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.
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.
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.
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.
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.
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.
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. !
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.
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'.
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 🥰
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!
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
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.
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.
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.
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 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!
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.
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)
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!!
@@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.
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

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!
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!
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 😂
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.👍
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.
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.
great logic, but as soon as I see anything that did not come with the vehicle like push starts exc. I get real nervous to pop the hood. Good story complaint was crank no start ok check fuel pressure, spark and visual inspection, truck had 2 car battery's one was tethered in with AMP wire, inline fuse insert wirers everywhere, and the kicker no fuel pressure cause somebody in the family removed the fuel pump. What they did with said fuel pump remains a mystery till this day. I just had to reevaluate why I do mobile mechanic work afterwards. Great job and have a Blessed day
DUDE,,, WHO ARE THESE LEWIS TOWN MECHANICS WHO ARE WORKING ON THIS CAR. A TWENTY-YEAR-OLD CAR THEY STRUGGLE WITH. WELL, IT LOOKS LIKE YOU'VE TAKEN OVER KEITH'S STATEN ISLAND RUN SHOULD BE SOME REALLY INTERESTING CASE STUDIES. HOPE THEY DON'T HAVE YOU STRUGGLING THE WHY THEY HAVE COREY BEING PUSHED AROUND OUT THERE THANKS FOR THE VIDEO !!!
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!!
Amazing...All that was needed to truely diagnose this was the fuel pressure gauge...but instead people just start throwing parts at it. If only all of them were so simple.
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! 👍
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.
I know it's not the problem on your truck but i had one of our 2001 S-10's with the 4.3 that had similar symtoms. It would start with the booster hooked up. It ended up being a broke brush spring in the fuel pump motor! Those distributors would wear out the distributor housings frequently. Good job!!
I am a proud owner of a 2000 GMC Sonoma. 17 years and it's never left me setting somewhere. Once in college I had to ask a stranger to crank it while I beat on the gas tank. P.s. these are super sensitive to aftermarket distributors. AC delco only.
Especially the cap and rotor, which technically is part of the distributor but even aftermarket cap and rotor will cause all kinds of problems. I did a tune up on my 97 s10 4.3 engine, I thought I did good with the top of the zone had to offer, it wouldn't start when it rained or was damp outside, loss of power especially on the highway, so I went to advance auto and got their top of the line cap and rotor, the same result, I started thinking it was the injectors but without a scan tool I was just guessing. My truck became unusable, I did some digging on the ole interweb and found a thread on a gm site where a guy described everything I was experiencing and the fix, a Delco cap and rotor, I thought that it couldn't be that simple but I had nothing to lose. Advance happened to carry Delco too at the time and it was cheaper than even eBay, I picked them up installed them, that was maybe seven years ago and I haven't had a problem since
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
You know you're in trouble when you see multiple things bypassed by buttons screwed to the dash. Knew a mechanic once that replaced his ignition switch with a series of toggle switches on the dash and a push button. You had to know what position to put each switch in to get it to start. :)
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!
WTF...all these push buttons, OMG good thing we have the Ivan on the job to sort out this cluster....! Wow twisted fuel hose never saw that on before, good diag!
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!!
That is what I was thinking too. I have two 98 Chevrolet trucks that has the cam offset readings, though one is a 5.7L and the other a 7.4L but they still have the same specs.
Junkyard parts can work but they also can sit for years before being re-used and you know the saying " If you don't use it, you lose it ". Many things can go bad when sitting untouched for a period of time. When using a parts cannon, new or original only.
awesome. everytime I deal with fuel pressure it gets an amp test/ rpm diagnosis. find the amount of reoccurring commutators in milliseconds then multiply by 60,000 and that's the rpm. check brushes and rpm for restrictions or in tank hose leaks ect...
Yea those old GM CSFI systems won't start or run on anything less than 55 psi, I got burned by that before thinking fuel pressure was good when in fact it was too low.
These trucks were also known for bad grounds to the fuel pumps. It would cause the wiring to melt at the pump. Its why so may aftermarket pumps came with different connectors you had to splice in place of the factory connection. I actually had to make a new ground to the chassis at the pump to get a ground. Also the fuel pressure regulator is inside the intake and if it leaks it will flood it. BTW, The pressure should build instantly.
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?
I know Im late but the timing offset can be off when someone does a intake manifold gasket reseal. Most of the time the timing is on the outer phase of the cycle and to much for the PCM to correct. If the paint mark is still there and is aligned and still out its a good possibility someone got the dis a tooth off. Wow they had a lot of Parts Canons lol.
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.

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.
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'.
Another outstanding video. Love that you'll verbally explain the thought process and escalate the procedure as necessary.
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 🥰

But then Ivan found a kink in the fuel line right after the filter. There was that AH HA moment. lol. Nice work Ivan!
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!
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
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 😅😅😅

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! 😂😆
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! 👍
Basics first, nothing like old school technique with visual inspection,boy you travel all over, good job
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.
The car doctor won again man myfriend you are dam good buddy godbless and stay safe
"No one cares..."
One of my favorite quotes when reading pids.
You are the best. I would not have imagine you couldn’t get an idle with a little low pressure
WOW! Real diagnosis, Rare
I know it's not the problem on your truck but i had one of our 2001 S-10's with the 4.3 that had similar symtoms. It would start with the booster hooked up. It ended up being a broke brush spring in the fuel pump motor! Those distributors would wear out the distributor housings frequently. Good job!!
Nice work!
Fuel regulator?
With the prices of used cars today, I hope the owners gave you a little bonus, especially being a mobile mechanic in cold weather.
I am a proud owner of a 2000 GMC Sonoma. 17 years and it's never left me setting somewhere. Once in college I had to ask a stranger to crank it while I beat on the gas tank.
P.s. these are super sensitive to aftermarket distributors. AC delco only.
Especially the cap and rotor, which technically is part of the distributor but even aftermarket cap and rotor will cause all kinds of problems. I did a tune up on my 97 s10 4.3 engine, I thought I did good with the top of the zone had to offer, it wouldn't start when it rained or was damp outside, loss of power especially on the highway, so I went to advance auto and got their top of the line cap and rotor, the same result, I started thinking it was the injectors but without a scan tool I was just guessing. My truck became unusable, I did some digging on the ole interweb and found a thread on a gm site where a guy described everything I was experiencing and the fix, a Delco cap and rotor, I thought that it couldn't be that simple but I had nothing to lose. Advance happened to carry Delco too at the time and it was cheaper than even eBay, I picked them up installed them, that was maybe seven years ago and I haven't had a problem since
@@Peter-pv8xx it took me years to figure it out. I had the exact problem. High humidity, intermittent horrible misfire and zero engine codes.
Congratulations! I have never guessed correctly. I was thinking about low voltage at the fuel pump.
That was a great diagnosis video.
When you finally got it running right you should have said “Whoa - Chevy thunder!”
Not surprising to see something twisted up like that from an Auto Wrecker!!! Good job catching that!!
All the best from Canada
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
You know you're in trouble when you see multiple things bypassed by buttons screwed to the dash. Knew a mechanic once that replaced his ignition switch with a series of toggle switches on the dash and a push button. You had to know what position to put each switch in to get it to start. :)
Doubles as a security system
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!
WTF...all these push buttons, OMG good thing we have the Ivan on the job to sort out this cluster....! Wow twisted fuel hose never saw that on before, good diag!
Great troubleshooting skillz 👍👍💗
Ivan you are the man once again!!!!!
Honestly, this are goooood diagnostic.
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!!
U can adjust the distributor just have to grind the hold down. It is supposed to be + or - 2 degree
That is what I was thinking too. I have two 98 Chevrolet trucks that has the cam offset readings, though one is a 5.7L and the other a 7.4L but they still have the same specs.
That was a very cool find, kinked fuel line. Thanks Ivan!
Awesome Job and Troubleshooting.
Junkyard parts can work but they also can sit for years before being re-used and you know the saying " If you don't use it, you lose it ". Many things can go bad when sitting untouched for a period of time. When using a parts cannon, new or original only.
Great Job as usual!
Great job sir, the definition of insanity is trying the same thing over and over again expecting different results!
You are the Man !!! Love your work.
awesome. everytime I deal with fuel pressure it gets an amp test/ rpm diagnosis. find the amount of reoccurring commutators in milliseconds then multiply by 60,000 and that's the rpm. check brushes and rpm for restrictions or in tank hose leaks ect...
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.
Yea those old GM CSFI systems won't start or run on anything less than 55 psi, I got burned by that before thinking fuel pressure was good when in fact it was too low.
Nice diag my friend. We think alike. I went right to fuel delivery about the same time you did.
These trucks were also known for bad grounds to the fuel pumps. It would cause the wiring to melt at the pump. Its why so may aftermarket pumps came with different connectors you had to splice in place of the factory connection. I actually had to make a new ground to the chassis at the pump to get a ground. Also the fuel pressure regulator is inside the intake and if it leaks it will flood it. BTW,
The pressure should build instantly.
Nice diag! Sometimes it's as easy as a twisted fuel line.
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?
Nice, Ivan. Another no parts required.
Not very usual problem , great diag 👍🏻
Great diagnosis Ivan!
I know Im late but the timing offset can be off when someone does a intake manifold gasket reseal. Most of the time the timing is on the outer phase of the cycle and to much for the PCM to correct. If the paint mark is still there and is aligned and still out its a good possibility someone got the dis a tooth off.
Wow they had a lot of Parts Canons lol.
Q: "hey what parts did you try changing?" A: """all of them""" 🤣🤣🤣
