and certainly the most powerful vehicle I've ever driven and I was both happy and shitting myself at the same time.
Turns out in the quantum universe you can only assign probabilities to outcomes because on small scales things aren't actually in particular places but seem to be in many places in a kind of waveform so technically if you replaced the fuel pump on this from now till the heat death of the universe eventually it should fix the problem. Einstein said that in the context of a 30 year autistic argument he had with Neils Bohr.
fuel injectors fall under pain to get off, so get OEM. I only go for cheap when it is an easy access. Then I don't mind getting a free replacement when it fails. Although these coil overs that leave the tip in the tube are leaning towards OEM now. Digging that rubber out with a pick is a pain.
Ivan doesn't know what a "typical" problem is; he just takes the time to test and not guess. I am all for saving money; however, looking at this big picture I would say the customer should have brought the truck to Ivan to start with and could have saved $9,500. Come on, man; all of those fuel pumps?
@Anonymous-it5jw I also watch both, Eric O shows how your average local mechanic should operate whilst Ivan is a diagnostic specialist. Both are excellent at what they do.
Ok Warren🤣🤣🤣. Way to go man! I had a good car once. Got totaled in the middle of the night while I was asleep. Next one I loved. Lost that one in the 1st divorce...
Why did he replace the fuel injectors to begin with? Maybe I missed that part. Will you unmask the original problem once you get good injectors installed?
I'm 10 minutes into the video and Ivan has just read out the paperwork this sounds like it's going to be a good video, I've got every confidence that Ivan is going to knock this out of the park.
Absolutely solid diag. As always, truly enjoyed the video. I hate trying to explain to people that they can't get legit parts for THAT good of a deal. Went round and round with a customer on an F-250. He bought 8 "Motorcraft" Coils and Plugs for about $120 on EBay and wouldn't believe me that they were not Motorcraft.
I’ll have to admit, I shot the parts cannon last week on my brother’s car. It was a super intermittent stall out/fuel issue. Used bcm installed/programmed and fuel pump r&r and it was still doing it. Had a poor pin fit connection at one of the connectors. Out $250 in parts and time. Oh well.
Phone call to PHAD. Ivan: Good morning, PHAD. Caller: Hello Ivan. I'm the guy in horror flicks that chases teenagers through graveyards and swamps with a chainsaw. Is there any chance you could check out a misfire of cylinder 1 on my chainsaw? Ivan: Sure, I'm always up for a challenge.
Can't wait for part 2! Perhaps from now on whenever you get a parts cannon vehicle, have your future customers list when, where, and how much they paid for each of them to help rule out the counterfeit parts.
Most of these fake aftermarket parts are the ones that failed QC in the factory and were slated for disposal. Run into the same problem in the PC industry too, and have for years.
Parts Canon is an understatement. That received incoming parts from a whole field artillery unit of parts cannons! Nice work my friend. Can't wait for part 2. BTW Christine (Astra from Hell) is back! Guess what? He had a Flea Bay Cat put on for $69.00 I am putting a reputable Cat on today ( OEM Available) Cat cost $620.00. Want to bet it solves the cat efficiency code?
@@PineHollowAutoDiagnostics What a PITA to change. I looked at least it had a honeycomb screen on both ends. I bet it passes the drive cycle and he can get it inspected now.
One thing about getting a vehicle that’s had the parts cannon blasted at it is that it does give a relatively good idea of what isn’t wrong with it 😂. I’m not making light of the customer’s plight but as a technician I’ve received vehicles like this that I repaired relatively quickly and it wasn’t necessarily because I was so good. It was more like I had a pretty detailed record of what wasn’t wrong with it.
I’m at 23 minutes. He’s running E85. Test the alcohol content of the fuel. I’ve seen this in our rental fleet when gas was over $5. I’m excited with this diag 😊
That grinding sound was rings on cylinder because of slight hydro lock in one of the cylinders from too much fuel. Ask me why I know. Save engine by fixing before running again. Check all wires and start with new fuel after draining tank. Great video!
Ivan you are the Perry Mason of auto diagnostics! I’ll bet that the owner is totally embarrassed, lessons learned…

Have similar case few years ago. Dacia Logan with 1.4 petrol engine. Engine replaced with the same one from year newer mode. After that car run like crap. No MIL. Car was slow to accelerate, it would shake, sputter, fuel trims were crazy, throttle response was delayed. Checked everything and found few issues on the go, fix all but car was still sluggish. After few days I asked if i can see an old engine. It was gone by that time but they did give me the fuel rail with all the injectors. Behold injectors were different than the one on the car. Car was originally fitted with 8200128961 but new engine came with 8200227124. They look the same, only difference is in the number of holes where 8200128961 has 2 and 8200227124 has 4. After replacing all for injectors with 8200128961 (H274263) car run properly. ECU was not touched when engine was replaced. Trick was that in newer engine the updated FW on ECU as well so that it would work with different injectors.
This is like an epic movie... "You're our only hope Obi Wan"...But I feel for this guy. I had a similar platform truck and a 3 ring binder of service work, recalls, TSBs and parts replace, service.... Finally, got everything perfect and sold it fast.... Had no Ivan to help... This poor guy was penny wise and pound foolish...Victim of counterfeits and massive online platforms pushing the junk.
What I've noticed: You should always have a RPM and TPS pid when doing fuel trims.. There are different blocks or bands of RPM range or throttle position (depending on their strategy) that will have different fuel trims stored. So at idle vs 1/4 throttle vs 1/2 vs WOT, etc. etc.. Some vehicles will have different long term trims stored.. and that's why it's jumping around so much at first. This is why it's better to go in and reset fuel trims after fixing an issue-- rather than letting it correct itself; because if you never drive in that specific band or block- in can linger on well past a repair and not relearn correctly....... So anyway, when the long trims are jumping around like crazy-- it's easier to correlate them with a certain TPS or RPM range if you have that pid up.
Hey Ivan, Nima from CarCare here, It's always the aftermarket parts lol! Just wanted to say, I left a comment the other day saying you inspired me to start my own channel, and today I finally uploaded my first full length video. I'd appreciate any feedback. As always thanks for everything!
Agree & told my customers the same thing. Amazon & Ebay parts are Chinese knockoffs for majority of their electrical parts & even sparkplugs. They try to save a $$ and it ends up costing them a lot more in the long run. I refused to install customer supplied parts especially if they are Amazon or Ebay unless they understand & sign the statement saying they will pay my labor & I don't give any warranty on customer supplied parts & if I changed them & it doesn't fix the problem b/c of their faulty parts they will have to pay additional P&L for me to replace their defective parts with quality parts. I order OEM parts from Rock Auto time permitting with the customers approval knowing they will be quality OEM parts and a discounted price. I'm retired now & just fix some of my customers cars when they are getting faulty diagnosis repeatedly from shotgun blasts. It's nice to see you, Eric and others diagnose cars & don't throw parts at a problem. Keep the videos coming.
Dude, I have a customer (We actually grew up together) with a 2500HD that had same issues when he bought it. He is one of those people that will tell you what he wants done. I finally sent him somewhere else because I got tired of changing the parts he wanted changed. I got to the point that when he brings a vehicle and tries to tell me what he thinks is wrong, I tell him "I don't want to hear what you think is wrong Wes. I don't care what you think is wrong. I want you to tell me what the issue is and I will find out what's wrong." XD I believe he told me he finally had an ECM put in it and it cured his running probs.
I've been helping an older friend with a classic car. He can't drive and enjoy it for more than a few minutes without finding another problem. I don't think it's possible to satisfy him. And I think his memory about how it drove when new is suspect.
I had the same problem with people noitalls in my county where i lived.... They Ask you to repair or fix something and they don't even have the tools to fix it... Or I have a track machine that I use for all kinds of jobs. They open their mouth and say it can't do that. Got real kn sick of their ignorance....
All very good points. I was a mechanic for 14 years before I got the job I have now. I don't have much work done by mechanics, however, when I do, I am very careful to just give a description of the problem without giving my opinion because I don't want to "taint" the technician's thinking.
I'm an automotive locksmith and get these self diag calls all the time. I tell them programming a new fob is not going to fix their issue. I tell them when it doesn't work you are still paying me full price. I haven't had one person take me up on that. I always tell them you are just guessing and you need to pay a qualified mechanic (not me) for a proper diag. They never believe when I tell them fobs aren't like a computer and lose programming like they think. They all want "reprogramming". lol They can break and stop working but that's another issue.
Sadly, it's not even a reputable retailer situation anymore. I've received counterfeit parts from multiple Toyota, Ford and GM dealerships across North Alabama over the last couple years. I can't even begin to imagine how this happens (verified not a returned part situation), but alas, it's something to be aware of. Only a solid diagnostic process will get you where you need to go, and when it comes to working with customers, listen to everything, and believe nothing. ;)
Had a 1986 dodge B 2500 van (pre computers) always bought gas at an Exxon station by the house. 4 years of new plugs, wires, fuel pump, distributor, cap, rotor, carb, valve job ... bought gas at a different station and drove it until the roof rusted out. Their tanks leaked water. YES. I DID feel like an idiot. Still do.
I cut a access hole in my s10 blazers floor. I probably put 4 or 5 fuel pumps in it. I finally put a junkyard factory GM pump in it and it’s been all good ever since.
Only a couple minutes in and I’m betting wrong or cheap a** injectors. The body style after this one with DI is even more picky. Don’t buy cheap a** electrical parts people! And always verify part numbers. GMs official by the book “dealer” way to tell what flow rate you have for injectors is to pull them and see what part number you have. There were 4 different flow rates for the same 5.3L based on what the ecu was flashed for.
Dear comment section. Ease up a bit. Most of the total price was the replacement of the original engine which was a separate issue. Remember, it ran fine for about 3 years. They also found the problem with the CATs and O2 sensors ( is a a 2012 Chevy with a ton of miles) which, again was a separate issue. It was after that that it went down hill. It is possible that the steering angle sensor also went bad in the mean time. The blown fuses were due to a short on an O2 sensor (probably shotty installation work). It is difficult to disentangle the actual cost of wasted parts and labor on this case given the age of the vehicle and the engine swap.
Yes I did the same thing for "Bosch" injectors on my 91 Ford 460 powered motorhome. But I was lucky and and they have worked fine so far. 24K on them now.
Helped a gentleman with his gmc truck that went to 3 different chevy dealerships had a hesitation rough idle. Everytime they did/ recommend a fuel injection cleaning service. I laughed. I cleaned his MAF. Throttlebody and did a induction intake cleaning with CRC intake cleaner. Also noticed the throttle position was 30% idle after a relearn he has never had an issue. Relearning the throttle was i think the real issue. Dealership didnt clean or re-learn the throttle.
Ground issue is my guess. On to the video! :) Edit: I like to reset fuel trims when I see odd alcohol content. Just to see what it does right after. Injectors that are cheap, are usually, no almost always crap.
yep.. Good call. I was thinking either clogged injectors because they were so old.. Or it might have had a bad intake leak and was adding fuel to account for it. Either way... She needs a 7th fuel pump Ivan: obviously.. ;)
I had a 2013 with the 6.2L that I had to replace the MAF sensor on. The problem was that I installed a CAI and needed to have a sensor that could keep up with the intake. A new MAF sensor and a few trim program changes and I was golden.
It is crazy that they changed the fuel pump so many times that they cut a hole in the bed of the truck. I have seen Internet self described geniuses recommend doing this on other GM vehicles. So stupid. How about hook up a pressure gauge like you did here. That proved that the fuel pump was delivering the proper pressure.
I’m pretty sure at this point running problems I’m having with my wife’s Range Rover 5.0L engine are due to possible Fake Bosch GDI injectors purchased on EBay. Recently did a complete timing chain replacement. Install new injectors at the same time. Now engine runs very erratic. Sometimes great and then goes into over fueling big time. I have replace several of the new injectors with old injectors and the engine runs noticeably better but not smoothly as it should. I will be changing out the rest of the injectors with old known good injectors and expect good results. Fingers crossed. Just because it’s a good price doesn’t mean it’s a good part.
Would definitely check out the ground wires body to chassis? Eric O. has cured several GM trucks with ground wire problems?? Can you reset the methanol percentage to zero?
I'm a retired geezer with only minor auto repair experience... When watching Ivan I develop a thinking that his videos are required viewing for pro mechanics. That it's a way to experience COMPLICATED repairs. Are there many pro mechanics watching??
if todays techs don't watch, neither do some older mechanics. the young guys will be mentally tired as well as physically, and I can just hear the "newfangled doohickey" complaints in old guy voices just by imagining them.
I'm Semi retired. 48 years experience. ASE and GM Master and L1 drivability certified. I marvel at Ivan's Thought process and actually build the vehicle and diagnose along with him.
Well done Ivan,just finish watching part 1;I’ve had poor running problems, because a poor earth,and the earth tracks though the next easy root,but counterfeit injectors,apparently usa has a big problem,with this crap, the data does points to under fueling,look forward to part 2.
Ivan, When you were reading what the customer wrote in the first vid. I was like, HE DON'T KNOW SIR IVAN VERY WELL. HELL THAT'S WHAT YOU DEAL WITH UNUSUAL PROBLEMS BUT IN INSANE DETAIL & I'VE NEVER SEEN YOU REALLY GET FRUSTRATED. Also who gets a brand new engine & puts 400,000 Thousand mile injectors back in it ? It was a very easy fix for you, BUT YOU SIR ARE NOT THE AVERAGE DIAGNOSTIC TECH. & YOU ARE STILL YOUNG. Henry from N.E. PA.
Here’s the thing about parts cannon vehicles…..it can make diagnosing even more difficult if they bought cheap parts. I’m not even half way through and feel bad for Ivan because he’s having to untangle a complete mess which may have been easier if he saw it first. If Ivan can’t fix it, it’s demon possessed and you need to throw it in a volcano as a sacrifice.
this one is interesting i remember some time back on my 1997 gmc suburban where it would just dump fuel i happened to get lucky as i had a engine that had a oem map sensor i tried it and it was the problem however your issue is very much all over the place and not really showing this but i was wondering if it was the parts used we all have been hit by the parts plague i really hope this issue gets solved soon its such a huge problem an that is a ton of miles on injection components it’s actually incredible to be honest this customer really takes care of his truck just remember avoid the jungle website and fleebay not worth it
OK Ivan I am at eight minutes and 50 seconds into the video and I’m gonna take a stab at a faulty regulator in the fuel system, sure sounds like a pressure system problem to me, I absolutely knew it was something in the fuel system at eight minutes in,, I was suspecting bad fuel also, but I concur that these overseas parts are absolutely crap! I purchased the same scan tool last year that you use so far, I am very happy with it… still fixing cars at 69 years old
That is a fast install time. My GM injectors say to compress the o-rings for 30 minutes before installing into the fuel rail, and you only get two tubes, so you have to do it 4 times. 2 hours right there.
@@PineHollowAutoDiagnostics Ivan, the new direct injectors from about 2013 ish GM/Chevy trucks use a Teflon seal. They don't use Orings. I'm working on a 2015 GMC with the bad lifters design. I wanted to pull the fuel injectors, then I remembered if I do. I had to reseal them. The tools were cheap. So I was going to take the plunge. But I pulled both heads with the injectors.
Super Ivan to the rescue AGAIN! Customer should be paying you 10,000 for the diagnosis on his truck since nobody else could figure it out. Another parts cannon rescue complete. Nice job Ivan! And like you said you did not even have to get your hands dirty.
@ around the 23-minute mark, I suspected the injectors were the wrong type for the vehicle or engine. Broke when delivered/wrong parts are the major reason I left the auto repair business almost two years ago. I would've liked to see you perform a fuel drop test on the i njectors before calling them though.
@@PineHollowAutoDiagnostics I don't mean to argue Ivan, just spitballing thoughts. I missed where you ran drop test but in any event, having the original/ols injectors on hand, I would've swapped one to see the differential. In any event. you are a beast and I wish you continued success..
I think the problem is Ivan didn't click the seat belt. Come on Ivan, accidents can happen anytime, especially if you are distracted, such as when looking at a data minitor!
Without going past the 8:00 minute mark, I would check for missing/loose grounds. There are a ton of codes being set and that usually indicates a common fault.
Would be a waste of time without more specific direction. If there were a bunch of related "circuit" codes, then look at a wiring diagram to see if they share a common ground 👍
7:32 I would believe it about the module shorting causing problems. And the Nissan versa, a short in the right side tail/back up light caused the transmissions to malfunction. So many people were full into getting brand new transmissions when there was nothing wrong. But once they fix the short, it ran perfectly.
The imbalance in fuel trims is interesting, between bank one and bank two, are half of the injectors fakes? Can a flow test be done on the injectors to see what they actually flow?
@@PineHollowAutoDiagnostics No doubt, but your viewers love it when you break out the Pico for proof. A data driven comparison with the genuine GM injectors will condemn the Chinese junk without any room for doubt.
I guess moderator didn’t like me using the what the -- acronym. Good grief. If I installed a new engine, I think I would not have used the old 300K injectors, unless perhaps they were recently replaced before the engine replacement. I was assuming the owner did use oem , good catch Ivan. Those too good to be true prices most often are just that. 👍👍🇺🇸. ( I only used that acronym in a humorous description, that’s ok, understandable. )
If the "new" fuel injectors, etc., are simply "reprocessed" from the dud dumpster at the PRC factory on weekend midnight shifts they would still be in full harmony with ancient Confucian based commercial law norms...
yaiky, question, I don't know if you did a test on the injector or no. I looks like you when just by the price that the customer paid for them. And I would agree, too cheap to be good, but the p/n in the box looks legit. How would you test the injector to make sure they are not passing enough fuel to the engine? is there a test that you can do to see the see if these injector are passing the same amount of fuel compare to an OEM injector? I am always learning from your videos. Thank you.
For many high mileage fuel injector sets for this model year Chevy engine you can get them cleaned, rebuilt with new O-rings, and flow tested and flow matched (the flow shop usually has other used injectors to use in flow matching or if one injector is extremely off will offer to sell you a rebuilt one). If there is a bad injector coil the flow shop will let you know and you can replace the defective fuel injector.
@@PineHollowAutoDiagnostics It is possible to pay for a quick turn around on a set of injectors put this cost more money and is slower than just purchasing a set on-line with expedited shipping. So timing wise you are correct it is easier. But, if you do have enough time a flow tested and flow match a set you know the injectors don't leak (tested and cycled under pressure), have proper flow pattern, new O-rings, proper coil ohmic value and will deliver the same fuel flow optimally at between 2% and 4% (some shops even offer a within 1% option). The lowest cost scenario is with an injector type that is very popular and abundant, like the Chevy engine in your video. The more specialized the injector the more it costs to make matched sets. Fortunately, on low pressure port injectors there are many available from junked engines so many shops buy these at very low cost and rebuild, test and catalog in order to make matching sets.
This reminds me of the Chevy truck South Main Auto had where the customer installed the ebay junk and introduced more problems than it had initially
My lady friend ran into a similar problem with fake OEM parts. She had a MIL come on for a knock sensor issue on her 08 Honda CRV. I checked it out. Sure enough, it's broken in half. I tell her to get a genuine OEM knock sensor. But she finds one on ebay at 1/4 of the cost. The packaging and part looked like the real deal. So, I installed it, and it worked until the engine got up to full operating temp, then stops reporting. When it cools down, it starts working again. I had to order another from the dealer, and it's been working fine ever since.
Yes, China Fake Parts Suck and cause you extra work many times...
China is now even copying OEM packaging, so it is really getting to be impossible to tell the difference. Like how is a typical user going to tell if a spark plug is made of the right metal?
as eric o says..just because its new does not mean its good...this is one for the books
Wow! That's not parts cannon! It's a WWI Big Bertha shot! Excellent diagnostic and reasoning, Ivan! Part 2 will be very revealing!
a second truck is parked beside it. Well you said you wanted the old parts.....
@@robertsmith2956 🙂
Customer didn't know who he was dealing with when he said he didn't think you could diag his truck !!!
i was thinking the same thing! if Ivan can't figure it out all hope is lost

With all that random needless parts being chucked at it - dude now has spares for the rest of his, and his kids lifetimes! :D
The one thing about parts cannon situations.........often times whoever shot it created more problems and you end up having to sift through that before getting to the original problem.
There's probably only a handful of Ivan's videos where aftermarket junk _hasn't_ caused issues.
That bottomless bag of parts was like a fever dream. Holy cow.
From the title, I was thinking it was a duramax powered truck. I can't believe they had that much trouble fixing a 6.0 L. Put all the oem stuff back in and restart the diag.

Great job Ivan 👍
If only they had replaced it 6 times, that might have solved it. 🤣
ChatGPT told me it must be a fuel pump ... 😂

I had that one diagnosed once i saw the trims after the alcohol was cleared lol. Stock L96 injectors are 50 pph and those might be 30s or even 36s lol. The map doesn't work very well when the injector is 2/3rds the size.
People like that are a pain the ass haha. Its why i just fix my own stuff. Like i have a neighbor that always wants me to help him with his weird issues...but he doesn't listen and just does what he wants anyway.

You can lead a horse to water!!😅
Take the fake ones and send them back to RA. LOL Story of my life...
A P71 came in the shop on the hook for no crank, no start if I can remember right, two master techs couldn't figure it out, there was 3 PCMs, Cheapo scan tools, bunch of parts. They asked me to check it out. I found the CEL wouldn't go off while cranking. So I started moving wires under dash while cranking and started up, drove the car to last master tech that gave up. I found damaged terminals in power distribution. Customer spend over $2,000 with the cannon and was spade terminal damaged for a less than $1 part.
Good find, RockAuto sent me a counterfeit set of AC Delco iridium plugs last year but were quick to correct the issue.
So even the big distributors get burned!
No luck on my AC relay, they didn't even want the two bad ones back. but local parts also same bad ones. Junk yard saves the day.....
I diagnosd a 6.6 Duramax like a week ago that had limp mode and a code for group B injector circuit, and got it running properly by just tightening the pins at the FICM and topping up the tranny fluid (they're gonna replace transmission oil cooler). When I test drove it, it was only the third V8 I've ever driven and certainly the most powerful vehicle I've ever driven and I was both happy and shitting myself at the same time.
that's exactly what Ivan does with a lot of stuff.
Wasn't it Einstein that said the definition of insanity is doing the same thing over again and expecting different results?
Turns out in the quantum universe you can only assign probabilities to outcomes because on small scales things aren't actually in particular places but seem to be in many places in a kind of waveform so technically if you replaced the fuel pump on this from now till the heat death of the universe eventually it should fix the problem. Einstein said that in the context of a 30 year autistic argument he had with Neils Bohr.

fuel injectors fall under pain to get off, so get OEM. I only go for cheap when it is an easy access. Then I don't mind getting a free replacement when it fails.
Although these coil overs that leave the tip in the tube are leaning towards OEM now. Digging that rubber out with a pick is a pain.

Guy wrote that its not Ivan's typical problem, he must never have watched this channel before...
I thought the same thing
@@kerrylewis2581 I second that....
Ivan doesn't know what a "typical" problem is; he just takes the time to test and not guess. I am all for saving money; however, looking at this big picture I would say the customer should have brought the truck to Ivan to start with and could have saved $9,500. Come on, man; all of those fuel pumps?
Amen! Eric O. understands how to fix cars and trucks, but Ivan has mastered the arcane knowledge of the interplay of all automobile electronics.
@Anonymous-it5jw I also watch both, Eric O shows how your average local mechanic should operate whilst Ivan is a diagnostic specialist. Both are excellent at what they do.
$10k in parts and labor. Ouch! I've paid over $10k for only 1 car I've ever owned, and it was new. I've been driving since 1975.
What kind of car?
Ok Warren🤣🤣🤣. Way to go man! I had a good car once. Got totaled in the middle of the night while I was asleep. Next one I loved. Lost that one in the 1st divorce...
Why did he replace the fuel injectors to begin with? Maybe I missed that part. Will you unmask the original problem once you get good injectors installed?
I'm 10 minutes into the video and Ivan has just read out the paperwork this sounds like it's going to be a good video, I've got every confidence that Ivan is going to knock this out of the park.
Absolutely solid diag. As always, truly enjoyed the video. I hate trying to explain to people that they can't get legit parts for THAT good of a deal. Went round and round with a customer on an F-250. He bought 8 "Motorcraft" Coils and Plugs for about $120 on EBay and wouldn't believe me that they were not Motorcraft.
I’ll have to admit, I shot the parts cannon last week on my brother’s car. It was a super intermittent stall out/fuel issue. Used bcm installed/programmed and fuel pump r&r and it was still doing it. Had a poor pin fit connection at one of the connectors. Out $250 in parts and time. Oh well.
Phone call to PHAD.
Ivan: Good morning, PHAD.
Caller: Hello Ivan. I'm the guy in horror flicks that chases teenagers through graveyards and swamps with a chainsaw. Is there any chance you could check out a misfire of cylinder 1 on my chainsaw?
Ivan: Sure, I'm always up for a challenge.
Its hard to avoid fakes now unless u spend a mint even then you feel ripped off. That world we live in now. Its sad
Can't wait for part 2! Perhaps from now on whenever you get a parts cannon vehicle, have your future customers list when, where, and how much they paid for each of them to help rule out the counterfeit parts.
Genuine OEM parts is so important. The counterfeit parts are everywhere and sometimes reputable places resell them without knowing. Beware.
Gm owns the biggest parts company in the world, it’s a Chinese company,most of the Chinese crap is all the same junk
Those Chinese injectors ended up being the world's most expensive fuel injectors outside of the ones in cruise ships.
Trump's tariffs will solve it. They will cost $150 each when he is president. So you will buy GM's and be happy.
@@robertsmith2956The Genuine GM injectors are made in China, too, to maximize GM shareholder profit margins.
@@brassmule That is me. The spinoff companies have even better returns.
Most of these fake aftermarket parts are the ones that failed QC in the factory and were slated for disposal. Run into the same problem in the PC industry too, and have for years.
Great video, but it needs more fuel pump replacement.
Parts Canon is an understatement. That received incoming parts from a whole field artillery unit of parts cannons! Nice work my friend. Can't wait for part 2. BTW Christine (Astra from Hell) is back! Guess what? He had a Flea Bay Cat put on for $69.00 I am putting a reputable Cat on today ( OEM Available) Cat cost $620.00. Want to bet it solves the cat efficiency code?
For $69??? It's probably hollow inside xD
@@PineHollowAutoDiagnostics What a PITA to change. I looked at least it had a honeycomb screen on both ends. I bet it passes the drive cycle and he can get it inspected now.
One thing about getting a vehicle that’s had the parts cannon blasted at it is that it does give a relatively good idea of what isn’t wrong with it 😂.
I’m not making light of the customer’s plight but as a technician I’ve received vehicles like this that I repaired relatively quickly and it wasn’t necessarily because I was so good. It was more like I had a pretty detailed record of what wasn’t wrong with it.
Saw you on SMA. im going back 8 years to watch SMA vids so i icame here for newer vids.

That grinding sound was rings on cylinder because of slight hydro lock in one of the cylinders from too much fuel. Ask me why I know. Save engine by fixing before running again. Check all wires and start with new fuel after draining tank. Great video!

@@ryans413 too bad they cut a hole in the bed 😂
Ivan you are the Perry Mason of auto diagnostics! I’ll bet that the owner is totally embarrassed, lessons learned…
Have similar case few years ago. Dacia Logan with 1.4 petrol engine. Engine replaced with the same one from year newer mode. After that car run like crap. No MIL. Car was slow to accelerate, it would shake, sputter, fuel trims were crazy, throttle response was delayed. Checked everything and found few issues on the go, fix all but car was still sluggish. After few days I asked if i can see an old engine. It was gone by that time but they did give me the fuel rail with all the injectors. Behold injectors were different than the one on the car. Car was originally fitted with 8200128961 but new engine came with 8200227124. They look the same, only difference is in the number of holes where 8200128961 has 2 and 8200227124 has 4. After replacing all for injectors with 8200128961 (H274263) car run properly. ECU was not touched when engine was replaced. Trick was that in newer engine the updated FW on ECU as well so that it would work with different injectors.
This is like an epic movie... "You're our only hope Obi Wan"...But I feel for this guy. I had a similar platform truck and a 3 ring binder of service work, recalls, TSBs and parts replace, service.... Finally, got everything perfect and sold it fast.... Had no Ivan to help... This poor guy was penny wise and pound foolish...Victim of counterfeits and massive online platforms pushing the junk.
What I've noticed: You should always have a RPM and TPS pid when doing fuel trims.. There are different blocks or bands of RPM range or throttle position (depending on their strategy) that will have different fuel trims stored. So at idle vs 1/4 throttle vs 1/2 vs WOT, etc. etc.. Some vehicles will have different long term trims stored.. and that's why it's jumping around so much at first. This is why it's better to go in and reset fuel trims after fixing an issue-- rather than letting it correct itself; because if you never drive in that specific band or block- in can linger on well past a repair and not relearn correctly....... So anyway, when the long trims are jumping around like crazy-- it's easier to correlate them with a certain TPS or RPM range if you have that pid up.
Hey Ivan, Nima from CarCare here, It's always the aftermarket parts lol! Just wanted to say, I left a comment the other day saying you inspired me to start my own channel, and today I finally uploaded my first full length video. I'd appreciate any feedback. As always thanks for everything!
Great 😂
welcome to the diag team.
Good luck
Agree & told my customers the same thing. Amazon & Ebay parts are Chinese knockoffs for majority of their electrical parts & even sparkplugs. They try to save a $$ and it ends up costing them a lot more in the long run. I refused to install customer supplied parts especially if they are Amazon or Ebay unless they understand & sign the statement saying they will pay my labor & I don't give any warranty on customer supplied parts & if I changed them & it doesn't fix the problem b/c of their faulty parts they will have to pay additional P&L for me to replace their defective parts with quality parts. I order OEM parts from Rock Auto time permitting with the customers approval knowing they will be quality OEM parts and a discounted price. I'm retired now & just fix some of my customers cars when they are getting faulty diagnosis repeatedly from shotgun blasts. It's nice to see you, Eric and others diagnose cars & don't throw parts at a problem. Keep the videos coming.
Dude, I have a customer (We actually grew up together) with a 2500HD that had same issues when he bought it. He is one of those people that will tell you what he wants done. I finally sent him somewhere else because I got tired of changing the parts he wanted changed. I got to the point that when he brings a vehicle and tries to tell me what he thinks is wrong, I tell him "I don't want to hear what you think is wrong Wes. I don't care what you think is wrong. I want you to tell me what the issue is and I will find out what's wrong." XD I believe he told me he finally had an ECM put in it and it cured his running probs.
I've been helping an older friend with a classic car. He can't drive and enjoy it for more than a few minutes without finding another problem. I don't think it's possible to satisfy him. And I think his memory about how it drove when new is suspect.
Ooo
I had the same problem with people noitalls in my county where i lived.... They Ask you to repair or fix something and they don't even have the tools to fix it... Or I have a track machine that I use for all kinds of jobs. They open their mouth and say it can't do that. Got real kn sick of their ignorance....
All very good points. I was a mechanic for 14 years before I got the job I have now. I don't have much work done by mechanics, however, when I do, I am very careful to just give a description of the problem without giving my opinion because I don't want to "taint" the technician's thinking.
I'm an automotive locksmith and get these self diag calls all the time. I tell them programming a new fob is not going to fix their issue. I tell them when it doesn't work you are still paying me full price. I haven't had one person take me up on that. I always tell them you are just guessing and you need to pay a qualified mechanic (not me) for a proper diag. They never believe when I tell them fobs aren't like a computer and lose programming like they think. They all want "reprogramming". lol They can break and stop working but that's another issue.
Sadly, it's not even a reputable retailer situation anymore. I've received counterfeit parts from multiple Toyota, Ford and GM dealerships across North Alabama over the last couple years. I can't even begin to imagine how this happens (verified not a returned part situation), but alas, it's something to be aware of. Only a solid diagnostic process will get you where you need to go, and when it comes to working with customers, listen to everything, and believe nothing. ;)
Had a 1986 dodge B 2500 van (pre computers) always bought gas at an Exxon station by the house. 4 years of new plugs, wires, fuel pump, distributor, cap, rotor, carb, valve job ... bought gas at a different station and drove it until the roof rusted out. Their tanks leaked water. YES. I DID feel like an idiot. Still do.
Ivan my thoughts are non-factory fuel injectors. Possible flow issues?
I cut a access hole in my s10 blazers floor. I probably put 4 or 5 fuel pumps in it. I finally put a junkyard factory GM pump in it and it’s been all good ever since.
Only a couple minutes in and I’m betting wrong or cheap a** injectors. The body style after this one with DI is even more picky. Don’t buy cheap a** electrical parts people! And always verify part numbers. GMs official by the book “dealer” way to tell what flow rate you have for injectors is to pull them and see what part number you have. There were 4 different flow rates for the same 5.3L based on what the ecu was flashed for.
Dear comment section. Ease up a bit. Most of the total price was the replacement of the original engine which was a separate issue. Remember, it ran fine for about 3 years. They also found the problem with the CATs and O2 sensors ( is a a 2012 Chevy with a ton of miles) which, again was a separate issue. It was after that that it went down hill. It is possible that the steering angle sensor also went bad in the mean time. The blown fuses were due to a short on an O2 sensor (probably shotty installation work).
It is difficult to disentangle the actual cost of wasted parts and labor on this case given the age of the vehicle and the engine swap.
I'm guessing that original engine ran like garbage due to clogged cats 😂
@@PineHollowAutoDiagnostics Don't you put that evil on me Ricky Bobby! Surely not😳😳
Great video Ivan! Buyer beware! You’ve saved all of us so much money!! Thank you!!😅
Yes I did the same thing for "Bosch" injectors on my 91 Ford 460 powered motorhome. But I was lucky and and they have worked fine so far. 24K on them now.
Helped a gentleman with his gmc truck that went to 3 different chevy dealerships had a hesitation rough idle. Everytime they did/ recommend a fuel injection cleaning service. I laughed. I cleaned his MAF. Throttlebody and did a induction intake cleaning with CRC intake cleaner. Also noticed the throttle position was 30% idle after a relearn he has never had an issue. Relearning the throttle was i think the real issue. Dealership didnt clean or re-learn the throttle.
@@meanodustino9563 huh I never had to do a "throttle relearn" on any GM... Didn't even know that was an option 😅
Ground issue is my guess.
On to the video! :)
Edit: I like to reset fuel trims when I see odd alcohol content. Just to see what it does right after.
Injectors that are cheap, are usually, no almost always crap.
Had a reman engine installed in my 2001 Durango just so i could continue driving some i was able to work on plus i like it.
Have you ever sent a set of original injectors out to be cleaned and flow tested? Great job on your presentation's. I enjoy them very much.
7:19 steering angle sensor codes- related to 5v circuit from PCM. I’m now betting on a grounding blue or tan 5v wire.
yep.. Good call. I was thinking either clogged injectors because they were so old.. Or it might have had a bad intake leak and was adding fuel to account for it. Either way... She needs a 7th fuel pump Ivan: obviously.. ;)
I thought the hot restart issue was going to be those red china coils all going open when hot 😂
I had a 2013 with the 6.2L that I had to replace the MAF sensor on. The problem was that I installed a CAI and needed to have a sensor that could keep up with the intake. A new MAF sensor and a few trim program changes and I was golden.
I guess buy now and pay later isn't just for some kind of credit stuff.
Nice thought process with diagnosing that truck.
It is crazy that they changed the fuel pump so many times that they cut a hole in the bed of the truck. I have seen Internet self described geniuses recommend doing this on other GM vehicles. So stupid.
How about hook up a pressure gauge like you did here. That proved that the fuel pump was delivering the proper pressure.
I’m pretty sure at this point running problems I’m having with my wife’s Range Rover 5.0L engine are due to possible Fake Bosch GDI injectors purchased on EBay. Recently did a complete timing chain replacement. Install new injectors at the same time. Now engine runs very erratic. Sometimes great and then goes into over fueling big time. I have replace several of the new injectors with old injectors and the engine runs noticeably better but not smoothly as it should. I will be changing out the rest of the injectors with old known good injectors and expect good results. Fingers crossed. Just because it’s a good price doesn’t mean it’s a good part.
There's no day I watch Ivan's content and I don't learn something new❤
All i can say about cheap parts , is the auto
Makers get their parts from ebay too !
They are also imported !
What a beautiful catalog. Great description, cheers.
Would definitely check out the ground wires body to chassis? Eric O. has cured several GM trucks with ground wire problems?? Can you reset the methanol percentage to zero?
I had an s10 basically my story, i put a block on the pedal and sent it off a cliff after a 14k loss. I paid up for my spider injection
I'm a retired geezer with only minor auto repair experience... When watching Ivan I develop a thinking that his videos are required viewing for pro mechanics. That it's a way to experience COMPLICATED repairs. Are there many pro mechanics watching??
if todays techs don't watch, neither do some older mechanics. the young guys will be mentally tired as well as physically, and I can just hear the "newfangled doohickey" complaints in old guy voices just by imagining them.
I’ve been a diesel tech for 36 years. I love watching Ivan show how it gets done with real diagnostic data. Parts cannon is never the answer.
Yep
I'm Semi retired. 48 years experience. ASE and GM Master and L1 drivability certified. I marvel at Ivan's Thought process and actually build the vehicle and diagnose along with him.
I understand there are many technicians that watch Ivan. Heck, there are even other TH-camrs that watch Ivan; maybe even Eric O. with SMA. LOL!
Another great Ivan diagnosis! Rock Auto is a good place to shop? I think so, from my limited experiences.
Well done Ivan,just finish watching part 1;I’ve had poor running problems, because a poor earth,and the earth tracks though the next easy root,but counterfeit injectors,apparently usa has a big problem,with this crap, the data does points to under fueling,look forward to part 2.
I trust what you say, OEM only. You have shown this so many times. Aftermarket parts are the third rail of auto repair. You will get burned. lol
Ivan, When you were reading what the customer wrote in the first vid. I was like, HE DON'T KNOW SIR IVAN VERY WELL. HELL THAT'S WHAT YOU DEAL WITH UNUSUAL PROBLEMS BUT IN INSANE DETAIL & I'VE NEVER SEEN YOU REALLY GET FRUSTRATED.
Also who gets a brand new engine & puts 400,000 Thousand mile injectors back in it ? It was a very easy fix for you, BUT YOU SIR ARE NOT THE AVERAGE DIAGNOSTIC TECH. & YOU ARE STILL YOUNG.
Henry from N.E. PA.
Here’s the thing about parts cannon vehicles…..it can make diagnosing even more difficult if they bought cheap parts. I’m not even half way through and feel bad for Ivan because he’s having to untangle a complete mess which may have been easier if he saw it first. If Ivan can’t fix it, it’s demon possessed and you need to throw it in a volcano as a sacrifice.
this one is interesting i remember some time back on my 1997 gmc suburban where it would just dump fuel i happened to get lucky as i had a engine that had a oem map sensor i tried it and it was the problem however your issue is very much all over the place and not really showing this but i was wondering if it was the parts used we all have been hit by the parts plague i really hope this issue gets solved soon its such a huge problem an that is a ton of miles on injection components it’s actually incredible to be honest this customer really takes care of his truck just remember avoid the jungle website and fleebay not worth it
When you find yourself a good mechanic you've hit the lottery.
OK Ivan I am at eight minutes and 50 seconds into the video and I’m gonna take a stab at a faulty regulator in the fuel system, sure sounds like a pressure system problem to me, I absolutely knew it was something in the fuel system at eight minutes in,, I was suspecting bad fuel also, but I concur that these overseas parts are absolutely crap! I purchased the same scan tool last year that you use so far, I am very happy with it… still fixing cars at 69 years old
That is a fast install time. My GM injectors say to compress the o-rings for 30 minutes before installing into the fuel rail, and you only get two tubes, so you have to do it 4 times. 2 hours right there.
Never heard of compressing orings 😅
@@PineHollowAutoDiagnostics
Ivan, the new direct injectors from about 2013 ish GM/Chevy trucks use a Teflon seal.
They don't use Orings.
I'm working on a 2015 GMC with the bad lifters design.
I wanted to pull the fuel injectors, then I remembered if I do. I had to reseal them.
The tools were cheap. So I was going to take the plunge. But I pulled both heads with the injectors.
The owner = "Oh ye of little faith" in Ivan!
Super Ivan to the rescue AGAIN! Customer should be paying you 10,000 for the diagnosis on his truck since nobody else could figure it out. Another parts cannon rescue complete. Nice job Ivan! And like you said you did not even have to get your hands dirty.
P.R.C strikes again.
@ around the 23-minute mark, I suspected the injectors were the wrong type for the vehicle or engine. Broke when delivered/wrong parts are the major reason I left the auto repair business almost two years ago. I would've liked to see you perform a fuel drop test on the i njectors before calling them though.
What would the fuel drop test show? 🤔
@@PineHollowAutoDiagnostics Just a thought about improper/uneven injector psi drops.
@@tinkerwest need a known-good injector to compare the flow...here all 8 had insufficient flow, but they were all the same 😉
@@PineHollowAutoDiagnostics I don't mean to argue Ivan, just spitballing thoughts. I missed where you ran drop test but in any event, having the original/ols injectors on hand, I would've swapped one to see the differential. In any event. you are a beast and I wish you continued success..
I think the problem is Ivan didn't click the seat belt. Come on Ivan, accidents can happen anytime, especially if you are distracted, such as when looking at a data minitor!
Without going past the 8:00 minute mark, I would check for missing/loose grounds. There are a ton of codes being set and that usually indicates a common fault.
Would be a waste of time without more specific direction. If there were a bunch of related "circuit" codes, then look at a wiring diagram to see if they share a common ground 👍
I've seen a stop light switch back feed power into a gm truck making it act like it was demonically possessed 😂
Nice diagnosis!!!! Thanks Ivan!
GM/AC Delco injectors are $35/ea on Rockauto, which is a supplier we trust.
7:32 I would believe it about the module shorting causing problems. And the Nissan versa, a short in the right side tail/back up light caused the transmissions to malfunction. So many people were full into getting brand new transmissions when there was nothing wrong. But once they fix the short, it ran perfectly.
I love RockAuto I don't do a ton of repairs but I've never had an issue in the 10 years or whatever I've been using them.
The imbalance in fuel trims is interesting, between bank one and bank two, are half of the injectors fakes? Can a flow test be done on the injectors to see what they actually flow?
No sense in doing that since all the injectors are Chinese knock offs 😅
More likely the poor manufacturer quality is making them all inject different amounts of fuel.
@@PineHollowAutoDiagnostics No doubt, but your viewers love it when you break out the Pico for proof. A data driven comparison with the genuine GM injectors will condemn the Chinese junk without any room for doubt.
Can't remember how many times we've heard, Ivan your my last hope..
The parts cannon on this was going nuclear 🔥 HOT...
I guess moderator didn’t like me using the what the -- acronym. Good grief. If I installed a new engine, I think I would not have used the old 300K injectors, unless perhaps they were recently replaced before the engine replacement. I was assuming the owner did use oem , good catch Ivan. Those too good to be true prices most often are just that. 👍👍🇺🇸. ( I only used that acronym in a humorous description, that’s ok, understandable. )
If the "new" fuel injectors, etc., are simply "reprocessed" from the dud dumpster at the PRC factory on weekend midnight shifts they would still be in full harmony with ancient Confucian based commercial law norms...
I have run into part problems on average one a month for the last few years. I am a little shop and don't do a high volume of cars.
Good video Ivan. Rock Auto was awfully low, can they be trusted?
yaiky, question, I don't know if you did a test on the injector or no. I looks like you when just by the price that the customer paid for them. And I would agree, too cheap to be good, but the p/n in the box looks legit. How would you test the injector to make sure they are not passing enough fuel to the engine? is there a test that you can do to see the see if these injector are passing the same amount of fuel compare to an OEM injector? I am always learning from your videos. Thank you.
Need a known-good injector to compare flow rates. No need in this case, since that was the ONLY possible cause for the severe lean condition :)
@@PineHollowAutoDiagnostics Thanks for the reply
For many high mileage fuel injector sets for this model year Chevy engine you can get them cleaned, rebuilt with new O-rings, and flow tested and flow matched (the flow shop usually has other used injectors to use in flow matching or if one injector is extremely off will offer to sell you a rebuilt one). If there is a bad injector coil the flow shop will let you know and you can replace the defective fuel injector.
@@windward2818 easier to just buy a set of new OEM injectors 😄
@@PineHollowAutoDiagnostics It is possible to pay for a quick turn around on a set of injectors put this cost more money and is slower than just purchasing a set on-line with expedited shipping.
So timing wise you are correct it is easier.
But, if you do have enough time a flow tested and flow match a set you know the injectors don't leak (tested and cycled under pressure), have proper flow pattern, new O-rings, proper coil ohmic value and will deliver the same fuel flow optimally at between 2% and 4% (some shops even offer a within 1% option). The lowest cost scenario is with an injector type that is very popular and abundant, like the Chevy engine in your video. The more specialized the injector the more it costs to make matched sets. Fortunately, on low pressure port injectors there are many available from junked engines so many shops buy these at very low cost and rebuild, test and catalog in order to make matching sets.
