That bashing on the tank trick has gotten me out of the weeds before when I had a fuel pump on its last legs. Driving around with the rear seat removed bashing the crap out of it with a hammer at the stop lights as it stalled constantly under no throttle on the way to the mechanic, good times!
Your damn way to find out if it's a fuel pump and filter, is if one is to think, 'because of a precise time of failure, and when it runs 'intermittently', sometimes great, up until anti drug law protesters or Green Party protesters, organized crime syndicate and or NRA, KKK, BLM protesters find out what your doing', 'Using alien government satellites these people of the Roots Of All Evil are gonna shut down this high payed for car, in the most inconvenient times'; one would know it's a fuel pump or fuel filter. This attitude, way of thinking, overwhelmingly, is obviously tormenting the users, when a filter takes out a fuel pump, a bad fuel pump. That's for sure. Perhaps in the nearby future demented alien governments will zap your cars, but one will know the difference. That enemy will destroy the cars for everyone. Except in the case of Dr. Bloomberg and them unwanted evil people who like to hurt us on a personal side. Then everybody's gosh darn Gone In Sixty Seconds. Except for if one has a 😮🎉early model Mercedes Benz. 🦜🦚Steal one of those. 🌵🌵🌵
Hi Matt, I have the exact same problem with my Alfa Romeo 156 2.0 Twin Spark. Does not start, the fuel pump makes a noise but not the usual I used to hear. Your video just reminded me of what's going on with my car. No fuel coming in, just a tiny bit of fuel, not your usual spray. Man, you ROCK!!!!! Your channel should be renamed the REAL MECHANIC.
That's cool that you're respectful to your neighbors, and don't make a lot of unnecessary loud noise at night. I try to teach the same thought process to some of the younger kids I work with. How it's not fair to work past 10 p.m. when you have other people that live close by.
Very comprehensive troubleshooting. Details diagnostics. Real interesting. Anybody that can't appreciate this type of troubleshooting can learn alot from this video. It's also great for sifting out bad connections the major culprit in a lot of this.
I'm glad your channel popped up on my feed. I'm also a limited do it yourselfer, recieving constant criticism from others to just "take it to the mechanic". With limited funds and 4 cars constantly breaking down, I'm forced to become the "designated mechanic". I have a new diy fire under my ass, thanks to your vids!
This is a great video. The little quirks that had to be dealt with like proper ground meant everything. These are the buggaboos that dog an amateur like me. That was as impressive when you you pulled out the power probe. GREAT STUFF!
Thanks for putting driveway diagnostics videos up. It seems that with your video the only way crooked mechanics can rip people off is by NOT telling the customer whats really wrong with their car.
Way to go Michelle I as well have learned so much from these videos and I have been working on engines for over 50 years but these newer vehicles are proving a tough challenge even for seasoned mechanics
New subscriber here , as a DIY maintaining 3 cars in the family I thought my next move was to buy a scanner , which one I do not know, great to see a simple test light and a your FASTTEC method will take care of so many problems , learning so much , thanks for sharing !
Thank you very much for this great idea. I’m a single mother and five months pregnant and I don’t have a whole lot of money coming in but I do have a test late. Since the car won’t start I can’t drive to Harbor Freight to buy a multimeter and couldn’t afford the $150 deposit to borrow a fuel pressure checker set up from O’Reillys therefore I thought I was out of luck lol. This message just saved me a lot of stress and extra time and money.
5:30 Would have immediately removed the air intake, sprayed either some starting fluid or brake parts cleaner (carb cleaner? Either one I suppose, heard BPC is more atomized, evaporates quicker, not sure if that is true or true every time but this sticks in memory,) really good amount like spray for 5 seconds, see if it runs off of that. This of course will tell you if there is spark etc, if going int he direction of fuel. This is my first comment perhaps ever but, Mr. Schrodinger, I really like your channel and I presently have a Corolla in the garage I am letting a lot of MMO (Marvel Mystery Oil) soak on the pistons for a very long time, for no reason really. Compression numbers when warm (I know, I know, but. Still) were 188-188-192-190. Car runs mint. Love your channel and I look forward to interacting more.. you have a channel for we intelligent folks. I knew a parts changer once and it just didn't work out.. Had to tell her, "I'm done."
I knew it. My car had a po340 code and before I even replace any sensors, when I try to start it it sounded just like this. There was an actual time when it started but then shut up. So I just did what the code said and replaced the sensor and the wiring and still no start. I kept saying that Obd 2 scan tool is wrong about the P0340 being a camshaft position sensor. Because this video confirms that my fuel pump went out I don't even have to do a diagnostics check cuz I already know. Your video helped me out.
Nice work with the test light! If you have not already and your vehicle is more than 10 years old, upgrade your AAA card for the free 100 mile tow. Diagnostics are great but you still need to get a broken down vehicle to a repair shop/mechanic.
Yeah I always do my best to try to save the customer any fees with towing etc but at the time there was no way I was getting under the vehicle in my suit lol. Towing was only option!
I thought about carrying tools. Realized that I cannot carry all the possible repair parts too. So, unless it is a battery jump start or changing a flat tire the vehicle is getting towed. The AAA upgrade to the Plus Membership for about $88 annually with the 100 mile tow will save your clients $$$. I believe you have to be a standard AAA member for 90 days first to qualify. The road side visit was good moral support though.
I’ve watched it seems 100s of vids but you brother far exceed them all. You know your stuff. Soooo thankful I ran across you. Had to sub just no way around it.👍👍👍
I've had some people that argued with me over fuel pumps. They said if you hear it running, then it's good. You just proved my point even more. Mine went out on my F150 as well as a 4runner. Both would prime, but both were weak. Replaced and both run great. The fuel pressure on both vehicles were just below what is recommended. Still, those asshats continued to argue over it lol.
Oh man dude- I have what- 4 videos showing clearly that a running pump did not meet fuel pressure specs?? WHoever you are arguing with needs a serious throat punch!!! There is no argument- a running pump does not mean it isn't the problem! Throat punch them for me too!!!!
Hey there! I think you are great teck, It's really nice to know that you have a channel. I've seen a few of your videos and have learned a few tricks and I want top say thank you for your knowledge. I have become a subscriber.
Hahaha you noticed!!! Indeed that is exactly what I did at the field call too. In fact the owner thought it was a special tool just for that purpose hahaha.
You do good methodical. work. I wish I was your neighbor. Now I have a crank no start with my 2002 5.4L F-150. lol FP is around 35psi. It will occasionally fire up if I apply slight amount of throttle before turning the key. Once it starts, it runs fine.
@@SchrodingersBox Will do. How does applying 1/8-1/4 throttle, before turning the ignition, affect starting in a EFI vehicle other than letting in a little more air flow? It certainly does help, although not every time, start my truck.
There are several reasons for that including the possibility it’s not a lean condition problem- maybe the throttle body is dirty so the IAC is not allowing enough air when starting. But for a lean condition it might be the slight throttle application induces a higher injector pulsewidth to allow more fuel at startup but without throttle being open too much to still lean it out.
LOL. Oreillys dropped by and gave us all one of those head lights the other day. We had good luck with them....well, I saw everyone using them for a while, I mostly use a magnetic light, but I'm happy it's in my tool box.
I have a 96 blazer 4.3 bought with motor out being rebuilt. Finally got all together ,fluids in ( break in oil of course). Put a battery in and nothing. No spark at the battery, no lights no nothing. Ground? Still checking. Love your videos
Nice support for OZ. That was classic. I truly enjoy your methodical approach to diagnoses/diagnosis? Anyway, great video and a good reminder to always check your test equipment. Thanks for the lesson.
The saddest part about the automotive industry is that they are not making it easy to figure out why a vehicle isn’t starting. There has to be better code development for quicker diagnoses.
@Hagbard Celine well you have to, an old person with a pen and pad cant interact efficiently with a software based platform. A scribe of the 14th century wont comprehend a word processor system. You have to transfer skillset across platforms by being versatile with concepts/ principles so one can achieve desired affect. The homie's channel here is evident to what I mean.
Wish you lived in my area I would definitely pay u to fix my 2002 Tahoe... I installed a New fuel pump a new fuel filter all new fuses and relays. But. no fuel pressure no prime... only cranks.... Been sitting for 2 months can't seem to fix it.... got to walk to work until then... But great job love the videos.
I have this same issue with my 2002 ls 3.9l, my replacement sending pump located on the driver side is due to come in tomorrow, have already checked the fuses as well as the relay and replaced, battery is new, so next option would be the sending unit as I was told the passenger side unit has already been replaced, and these pumps are rated for 10yrs/150k, good looking out on the diagnosis and being sure of the issue, hopefully this will stop me from spending money on unnecessary repairs.
Cannot believe 8 dislikes already! Very quick diagnosis and using only a cheap test light, what is not to like? Looking forward to seeing you on your new website in a few months time Matt.
your’re right. that way I could call and cover towing for all the ricers when I blow their doors off. Plus their cars will actually go faster after making use of their tow hooks for once.
Well I would be all for that but you still have a 4 hour ride east from from Pitt but you are always welcome and I have about 4 vehicles with codes that we can look at so no shortage there. So anytime my friend!
I saw an episode where he noticed a 12 hp Kohler engine smoking and running like the choke was half-way on, MacGyver pipes up "Hey, looks like you've got a busted piston there!" Pulls the engine apart to reveal a broken-in-half connecting rod, then uses some coins (usually made of Nickel, a different metal) held in the alligator clamp of some jumper-cables to arc-weld the aluminum halves of the connecting rod together. I was disgusted, it isn't a compliment to refer to any mechanic as "MacGuyver"
Love the T-shirt! You never know about a pump (unless you have X-ray vision). I had a plastic baffle come loose inside a metal tank on a K5 Blazer 30 years ago and twisted the sending unit and took out a pump. Just part of the sh#t you see in this business...
Thank you for the diagnosis with just a test light because I don't have diagnostic tools other than a voltmeter & test light. Changed out the fuel pump but have an intermittent crank no start. Check engine light doesn't light up with key in On Position. No blown fuses. Not clear how you are jumping the relays. Will watch again
Having an issue with no crank, no start. The lights are nice and bright and all accessories work. Then after a couple of tries cranking it starts like normal, runs and sounds normal. The battery was replaced, went to Autozone and they tested bay, starter and alternator they came back good. The car did code with a p1399 misfire. I was wondering if the starter relay, cylinder or spark plugs, fuel pump or ignition switch, to start diagnose. The oil is maintained. I did find that I needed a cylinder coil due to rough idling about a year ago. This was an Acura TL 2001. Your insight much appreciated!
Hey Matt so good to hear and see you again. Hoping all has been good with your work and family life. Do keep all posted of any upcoming paid website. I admit I bailed on you shortly after you started your new job title. I thought you’d not have a lot of time open. However please forgive my doing so.
A definitive diagnosis. Maybe it's just me, but I probably would have given it a shot of starting fluid to get to run for a few second, just to make sure there wasn't any other problems. The fact that it was trying to start with a little pressure probably means it was okay. However, there have been a few occasions when I find something wrong, tell the customer a price, fix it, and I discover it an additional issue.
Nice job, I have a 460 --- Will F P R keep an engine from starting --Just bought this rig RV - It was running but not great and revving it up and it would back fire. ---- Drove it a few miles, couldn't make the hill! Backed it down the hill. Then after shutting it off, I have only been able to start it one time! For a minute or so! Now I can't get it to start! ---- put in new plugs,, wires, Throttle Position Sensor. Rotating the timing! Puzeled !!!! I do Disaster Relief, but not going anywhere until I am up and running! Also switched the relays, and did a fuel pressure test - 45 - took a minute and a half to drain off to 35 , figure that was the hook up. Requires at least 35 and top out at 45 PSI Checked the line, took the line apart after the fuel filter! Thanks, Any Ideas!Thanks, Rick
Unlikely. I would start with basic diagnostics data you used for the TPS- why was that changed? What data indicated it was bad? That would be a major, major clue! ALso why change the plugs and wires- what was the spark problem you identified- was it failing to give spark at all cylinders only under load? Need better explanation of your data before I can help.
So methodical. I genuinely can't believe that even 5% of professional auto technicians have this guy's diagnostic skills. They don't teach that level of science at tech school.
Great video! I'm trying to diagnose my 4.3 GMC Sonoma and I've had similar issues. We thought it was the fuel pump at first because I couldn't hear it when I turned the key, but after looking it turned out the coil wasn't getting a spark. Traced it to the fuse box and the ECM fuse was melted! We could barely get it out. After replacing the fuse the fuel pump engaged and I can start my truck and drive it but after a while the fuse will blow again. I've got no idea what's going on or even where to go from here.
In other words the material is way over your head. I always seem to get comments like that from simpletons who don’t understand basic electrical. Why don’t you tell us your method of how you would do this. Or like all the other basic bitches are you found to remain silent because you can’t even plug in a toaster much less diagnose this better than me?
incorrect again. It’s the RIGHT way or no way. It just happens to be aligned with my way which is point of this channel- to show the right way to diagnose. show where i am wrong if you disagree otherwise quit babbling like a fool. all you have to do is show where i am wrong.
The fuel pump made no sound and the starting was no different than any other no fuel or no spark condition. There is no possible to way to tell it is a bad fuel pump from the starting sound.
The way it cranked. Not trying to annoy you sir, but yes..when it cranks and doesnt start like that, it's almost always the fuel pump. My father was a grade A mechanic, im almost as good as he was. And I now that sound. I'm just saying within 5 seconds of you starting it, I new it was the fuel pump. Still an interesting video and diagnosis.
You moronic fool- the Blah Blah IS the repair help. I always get comments like this from basic bitches who just turn wrenches but have no idea how to do diagnostics. Look at the comments from intellectual people, now look at yours. Feel stupid?
@@SchrodingersBox Does talking down to people make you a better person? Anyone who questions or disagrees is immediately cursed and accused of being a moron or other names I won't repeat. Why the attitude?
@@SchrodingersBox do you happen to know what the fuel pressure is supposed to be for a 2002 Chevy Trailblazer?? I can't find any specs online..? I think my fuel pump has become to weak to keep enough pressure( crank no-start) the pressure is reading 43... ? TIA
OMG sorry to hear that. It must suck that you are so stupid, because you can clearly see the test light EVERY TIME in this entire video!!! EVERY TIME! Show me ONE TIME you cannot see the testlight. Otherwise you just look stupid. Show ONE TIME!! Basic bitches... SMH. You should just stick to changing oil, pal!
@@SchrodingersBox if you know everything that he is saying then why the fuck are you wasting your time watching the video? That is retarded. EVERY TIME! People who don't know and want to learn more are so fucking stupid right!?
@@SchrodingersBox He did not say that he couldn't see the light. He could not see what you were doing to affect the light. Lighten up! No need to be abusive!
Paul you incompetent moron. THINK. The video explains exactly what the test light is doing and why i make the interpretation. It’s clear you don’t understand what a test light is.
@@SchrodingersBox What's clear is that you don't read what people say with understanding. I said nothing about MY understanding of the purpose and function of the test light. I was restating the viewer's concerns. He was just talking about NOT SEEING what you were doing to turn the light on or off, not your interpretation. Calling me insulting names just verifies your need for psychological inrervention!
Indeed it is!! I can see where they'd get pissed with the air tools, tow trucks, and absolute jankity cars always outside my house in a nice neighborhood but they are very supportive especially when they know most of it is for charity!
You should change to my theory of idiots thinking they understand business models when they actually have no clue. Chris Fix is a completely different target demographic than what I pursue. You won't find him doing near the diagnostic level I do here. That should be blatantly obvious even to a complete idiot, but like I said, my theory is accurate. Besides- my paid channel alone earns more income than Chris makes with his free channel. And you think his business model is better ROtfLMAO!!! Please- you not only substantiated my theory, you proved it conclusively. The only incompetent businessman seems to be you my friend.
I just want to say this not to be mean just to be a friend I think your channel is great I think you are very brilliant you just need to take criticism a little bit better I mean it's that guy's opinion even though he's wrong that's his opinion you shouldn't get so worked up about it to make a comment just let it go be above it like you are
...100% scientifically conclusive hahaha! I’m sorry, but I came across this channel while doing some fuel system research, and I have to to agree that there was WAY too much “side chatter”. by the end of the video I had forgotten what he was trying to demonstrate. However, it’s clear that he’s on a much higher level of intelligence than the “average folk”, which is why he’s “quirkier”. I absolutely got nothing educational out of this video, but the comments were priceless... and how many people just like us sat and watched the entire video...some of which have even posted comments(good bad indifferent)? He’s clearly doing something right whether it’s intentional or not! Lol. @schrodingers box- I would suggest “dumbing it down” for those of us who aren’t mechanical geniuses, and try to just focus on the “1-2-3’s”. Short, simple and easy to follow.
As techs’ we get good at the no-start diagnosis and 99% of the time it’s real quick like this. Then you get those buggers that you take need two whole days and a lab scope and a couple after hours beers to get it figured out.
20 psi is the low end of pressure that the injectors would get a decent spray pattern. I'd hook up a pressurized can of carb cleaner to the schraeder to test.
It's perfectly understandable that the guy didn't want to unload the car in the driveway because there's a liability issue, especially one that has a good incline.
Yes Zib is right- it's a liability thing. I usually use the same driver and he really hooks me up (no pun intended lol). I have a severe incline on my driveway and yet still the guy lines up even SUV's to just roll right off the ramp into the bay without hitting my garage door or scraping my concrete. He's amazing. But whenever customers choose their own driver much more often than not they drop it in the street, and this guy in the video even spent 2 minutes taking pictures all over the car to boot!!
Give specific examples. It is quite obvious otherwise to hundreds of thousanmds of people that you just don't understand what is happening here- it's simply too far over your simpleton head.
That bashing on the tank trick has gotten me out of the weeds before when I had a fuel pump on its last legs. Driving around with the rear seat removed bashing the crap out of it with a hammer at the stop lights as it stalled constantly under no throttle on the way to the mechanic, good times!
I learn more here than in the 5 year working as a technician. We need more real teachers like you.
I agree Marcus. Retired mechanic and college shop teacher hear, but you can never stop learning. He makes great video's

Your damn way to find out if it's a fuel pump and filter, is if one is to think, 'because of a precise time of failure, and when it runs 'intermittently', sometimes great, up until anti drug law protesters or Green Party protesters, organized crime syndicate and or NRA, KKK, BLM protesters find out what your doing', 'Using alien government satellites these people of the Roots Of All Evil are gonna shut down this high payed for car, in the most inconvenient times'; one would know it's a fuel pump or fuel filter.

PowerProbe and Test light have their uses indeed! Nice troubleshooting with those tools.
Actually could have done the definitive diagnosis entirely with a power probe only if you think about it, but not with a test light only.
All with a test light ,even pushing the Schrader valve 💪

what does a constipated Schrodinger mechanic deal with stuck poop? Works it out with a test light

Merry Christmas Matt for you and your family i hope you have a great Christmas.
You do good methodical. work. I wish I was your neighbor. Now I have a crank no start with my 2002 5.4L F-150. lol
FP is around 35psi. It will occasionally fire up if I apply slight amount of throttle before turning the key. Once it starts, it runs fine.
I would do a fuel trim analysis when engine is running to check for lean condition especially under load. if so, address fuel pressure.

But for a lean condition it might be the slight throttle application induces a higher injector pulsewidth to allow more fuel at startup but without throttle being open too much to still lean it out.
Thanks for a video using tools anyone can afford!
LOL. Oreillys dropped by and gave us all one of those head lights the other day. We had good luck with them....well, I saw everyone using them for a while, I mostly use a magnetic light, but I'm happy it's in my tool box.
Schrodingers fuel pump. Both dead and alive until observed. 🤔
Good diagnosis. Nothing beats the test light. It's always my go to diagnostic tool.
nothing beats a test light until the hard to find bulb burns out
Very good demonstration my friend thank you very much for your very valuable time like always excellent teachings
You are very welcome
Thank you Matt. Merry Christmas to you and your family.
I have a 96 blazer 4.3 bought with motor out being rebuilt. Finally got all together ,fluids in ( break in oil of course). Put a battery in and nothing. No spark at the battery, no lights no nothing. Ground? Still checking. Love your videos
What data do you have? Whats your voltage on the ground for the ignition showing?
Nice support for OZ. That was classic. I truly enjoy your methodical approach to diagnoses/diagnosis? Anyway, great video and a good reminder to always check your test equipment. Thanks for the lesson.
"Your basic bitches are gonna say, check the fuses." Ah that had me rolling. 😂
The saddest part about the automotive industry is that they are not making it easy to figure out why a vehicle isn’t starting. There has to be better code development for quicker diagnoses.
@Hagbard Celine well you have to, an old person with a pen and pad cant interact efficiently with a software based platform.
A scribe of the 14th century wont comprehend a word processor system. You have to transfer skillset across platforms by being versatile with concepts/ principles so one can achieve desired affect. The homie's channel here is evident to what I mean.
sad? they dont want you to fix it. They want you to take it in and spend, spend, spend..
I'm😂
@@tedporciuncula3385😂definitely right
They do that so you either take to dealer to get fixed or mechanic
Wish you lived in my area I would definitely pay u to fix my 2002 Tahoe... I installed a New fuel pump a new fuel filter all new fuses and relays. But. no fuel pressure no prime... only cranks.... Been sitting for 2 months can't seem to fix it.... got to walk to work until then... But great job love the videos.
Cam position sensor gone bad
Maybe he makes house calls lol
or perhaps we can clone Eric
I’m very happy to follow you Matt, such a great teacher. Actually...the best teacher of all time, buddy!
Thanks my friend.
Love the new "Load Probe!" and all of $3 ... thanks for the video,Best regards
Matt use the ground lead on you powerprobe as the ground for your test light
Ha should have thought of that lol!!
I have this same issue with my 2002 ls 3.9l, my replacement sending pump located on the driver side is due to come in tomorrow, have already checked the fuses as well as the relay and replaced, battery is new, so next option would be the sending unit as I was told the passenger side unit has already been replaced, and these pumps are rated for 10yrs/150k, good looking out on the diagnosis and being sure of the issue, hopefully this will stop me from spending money on unnecessary repairs.
Cannot believe 8 dislikes already! Very quick diagnosis and using only a cheap test light, what is not to like? Looking forward to seeing you on your new website in a few months time Matt.
it’s because basic bitches don’t understand what i am doing lol.
And yet here you are David- watching all of my videos lol.
@@SchrodingersBox again, without the basic bitches you have no fucking market...duhhhh. Exact reason people fucking HATE snake mechanics

What's up Eric! Us Trans Am guys love our Trans Ams!!
Very good job you doing very good job
Nice video 👌👌👌👌
Very good teaching 👌 👌👌
you are just like McGyver! you will soon be able to diagnose with a pen knife and a match stick! Man I would love a shameless plug! great video Matt!
Better yet how about i come to Pitt and we diagnose that car with the poor performance that probably has a rats nest growing in it by now.
Well I would be all for that but you still have a 4 hour ride east from from Pitt but you are always welcome and I have about 4 vehicles with codes that we can look at so no shortage there. So anytime my friend!
We'll talk....
Sounds like future videos! :)
I saw an episode where he noticed a 12 hp Kohler engine smoking and running like the choke was half-way on, MacGyver pipes up "Hey, looks like you've got a busted piston there!" Pulls the engine apart to reveal a broken-in-half connecting rod, then uses some coins (usually made of Nickel, a different metal) held in the alligator clamp of some jumper-cables to arc-weld the aluminum halves of the connecting rod together. I was disgusted, it isn't a compliment to refer to any mechanic as "MacGuyver"
you are awesome .. i really enjoy your videos

I think he was a Siamese cat in a past life . MEOW !
Nice quick logical diagnosis Matt!
They aren't always quick but they are always logical lol. In this case it happened to be both!

Thank you, awesome video.
Sometimes you can take a rubber mallet and bang on your tank and sometimes that fuel pump to start working sometimes
Love the T-shirt!
You never know about a pump (unless you have X-ray vision). I had a plastic baffle come loose inside a metal tank on a K5 Blazer 30 years ago and twisted the sending unit and took out a pump. Just part of the sh#t you see in this business...
What is that term Eric O uses for Chevy? Sh***y? Know I know why
Thank you for the diagnosis with just a test light because I don't have diagnostic tools other than a voltmeter & test light. Changed out the fuel pump but have an intermittent crank no start. Check engine light doesn't light up with key in On Position. No blown fuses. Not clear how you are jumping the relays. Will watch again
What was your data the fuel pump was bad based on the testlight results? I would start there for sure. Also what was your voltage drop reading?
Did you pull the paper clip out of the control side on relay before you sent 12 volts with the power probe?
No- because the circuit was open anyway since the pump was unplugged.
Having an issue with no crank, no start. The lights are nice and bright and all accessories work. Then after a couple of tries cranking it starts like normal, runs and sounds normal. The battery was replaced, went to Autozone and they tested bay, starter and alternator they came back good. The car did code with a p1399 misfire. I was wondering if the starter relay, cylinder or spark plugs, fuel pump or ignition switch, to start diagnose. The oil is maintained. I did find that I needed a cylinder coil due to rough idling about a year ago. This was an Acura TL 2001. Your insight much appreciated!
what data do you have?
Matt, I experienced a frisson of excitment as the message alerting me to a new video came through.
And you’re even first commentor lol!
Hey Matt so good to hear and see you again. Hoping all has been good with your work and family life. Do keep all posted of any upcoming paid website. I admit I bailed on you shortly after you started your new job title. I thought you’d not have a lot of time open. However please forgive my doing so.
A definitive diagnosis. Maybe it's just me, but I probably would have given it a shot of starting fluid to get to run for a few second, just to make sure there wasn't any other problems. The fact that it was trying to start with a little pressure probably means it was okay. However, there have been a few occasions when I find something wrong, tell the customer a price, fix it, and I discover it an additional issue.
Yes at the time i was with customer wanted to do that but there was none around. I could have done it in the garage i suppose.
I too give it a shot of starter fluid. Good way to verify it's only a fuel delivery concern. Great video.

Nice job, I have a 460 --- Will F P R keep an engine from starting --Just bought this rig RV - It was running but not great and revving it up and it would back fire. ---- Drove it a few miles, couldn't make the hill! Backed it down the hill. Then after shutting it off, I have only been able to start it one time! For a minute or so! Now I can't get it to start! ---- put in new plugs,, wires, Throttle Position Sensor. Rotating the timing! Puzeled !!!! I do Disaster Relief, but not going anywhere until I am up and running! Also switched the relays, and did a fuel pressure test - 45 - took a minute and a half to drain off to 35 , figure that was the hook up. Requires at least 35 and top out at 45 PSI Checked the line, took the line apart after the fuel filter! Thanks, Any Ideas!Thanks, Rick
Unlikely. I would start with basic diagnostics data you used for the TPS- why was that changed? What data indicated it was bad? That would be a major, major clue!
ALso why change the plugs and wires- what was the spark problem you identified- was it failing to give spark at all cylinders only under load?
Need better explanation of your data before I can help.
So methodical. I genuinely can't believe that even 5% of professional auto technicians have this guy's diagnostic skills. They don't teach that level of science at tech school.
Thanks for the heart, Matt. I'm still searching for that email address.
erwinschrodingersbox@gmail.com
@@SchrodingersBox Thanks a lot, Matt.
Great video! I'm trying to diagnose my 4.3 GMC Sonoma and I've had similar issues. We thought it was the fuel pump at first because I couldn't hear it when I turned the key, but after looking it turned out the coil wasn't getting a spark. Traced it to the fuse box and the ECM fuse was melted! We could barely get it out. After replacing the fuse the fuel pump engaged and I can start my truck and drive it but after a while the fuse will blow again. I've got no idea what's going on or even where to go from here.
What amperage is the pump drawing? You need to start there for sure.
Lol love the integrity
I love this channel massive mechanic swag hats off to u sir...
Weird science guy, to much talking and no room for a period. Run-on conversation...just annoying
In other words the material is way over your head. I always seem to get comments like that from simpletons who don’t understand basic electrical. Why don’t you tell us your method of how you would do this. Or like all the other basic bitches are you found to remain silent because you can’t even plug in a toaster much less diagnose this better than me?
@@SchrodingersBox Boy, you are really full of yourself!
hardly. Just standing up for the correct perspective and it appears neither of you have it.
@@SchrodingersBox yeah, it's your way or no way!
incorrect again. It’s the RIGHT way or no way. It just happens to be aligned with my way which is point of this channel- to show the right way to diagnose. show where i am wrong if you disagree otherwise quit babbling like a fool. all you have to do is show where i am wrong.
You sure have awesome neighbors!
Yes I do!
11:43 One Handed Quick Disconnect Sleight Of Hand... #MagicianTechnician
Nice video and diagnosing, but I knew it was the fuel pump as soon as you started it. The sound it always makes.
The fuel pump made no sound and the starting was no different than any other no fuel or no spark condition. There is no possible to way to tell it is a bad fuel pump from the starting sound.
The way it cranked. Not trying to annoy you sir, but yes..when it cranks and doesnt start like that, it's almost always the fuel pump. My father was a grade A mechanic, im almost as good as he was. And I now that sound. I'm just saying within 5 seconds of you starting it, I new it was the fuel pump. Still an interesting video and diagnosis.
My goodness when does the repair help start,,,,,.,bleh bleh bleh
You moronic fool- the Blah Blah IS the repair help. I always get comments like this from basic bitches who just turn wrenches but have no idea how to do diagnostics.
Look at the comments from intellectual people, now look at yours. Feel stupid?
hahahaha damn arm chair mechanics
Have same car same problem helped me!🤔😎
@@SchrodingersBox Does talking down to people make you a better person? Anyone who questions or disagrees is immediately cursed and accused of being a moron or other names I won't repeat. Why the attitude?
@@SchrodingersBox do you happen to know what the fuel pressure is supposed to be for a 2002 Chevy Trailblazer?? I can't find any specs online..? I think my fuel pump has become to weak to keep enough pressure( crank no-start) the pressure is reading 43... ? TIA
you are a superior at diagnosis.
Thank you! Its my passion!
I CANT SEE WHAT U R DOING AND U RAMBLE ON
OMG sorry to hear that. It must suck that you are so stupid, because you can clearly see the test light EVERY TIME in this entire video!!! EVERY TIME!
Show me ONE TIME you cannot see the testlight. Otherwise you just look stupid. Show ONE TIME!!
Basic bitches... SMH. You should just stick to changing oil, pal!
@@SchrodingersBox if you know everything that he is saying then why the fuck are you wasting your time watching the video? That is retarded. EVERY TIME! People who don't know and want to learn more are so fucking stupid right!?
@@SchrodingersBox He did not say that he couldn't see the light. He could not see what you were doing to affect the light. Lighten up! No need to be abusive!
Paul you incompetent moron. THINK. The video explains exactly what the test light is doing and why i make the interpretation. It’s clear you don’t understand what a test light is.
@@SchrodingersBox What's clear is that you don't read what people say with understanding. I said nothing about MY understanding of the purpose and function of the test light. I was restating the viewer's concerns. He was just talking about NOT SEEING what you were doing to turn the light on or off, not your interpretation. Calling me insulting names just verifies your need for psychological inrervention!
I figured it out at 16:17.
Love your channel
What are Two Percenters?
2 percenters are those who are not in the 98% percent of people who woul;d have tried to fix this car by putting plugs, wires, a coil etc.....
Just above 1 percent🤣
Great to have a working relationship with neighbors.
Indeed it is!! I can see where they'd get pissed with the air tools, tow trucks, and absolute jankity cars always outside my house in a nice neighborhood but they are very supportive especially when they know most of it is for charity!
my theory of scientists being terrible businessmen seems to hold true. check out chris fix, 2.8m subs and its a free channel..
You should change to my theory of idiots thinking they understand business models when they actually have no clue. Chris Fix is a completely different target demographic than what I pursue. You won't find him doing near the diagnostic level I do here. That should be blatantly obvious even to a complete idiot, but like I said, my theory is accurate.
Besides- my paid channel alone earns more income than Chris makes with his free channel. And you think his business model is better ROtfLMAO!!! Please- you not only substantiated my theory, you proved it conclusively. The only incompetent businessman seems to be you my friend.
I just want to say this not to be mean just to be a friend I think your channel is great I think you are very brilliant you just need to take criticism a little bit better I mean it's that guy's opinion even though he's wrong that's his opinion you shouldn't get so worked up about it to make a comment just let it go be above it like you are
...100% scientifically conclusive hahaha! I’m sorry, but I came across this channel while doing some fuel system research, and I have to to agree that there was WAY too much “side chatter”. by the end of the video I had forgotten what he was trying to demonstrate. However, it’s clear that he’s on a much higher level of intelligence than the “average folk”, which is why he’s “quirkier”. I absolutely got nothing educational out of this video, but the comments were priceless... and how many people just like us sat and watched the entire video...some of which have even posted comments(good bad indifferent)? He’s clearly doing something right whether it’s intentional or not! Lol.
@schrodingers box- I would suggest “dumbing it down” for those of us who aren’t mechanical geniuses, and try to just focus on the “1-2-3’s”. Short, simple and easy to follow.
As techs’ we get good at the no-start diagnosis and 99% of the time it’s real quick like this. Then you get those buggers that you take need two whole days and a lab scope and a couple after hours beers to get it figured out.
this guy talks too much about personal stuff, people care for what they looking for not he's life or he's friends
In other words you don’t know how to use a test light. Hey don’t blame me for your incompetence.
20 psi is the low end of pressure that the injectors would get a decent spray pattern. I'd hook up a pressurized can of carb cleaner to the schraeder to test.
Policy not to unload the car in the driveway = lazy tow truck driver
It's perfectly understandable that the guy didn't want to unload the car in the driveway because there's a liability issue, especially one that has a good incline.
Yes Zib is right- it's a liability thing. I usually use the same driver and he really hooks me up (no pun intended lol). I have a severe incline on my driveway and yet still the guy lines up even SUV's to just roll right off the ramp into the bay without hitting my garage door or scraping my concrete. He's amazing. But whenever customers choose their own driver much more often than not they drop it in the street, and this guy in the video even spent 2 minutes taking pictures all over the car to boot!!
Fantastic channel, wouldnt another tip to check if the fuel pump isn't working to spray "starter fluid" into the air intake?
Yes however that checks fuel delivery- not necessarily the fuel pump.
Man you love to talk about you personal things! You should go straight to the topic.
Ummmm no... you should simply watch another channel.
Good morning thanks for sharing your experience and knowledge thanks some much
Thanks and Merry Christmas my friend !
To much unimportant info
Give specific examples. It is quite obvious otherwise to hundreds of thousanmds of people that you just don't understand what is happening here- it's simply too far over your simpleton head.
Learn to have some respect for others. Are you someone that extends a helping hand as this guy was kind enough to put out this video for people?
Thanks brother, have a great year 2024
Thank you!! So far it’s going well!
Ye have no shame, as always love your videos and knowledge
Great video as usual.
