- Time for another ROAD TRIP...
This time we're headed East towards Staten Island, NYC!
First stop along the way is at a "junkyard garage" near Lewistown, PA.
This 2002 GMC Sonoma V6 has been BOMBARDED with the junkyard parts cannon for a long crank and low power complaint. They changed the fuel pump 5 TIMES!!
Let's see if we can figure out why this poor truck is falling on its face...

It seems incredible to me that you need to travel from PA to NY to find a twisted fuel line. The level of incompetence in this country is amazing and is growing by the day.
My dad was a radio operator in the Korean war, and a I sat in the basement for years watching him fix tvs and radios other shops took the "shotgun" method to, and still couldn't get them right. And he'd always tell the person "awe, just give me 10 bucks." I'm not sure about him, but the satisfaction of seeing fix stuff others couldn't was worth a million dollars to me. Especially when it's your hero who does it.
Back in the day I encountered a nearly new Class A motorhome with a 454 Chev. The builder routed the suction line from the tank to the mechanical pump in an awkward way that caused a kink in the 3/8 rubber line. It wasn't that bad but I was very suspicious and cut that kinked section out and opened up the line at the kink. To everyone's amazement there was a chunk of rubber from the manufacturing process that was stuck right at the kink. The poor people had been sitting at the side of the road many times and the motorhome spent many visits at a big Chev dealership. It had at least 4 fuel pumps. Needless to say the owner was very happy it was fixed and was not happy that a small shop in the middle of nowhere fixed something a big dealer couldn't.
They don't call them "stealers" for nothing!
Once you zTHz
Once you Tz
Once you THINK you are the EXPERT , big bad dealer technician , you are not thinking straight . Unless you test your way through the problem , you are missing something . Basics FIRST .
I’ve lost all hope for humanity. They replaced the fuel pump FIVE TIMES??? Why? Plus they and this guy spent hours checking diagnostics with a $5,000 computer, yet no one thought to check the most obvious basic things? Once you’ve replaced one fuel pump and you’ve still got a fuel delivery issue, something is obviously blocked!! Guess what, it’s time to perform the visual inspection that should have been done BEFORE the original pump was taken off.
It’s this type of laziness that made it possible for the powers that shouldn’t be to get away with the last two years of nonsense. Not only has no one got any basic mechanic skills anymore, but no common sense either. Darwin has a plan for y’all.
5 fuel pumps! That's not a parts cannon. That's a parts gatling gun!
Sub machine gun..
The revolver!
Parts bukkake!
Parts drone dropping carpet bombs
😂😂😂
I own a 97 GMC 1500 with a 4.3, and I can tell you, those spiders with the poppet injectors are very fuel pressure sensitive. They won't open below somewhere around 50 psi. When it did a start stall and the pressure dipped... It was like "ding ding ding... Problem is there" immediately. Great job Ivan. Parts cannons need not apply.
And this is the difference between a mechanic and a parts exchanger. Ivan and someone like Wes will spend a ton of time making sure they fully understand the problem before ever picking up a wrench. Thoroughness counts.
Most shops won't give the guys enough time to correctly diagnose the problems. They want the car in and out as quick as possible. The guy who sits back and tries to think is seen as lazy and stupid while the guy that goes in full bore parts cannon mode is seen as a 'real go getter'.
You have to wonder about the behind the scenes reactions when a mech throws in parts for weeks and the tech comes in and fixes it in minutes without parts then tells them to put all the old parts back in.
I can see what keeps guys like Ivan going.
Very cool! Early on I was thinking clogged fuel filter. Finding that twisted/kinked fuel line was amazing.
Bit of a spoiler this lol
I had a big Olds that did this after I'd run the fuel tank down to vapours. Fuel filter was full of sand.
Ivan, should have told these guys to find out who was last person to touch that fuel line. that was yumans fault!
There was one a while ago on a different channel., They found a shop towel in the fuel tank, that would float on the fuel, but as the fuel got used up it would settle on the fuel pump inlet.
The push button is the best deterrent there is. I bought a car where the previous owner put a button in the starter circuit. You had to simply hold in the button while starting. You would be surprised how many people just had so much trouble starting the car even when I told them what to do.
Another outstanding video. Love that you'll verbally explain the thought process and escalate the procedure as necessary.
A few years ago I was following a channel where this older
man got a real good deal on an 2nd hand motorhome. At
first all was well but then it lost power. He found a pretty
good shade tree mech who changed the fuel pump. That
helped for awhile BUT the problem returned. The mech
figgered the pump defective & replaced it again. OK
for awhile but the problem returned. The mech replaced
the pump about 2 more times before the old guy fired him.
One day a man & his son contacted this motorhome
owner. They were both career mechs & took a look.
They suspected the cat. So, they hacksawed the cat off &
took it for a ride & 200mi later STILL OK. So they put in
a new cat and everyone lived happily ever after.
!
At the point in the video when it took 5+ key cycles to get the fuel pressure to come up, my first thought was that something must be restricting the fuel flow. Maybe clogged fuel filter? But then Ivan found a kink in the fuel line right after the filter. There was that AH HA moment. lol. Nice work Ivan!
Holy hydrocarbons, Batman ... Id never change a fuel pump more than four times
"No one cares..."
One of my favorite quotes when reading pids.
I guess I understand the previous mechanic's frustration. I changed a good alternator twice before I settled down and found the real problem. The Pico waveforms really highlight your comments in the bonus footage. That truck could really use parts that perform as the designers intended. Great video! Thanks for Sharing!
As soon as I saw the fuel pressure take so long to build, but that it actually did achieve decent pressure, that signaled flow issue to me. What I didn’t guess right was a restriction. I thought they had a leak in that short run of hose from the actual pump outlet to the metal output tube. Great job, Ivan!!
I thought for sure it was going to be a restricted fuel filter.
@@davidsine4390 that was my guess. I've seen similar from the fuel filter before.
First thing I thought when I saw the initial symptoms - plugged fuel filter or obstructed line. I understand that for purposes of the video and as a professional mechanic you need to stick to the process by eliminating other possibilities, but if I were working on my own car, and knew the pump had been changed multiple times, the first thing I'd have done was a visual inspection of the fuel line. This was a case where a knowledgeable layperson could have fixed it quickly. BTW, thanks for helping to make laypeople more knowledgeable about their cars.
That's crazy! At what point does common sense or logic kick in to tell you that maybe after 5 fuel pumps it's time to take another direction. The way these shops operate is scary
After the second fuel pump it's time to take another direction!
@@johnaclark1 I agree... or just diagnose it properly 😫😁
like another guy mentioned they have been using used parts
I'll give them half credit for being on the right track.

Ivan, I still think they should change the fuel pump a few more times. They've gotten into a routine. Why change it now?
LOL you have to wonder...at what point do you start doing something *other* than just changing the fuel pump repeatedly? I shudder to think how they are "fixing" other cars with that kind of logic train.
Best do it every time they fill tank 😅😅😅
Ivan ,after the second pump you'd think that shop would say "Hang about, have we got something else going on ? " You are a young man compared to me, but you think and diagnose old school, You are welcome in our shop any time 🥰
Why am I still smh over the never ending dumbness of backyard hacks? The warning signs were right there the moment you opened the drivers door and those two hacked push buttons appeared on the dash. You have far more patience and tolerance than me. Kudos.👍
When you first put the fuel pressure gauge on, it climbed so slowly.
After the twist was removed, it shot right up there!
Great find!
I noticed on my Marquis that I was experiencing an extended crank time. This car has always started right up with no hesitation. The fuel pressure was low. 1 new OEM fuel pump later and she starts and runs like new. The car only had 410,000 miles. I guess they don't make fuel pumps like the used to.....Great video!!
Wow. Thought my Crown Vic was doing great with 301,000 miles. Fantastic.
@@gregwhite5058 I appreciate the comment, however, mine is a 1996 LS. it is 27 years old. So, what is that about 18,000 miles per year? That is just barely average mileage. I would bet yours is much newer.
@@lvsqcsl Nope, mine's an 86 so it's even lower miles/year. What I was referring to was that very few people maintain their cars well enough to go that number of miles regardless of how many miles per year. Plus, I don't think they're built as well now as they were back then.
@@gregwhite5058 I actually traded an '87 Coupe for this car. It had over 120,000 miles when I traded it. I had bought it new and I also bought the '96 new. There is no question cars were built better then.
This hits extremely close to home for me as a professional mechanic we were always known as the go to independent shop in our area when no one else could fix it the car arrived at our door, got very comical after a while to see what some of the hacks would do to make an attempt to repair things! Keep up the good work, Ivan, I love to watch your videos and try to guess the outcome. All the while I was thinking, clogged fuel filter or possibly the pressure regulator, which is located under the intake.
Hah this one was fun 😅
there is nothing quite as satisfying , as fixing a job that has done the rounds.
I can’t believe I’m going to confess…this was exciting to watch!
Awesome fix Ivan! Love these trips you take!
great find. It's always a good feeling to locate a problem no one else found.
That was awesome. A complicated problem with a simple fix nobody bothered to check.
Great diagnosis Ivan, tutorial for the rest 👌
Thanks for sharing
Once again you find the issue Ivan !!! Your good at what you do. Always a pleasure following along your diagnosing a problem.
Very cool Ivan! It’s amazing how things are diagnosed in the shop. Sometimes the service writer will even make a call on a fuel pump before the mechanic even looks at it.
This is a great video with explanations of Ivan's thought process. Very informative and enjoyable. That new style pressure sensor works like a champ. Thanks, Ivan!
Precision at its best. Well done.
Great video Ivan! A lot to learn from this one! Thank you for sharing!
Outstanding work and hats off to u working in the cold
Fuel pressure gauge for the win!
Good one Ivan, you got it!
You are the best. I would not have imagine you couldn’t get an idle with a little low pressure
You are the Man !!! Love your work.
Not surprising to see something twisted up like that from an Auto Wrecker!!! Good job catching that!!
All the best from Canada
That was a very cool find, kinked fuel line. Thanks Ivan!
Another great video! I was thinking it was a fuel restriction problem but I’m not really familiar with these systems but man you mailed that one as always! Visual inspections win most of the weirdest problems.
Keep up the great work Ivan! I had a lady change a fuel pump on a very nice 95 eagle talon and she did the same thing twisted the crap out of the hose lol I made her fix it because she was new to working on cars and I didn’t want to take the wind out of her sails lol 😂
That was me at age 17 wrecking perfectly running cars. There is power in experience. Experience comes with constantly sticking your nose in there and remembering your mistakes. Hopefully your customer sees this and wont miss any more twisted hoses right under their noses the rest of their lives. (Coulda been the person before..not saying your customer did that)
That was a FANTASTIC Find! Well Done!!
Every day's a school day! Especially when you have access to such amazing learning tools for free. Cheers Ivan! 👍
Something is restricting fuel delivery is my thought. Then you confirmed it. Love learning from a master Ivan. We are lucky to watch you paint your masterpieces.
I'm happy to see this is a problem I could have figured out without all the high dollar test equipment. There is still hope for the shade tree mechanic!
Thanks Ivan!
Ur more fun than watching the detective diaries, always something everbody else overlooks, ur logical approach leads u to the find and fix, as long as other mechanics don’t follow ur approach u will always have work, ur the best!
Nice job Ivan!
Great troubleshooting skillz 👍👍💗
Congratulations! I have never guessed correctly. I was thinking about low voltage at the fuel pump.
Great Job as usual!
Great diagnosis Ivan!
WOW! Real diagnosis, Rare
Basics first, nothing like old school technique with visual inspection,boy you travel all over, good job
another example of truly great diagnostic work Ivan!! I had a similar situation with a 2000 chevy s10 blazer.( I had previously done spider injectors on the truck a few months prior to this problem).the truck would not restart when hot and it was flooding the cylinders and the oil smelled like gas.hooked a pressure gauge to it and it was idling with a fuel pressure of 85 psi! I had recently done the injectors and regulator for this truck and used OE parts so I didn't suspect them yet. but when the owner told me this started happening after he replaced the fuel pump I went the the lines at the pump and bingo,I found a kinked return line!straightened it out and it ran great and started every time hot or cold!!
As always creative, thank you
Excellent diagnoses. That "spider" style fuel injection was extrememly sensitive to fuel pressure.
Honestly, this are goooood diagnostic.
Thank you so much for this video! I have 2 Jimmy's around the same year and one of them is having a fuel problem that I have been struggling to figure out. Guy I bought it off of just changed the fuel pump and filter, I was getting a similar fuel pressure to what you are seeing there. Going to go through all the lines now!!
Strong work! great job !
Not very usual problem , great diag 👍🏻
You did a great job Ivan
It is very easy to kink a spider injector line when installing the injector set. I did it and it resulted in a single cylinder misfire. The good thing is it did not break. Great video. Thumbs up
@Pine Hollow Auto Diagnostics St. Ivan, the savior of motors!
Ivan you are the man once again!!!!!
Great troubleshooting
Nice work Ivan.
Wow, kinked fuel line!! No wonder the sonoma ran crap. Even ran at all. Dang! Great find and diagnosis!!! I got a slight problem, my 4.3 v6 hesitates sometimes when it's cold. Trying to not to throw parts at it. But trying to think of things to look. Engine runs perfect when hot. Great video btw!!
Sweet diagnosis Ivan. So bizarre that the fuel line was that twisted. Great vid. Thankjs for sharing !!
Yeah.... wanna give somebody a bad day? Twist their gas line tight.... eeeeow ...
I'm not surprised.
I've a LOT a butchery in my day...
Excellent job. I really enjoy your content. Cheers
Nice job. Those trucks are known for wiring shorts in the wiring harness going over the back of the engine that is mostly related to starting issues, hence installed start button.
That was a great diagnosis video.
When you finally got it running right you should have said “Whoa - Chevy thunder!”
The car doctor won again man myfriend you are dam good buddy godbless and stay safe
The factory OEM clamp for the distributor will allow 7 degrees of adjustment each way.
You can buy a SB 350 hold down clamp then it will allow you to turn it more..... or replace the distributor. Common issue for that distributor gear to wear in high mileage engines. Good job on the fuel pump diagnose!
Awesome Job and Troubleshooting.
Couldn’t remember if I watched this one or not before but this was a very satisfying video to say the least!
5 FUEL PUMPS BRO! 😂😆
Great video again by PHAD
Nice diagnosis!
Nice diag my friend. We think alike. I went right to fuel delivery about the same time you did.
Such a good video, Ivan!
Nice work!
Ivan thanks for sharing nice find. I guess the scope parameters remained bad even though you got it to run. 👍
Good catch!
Those are the hardest things to catch. I prefer smoke. At least I know what went bad and where it is at.
Wow, that was really cool.
Damn u have a tuque and a jacket on unreal
It’s freaking 102 here in Dallas tx today!!!
Hey u want to switch places? Ha ha 😅
Nice work brother.
Great going Ivan! That was really offbeat and in addition, hidden from view. Reminds me of that Hyundai with the fractured camshaft dowel pin.
Love the Verus pro. I now have two of them. Because of them being wireless
There's OEM junkyard and aftermarket junkyard and as always the OEM variety wins the day. Nice fix and 1st success on the journey to the greatest diagnostic show on earth, Staten Island. Any tech worth his salt has to make that rendezvous. The Olympics of the tech world. When are they presenting the gold,silver and bronze?
what many people forget is that pressure alone isn't everything. you can have lotsa pressure but little to none actual Flow. Such conditions can even cost lives in fire fighting
Amazing you found the kink in the line, even more amazing how it affected the truck. Whoever put that fuel filter on shouldn't be around vehicles.
Great job
back in the 1970 s 80 s i had a uk hillman avenger in the usa they called them a plymouth cricket the factory coated in side the fuel tank and it peeled and clogged lines and filters gave symptoms the same as you had good catch finding that pipe
Ivan fixed it again!
You don't have to convince me (or any other Jeep mechanic) about the absolute need to replace OEM with OEM especially when it comes to the electrical components! 90% of the time my '98 TJ will NOT run smoothly when after market components are installed. I have a cash'e of OEM new sensors that I picked up here and there on Ebay, Amazon, etc..... so I won't be hung out to dry should the current ones fail. Great work at finding the twist in that fuel line, Ivan! 👍
Good job!!
👋Sir, very good diagnostic,blessings
Well done
Nice Work as usual! Wow, after 2 fuel pumps and same issue, ??? But 5, Oy Vey.. And they probably tossed out 4 good pumps..
