I have a f150 and it does all the things u say if I turn the key forward and backwards it start right up I was like is the purge valve bad? But if I fill the truck up it runs fine lol any suggestions
Well done. Thorough, well spoken, edited and useful. One question. Did you leave the key in the on position and engine off while waiting many minutes to see if pressure was holding??
Hello I have a question, so I have a 2008 can-am ds 450 efi . For some reason it Turn on and drives if I continue to give it gas . But as soon as I sit in one place for longer then 30 seconds it turns off , and keeps doing that , I thought it would be the fuel pump relay but I already change it and it’s doing the same thing can you help me out
im sure somebody did mentioned in these hundreds of comments which i have no time to read all, O-rings in modern in-tank fuel pump+filter+regulator, need to be changed as well to reduce/prevent gradual loss of fuel pressure over time and improve fuel pump efficiency(less workload in the long-run). sharing experiences is cool.
Oh my days, thank you for explaining this so clearly! I now feel encouraged to retrieve my car from the garage (what we call the mechanic's workshop in the UK) and carry out this work myself. I feel bad about them charging £210 for an hour of diagnostics, but more than that I feel bad for missing out on the opportunity to learn about the fuel delivery system.

Backhanded compliments are just the thing everyone likes to hear. Drew, you have a responsibility in society not to be a bully. To be taken to account when you are one. And to apologize if you realize you made a mistake. This would be akin to a person saying that someone’s hat is cool then pointing and laughing because they are blind. I hope you can understand how your words matter. If not, that’s okay. I have a great sense of humor… laughing at things like this are not funny.
@@rickbrower5794 I don’t understand why people get so offended/triggered over the smallest little things. Comparing him making an observation about his dialect to laughing at someone who is blind is a piss poor analogy. If he said something like “It’s pronounced “vehicle” not “vyhricle”, idiot.” Then that would be rude and completely unnecessary, but All the guy did was comment about an observation he made. He shouldn’t apologize nor does he have a need to. If you don’t like what he said cry about it and move on. Grow up.

I love you man, I know I'm a year late for saving my expedition but fuel pressure or the Fuel pump shat the bed. I had to keep my foot on pressed slightly on the gas, otherwise it would stall. It's last day with me, it stalled in traffic and thankfully I managed to steer into a side street with no power, everything just shut down so it required some strength to steer that beast. 1999 expedition with the V8 Triton engine. Lesson learned.
I learned a hack from a fellow youtuber earlier: if there is still pressure loss at the shrader valve with all fuel injector electrical pigtails unplugged there's a high probability that an injector is stuck open and leaking.
Wow, increíble information, i know it took so long to learn such thing, and making it to happen, I have learned alot watching, i made mistake but i enjoy doing it, i think this is my job field.

Great video and professional advice! If a dirty fuel filter under my car is going to create all sorts of driving issues and potentially make me spend lots of money later, I will change it with every oil change! Since my car will be jacked up anyway.
This is great you explain things in a easy to understand way so many people show so many different ways to do things and that gets people who are new to this confused thanks

Happy Thanks Giving and Happy Holidays 2023 -Sean Robert
Thanks for the video I have a 99 Ram 1500 with a random misfire and it has new spark plugs, spark plug wires and distributor cap so next I'm going to start checking the fuel system
Thanks for this video. I have a 2014 Silverado 3500 HD with dual tanks (gas) I've spent over 4k in the past 3 months to get it to run right, even $1400 at the dealer, and they even send me on my way not know how to fix it. I'm going to test out the fuel pressure and look into the pumps next. I've already replaced: knock sensors, all 8 injectors, all 8 coil pack plugs and wires, mass air flow sensor, tps sensor, o2 sensors, both cats. I was at a loss until this video.
This guy has legit taught me so much, I got a job in FL as a mechanic and I used some of his tips and made my boss look like a dumbass…. Len is very smart
@@tommyconner1467you in florida also ? I put a hoist and a cement slab in for my chevy truck projects , sometimes i need someone to bounce ideas off of ..no one around here likes to wrench ..so there all lost on this stuff when i talk to them , and im not to knowledgeable , just enough to get me in trouble 😂
The spark plug tip was grade A helpful. I am going to pull out my plugs and hope that is the issue. After all the videos I have watched and also the various sources of text-based information I feel I am starting to narrow down the issue I am having.
You may want to rethink ( turn the key to on position and the fuel pump should/will run unless the pump is bad ) some vehicles , the pump does not run in the key on position , the pump runs while the engine is cranking and the pump continues to run if the engine starts - 99 corolla for example . You can hook a fuel pressure gauge direct to the fuel tank to isolate a fuel problem in the tank , or hook the gauge into the whole fuel system , its best to check both ways , you can find out if you have a problem on one end of the system , or on both ends of the system , now , do what ever you want , its yours .................
So if fuel pressure is the issue- the simplest way to start is the fuel filter? Or just go straight to fuel pump? You are so good at dumbing this down for DYI’s like me. And it’s impressive that you can do it talking so fast. Great video
Idk how often y'all go back to old comments on old videos but working on a 98 lumina 3.1l. The car starts fine at first then dies out of no where. When it dies it doesn't want to start other than just continuous cranking. Fuel pressure drops about 10psi within 20 to 25seconds. The pressure regulator has suction when car is running. It primes up to 40 when key is turn to on position. I do hear clicking where the fuel injectors are but not sure if that's just what they do. My truck don't make that sound when just primed but her lumina does. had good vacuum n what not when car was running and pulles hose off of regulator. From what I was told the pressure regulator is activated via suction so when car is on. She's had new battery, new spark plugs and wires, fuel injectors, o2 sensor (one of em), gas cap, maf, and fuel filter replaced. Still same issue. Dies out of no where and doesn't want to start
Outstanding video !!! Informative and accurate. His explanation made absolute sense and covered the issues my car was having. Replacing the pressure regulator solved my problem. Thanks dude, you saved me losts of cash for a mechanic.
Ha just picked up my 96 Tahoe that had a leaking regulator. Had the shop change out the old central port fuel injector to the updated multi port interior since the regulator was on it(might as well right). Oh baby she drives great now.
Okay so I began the process of replacing my fuel filter. Following a video I removed my gas cap, started my vehicle, removed the fuel pump relay, and let it die out to relieve fuel pressure, disconnected my negative cable on battery and then I was interrupted for about 45 minutes. Replacing my filter had to be put on hold. I replaced my gas cap, reinserted relay, connected negative cable, turned key to on position, turned back to off position, waited for 20 seconds or so and then started vehicle. Started same as usual but then began to bog out idle high a few times I guess trying to stay on then idle began to decrease gradually. Just before idle needle reached 0 it paused there for barely a second and then vehicle shut off. Now vehicle will start but then just die right back out. Love your videos and trust your professional diagnosis. Need your help ASAP. This isn't only my personal vehicle it's also transportation for 4 members in household. Every job in jeopardy. Working on this all day and night until fixed. What do I do???
Wow GREAT video! loved every minute. Did not know any of this because never had an issue and i have been a Holley carburetor since 1977; about 4yrs ago i had a problem like this and i added and inline fuel pump and it solved the problem BUTT i know it is not proper; Thankx for this video because now i know what to basically look for on a problematic 1995 Blazer 4.3L engine
In my '87 Ford 5.0L, fuel pressure is relative to the intake manifold, so the gage reading (relative to atmosphere) will drop with engine running, and can vary at least 10 PSI as you blip the throttle. The fuel tank is flat and sloshes badly even when fuel level is low. The resulting weight transfer makes it much more difficult to manage (and more dangerous) than you would think, so I made an attachment for my floor jack that supports the tank more widely AND also keeps the jack itself from tipping over. This has come in handy for transmissions that like to roll off the jack.
This came just in time. My car that just got repaired won’t start and it’s not the starter.. and my beater vehicle stalls while I’m driving.. then takes forever to start again at times! FUEL PRESSURE/FUEL PUMP IS A REAL THING !
I like his great explanations about symptoms and his way of describing what the function of a particular part does. He also doesn't start jibber jabbing about crap that has nothing to do with the subject being discussed. I do wonder when a vehicle begins to be a older model. When he says older models the check engine light most likely will not come on concerning fuel issues. LOL! when is a human considered old so to speak. Are you old when you are 40, 60, or 70
I like your video. I have a Chevy s10 4.3 that has sit for 6 years with about 1/2 tank of fuel. I put a battery in it and filled it with fuel leaving the old fuel in it. Drove it about 100 miles and suddenly it lost power and stalled and run piss poor. Could only drive it about 5 miles an hour to get it home. Put about 5 cans of fuel cleaner and fuel booster with injector cleaner in it. Each day now I start it and let it run until it dies. Noticed the fuel pump makes a louder noise since this happened. It seems to run a little smoother each day. Hoping it will clear up in a week or so. Thanks for the video.
Len ! love your videos ! did my serpentine thanks to you piece of cake. now i have a stalling issue with my 2012 ram 1500 5.7....ive done the plugs, serpentine, throttle body cleaning, pcv valve...it stalls at the stop sign. the rpm dips below 6000 an it stalls. if i tap the gas pedal when it starts to dip, it wont stall. i hope i can avoid a fuel pump change. it had a trouble code po463 that went away with a fuel injection cleaning. next thing i will be doing is to check MAFS, MAPS, EGR VALVE, IAC
Same here but with a 2017 Kia Rio! Works perfectly then once it gets hot it starts to stall at stop signs. Or if I fill it up with gas it will stall- unless I start it while stomping on the gas lol
Len did good on the video however i felt that he couk have went more in depth with the fuel pressure gauge he ran through the demonstration to fast and i would have liked to see every step of him attacking the gauge and seeing the results overall he done a great job /// my question to him is how do i get the fuel pressure up to regulation on my Toyota sequoia 2003 to allow it to start ??
Awesome video and your awesome I changed the fuel pressure regulator on a 460 Ford on a class A motor home and it's still loosing power when I'm driving it and it will bog down and sputters but on park I can rev it up fine so I'm thinking now it's the catalytic converter or o2 sensors or fuel filter the air filter is fine or maybe the spark plugs which will be next the fuel pump is working fine too maybe the fuel injectors but I put injector cleaner so let's see what I find thanks my friend.
I have a 98 Jeep ZJ I just purchased with the 4.0 and this video has helped me tremendously on how to use a fuel gauge properly. I've purchased from you before with great results and will do the same if my pump turns out bad. Question: I found my fuel fill-up compartment is busted down at the bottom inside where the gas cap seats and the little flapper door is broken and pushed to the side...... I'm hoping that is the problem and i need to borrow my buddies fuel gauge. Hence this video is a big help. Thanks and Merry Christmas 🙂
Exactly what happened to my wife's Tahoe and what's happening to my camaro. I'm in the process of figuring out how to get the gas out of the tank because she filled it up before it stopped running. I'm also having stuttering in my Camaro on acceleration, and I have to turn the car on for 10 seconds before I push start it, or else (3 times outta 10) it won't start.
You are the man......I have an 2008 nissan pathfinder and I have somewhat the same issue. I turn the key and no prime for the fuel. I'm assuming it's the fuel pressure regulater. I've checked the fuel pump, relay and fuses and they're all good. Any ides are welcomed, but I'm replacing that fuel pressure regulater tomorrow.....wish me luck
I have these issues, made a video with my phone with a manometer cranking and my mechanic says replace the pump. But i think better also filter and pressure regulator then. Thanks a lot!
16:18 What would be the reason for the needle not smoothing out? You know everything else about the fuel system. Don't leave me hangin' with I'll have to continue with my diagnosis?
I pulled the fuel pump out of my 2002 Honda CRV. I sat the pump in a little bit of gas and turned the key. The fuel pump was pumping fuel but it was very weak flow. At the shredder valve there is nearly no pressure at all.
My 2010 GMC Sierra starts up but runs weak for a second. It's done this for a while. Never seen a code, but I'm positive live data would catch it. It also only happens when the truck sits for a while like the fuel is settling.
This is hard to watch . This guy is lit ! His movements, his speech patterns, his pupils . Lay off the speed my guy. And is it just me or did he almost throw up in his mouth between 9:02 and 9:03 ? " fuel pressure (gag) ok friends"
Great video!! I have a 08 5.3, torqstorm, all stock block, upgraded aeromotive 340 fuel pump and 80lb injectors. At times I'd have to bled my fuel rail to start my truck. Idk what's causing this.

Bro made the video speaking and with sign language 😂
Len ! love your videos ! did my serpentine thanks to you piece of cake. now i have a stalling issue with my 2012 ram 1500 5.7....ive done the plugs, serpentine, throttle body cleaning, pcv valve...it stalls at the stop sign. the rpm dips below 6000 an it stalls. if i tap the gas pedal when it starts to dip, it wont stall. i hope i can avoid a fuel pump change. it had a trouble code po463 that went away with a fuel injection cleaning. next thing i will be doing is to check MAFS, MAPS, EGR VALVE, IAC
Same here but with a 2017 Kia Rio! Works perfectly then once it gets hot it starts to stall at stop signs. Or if I fill it up with gas it will stall- unless I start it while stomping on the gas lol
Very detail. Great job on the explanation. Now I know what my problem might be.
Very good explanation and demonstration information about safety and DIY Thanks 👍👌🔧🙏💐

Len did good on the video however i felt that he couk have went more in depth with the fuel pressure gauge he ran through the demonstration to fast and i would have liked to see every step of him attacking the gauge and seeing the results overall he done a great job /// my question to him is how do i get the fuel pressure up to regulation on my Toyota sequoia 2003 to allow it to start ??
Awesome video and your awesome I changed the fuel pressure regulator on a 460 Ford on a class A motor home and it's still loosing power when I'm driving it and it will bog down and sputters but on park I can rev it up fine so I'm thinking now it's the catalytic converter or o2 sensors or fuel filter the air filter is fine or maybe the spark plugs which will be next the fuel pump is working fine too maybe the fuel injectors but I put injector cleaner so let's see what I find thanks my friend.
Excellent, excellent, EXHAUSTIVE video!
I have a 98 Jeep ZJ I just purchased with the 4.0 and this video has helped me tremendously on how to use a fuel gauge properly.
I've purchased from you before with great results and will do the same if my pump turns out bad.
Question: I found my fuel fill-up compartment is busted down at the bottom inside where the gas cap seats and the little flapper door is broken and pushed to the side...... I'm hoping that is the problem and i need to borrow my buddies fuel gauge. Hence this video is a big help.
Thanks and Merry Christmas 🙂
Thank You very much for an excellent presentation. This video is very well explained . The information is very usefull.

ran across u on accident but heard about u from another vid. U rock n I hope good on u. can't wait to work on my suv.. thx 😊
Love how u say vehicle wir thanx
Exactly what happened to my wife's Tahoe and what's happening to my camaro.
I'm in the process of figuring out how to get the gas out of the tank because she filled it up before it stopped running.
I'm also having stuttering in my Camaro on acceleration, and I have to turn the car on for 10 seconds before I push start it, or else (3 times outta 10) it won't start.
You are the man......I have an 2008 nissan pathfinder and I have somewhat the same issue. I turn the key and no prime for the fuel. I'm assuming it's the fuel pressure regulater. I've checked the fuel pump, relay and fuses and they're all good. Any ides are welcomed, but I'm replacing that fuel pressure regulater tomorrow.....wish me luck
Did it work?
I have these issues, made a video with my phone with a manometer cranking and my mechanic says replace the pump. But i think better also filter and pressure regulator then. Thanks a lot!
Good video and funny and learned 🤣 alot loved it but can't find a fuel pressure test port 🤬😡😠😭
Loose diesel injector seals will also cause low pressure, nip them up or replace if the engine has higher mileage or 10+ yrs old.
You're a star bro.
superb presentation. helps a lot of us regarding our cars

+Ydiscovered Ydiscovered Thanks for the feedback!
16:18 What would be the reason for the needle not smoothing out? You know everything else about the fuel system. Don't leave me hangin' with I'll have to continue with my diagnosis?
I pulled the fuel pump out of my 2002 Honda CRV. I sat the pump in a little bit of gas and turned the key. The fuel pump was pumping fuel but it was very weak flow. At the shredder valve there is nearly no pressure at all.
Pretty good display, thank you
very informative, complete and comprehensive. Thanks
Great video and presentation. I learned a lot
Great tutorial man. Thank you.
thanks for that information Len you have given me great hope
My 2010 GMC Sierra starts up but runs weak for a second. It's done this for a while. Never seen a code, but I'm positive live data would catch it. It also only happens when the truck sits for a while like the fuel is settling.
This is hard to watch . This guy is lit ! His movements, his speech patterns, his pupils . Lay off the speed my guy. And is it just me or did he almost throw up in his mouth between 9:02 and 9:03 ? " fuel pressure (gag) ok friends"
I appreciate your style, great info , thank you
Gosh, you’re such a genius tutor
Great video!! I have a 08 5.3, torqstorm, all stock block, upgraded aeromotive 340 fuel pump and 80lb injectors. At times I'd have to bled my fuel rail to start my truck. Idk what's causing this.
