Google says this could be the reason for my Tahoe having high fuel smell. Thanks for this video. Its a cheap enough part to try first.
I"m getting a P0300 and P0440. Thanks for you help. Wish I could've troubleshot this earlier but was focusing on the P0300 and costed me a pretty penny.
How’d you get rid of the p0300? I’m having that problem now.
Yes details please please??
neede in the haystack..check all grounds check plugs coils wires .@budthechud3408
I replaced mine. It makes such a difference.
2001 5.3 Tahoe 170K.
I have a code P0300 with multiple misfires on different cylinders. It started shortly after I pump a full tank of gas. It made me think that there was something wrong with the gasoline, but I have never had problems using different types of gasoline in the past. I have newer spark plugs and coils buy I check every single part that could potentially cause a misfire including all sensors. I was ready to bring it to the shop when I saw fuel coming out of the vacuum line that connects to the fuel pressure regulator. The hose elbow is cracked. I have ordered an original part. I will report back as soon as I install it. Thank you for your video.
Any update?
I will say this, I replaced with exact part and plastic white ring broke and made it leak gas. Got another one same brand and didn’t have white ring. Wasn’t sure about it. But used it anyway and so far so good. Would recommend taking the white ring off.
Video helps alot
replaced my fuel pressure regulator 2004 gmc yukon xl flex.. cleared code.. runs excellent.. thanks man..
That vacuum line was cracked but I'm going to change the whole part good video
Bro would can this part cause a rough start?
Yes it can
Very helpful video thanks
Could this possibly be the reason for my multiple misfire code? Just came up after I replaced the fuel filter.
A fuel pressure regulator works to maintain proper and consistent pressure for the injectors during a variety of driving conditions. Pressure that is too high can cause misfiring and increase vehicle emissions. Low pressure can cause poor vehicle performance and slow - or no - starts.
Could this be causing my Tahoe to spit the gas back out when filling her up? Already disconnected the evap system and blew through the breather hose as well and I still can't pump $1
Is the C5 Corvette filter/regulator a compatible upgrade for this type of fuel system? Any change to the fuel rail?
Excellent video helped me fix my problem!
If you don’t mind explaining, What was the problem you were having?
@@alvaromedina8061 I was having a hard start problem
@@jeffreybellows5051 I’ve been having the same problem for a long time. I think I’m going to buy the part and replace it this weekend to see if it helps. Thank you !
@@alvaromedina8061did it fix? I have extended crank issue, but if i cycle the key it will start up fine
@@gsd5.785 unfortunately it didn’t work. I bought the part and took the engine cover off just to find out that my 2005 Yukon XL does not have the fuel pressure regulator on that fuel line. It’s actually in my fuel pump assembly. I’m sure it would have worked though. Now it’s time to replace the fuel pump assembly all together.
This guy explained it pretty good ruclips.net/video/6RKdOu4dylM/видео.htmlsi=Ann4xJHYu-LyuOQB
Thank you for your time and showing
I get a p0308 code on my 2002.tahoe Indicating problem on cyl 8. I replaced the spark plugs and wires and coil on number 8 but code still there. Thinking about replacing the injector. Could this be the culprit?
Since you already eliminated the spark plug and coil the only thing left would be a bad fuel injector or loss of compression. Unless there’s an issue with the new coil but most likely not. You could always swap coil with another one and see if the misfire moves with that coil. But if I were you I’d try a new injector.
@@BLUECOLLARGARAGE you don't think it's the fuel pressure regulator then? There's also a gas odor and sometimes cranks for longer to start
@@Sam_DaManyeah sounds more like an issue with the fuel injector especially if your smelling fuel odor and if it takes longer to start the injector could be stuck open causing a flooding issue making it harder to start. Have you tried a good over the counter fuel injector cleaner?
@@BLUECOLLARGARAGE no. I just bought the car yesterday, I'll figure it out. Thanks
Hey bud I replaced the injector and it didn't fix it, what would be the next thing to do?
Great vid thank for the help!!
Great video thanks
What is the box right next to the regulator called? The one with the screw. My truck leaks from there.
Fuel rail
Why the ignition turn three times? And what fuel pressure should I see on a 5.3L Flex fuel engine? Having some issues after injector replacements.
Could this be the reason mine won’t crank at the moment? It turns off on me one day once I came to a stop and the clamp was loose
Just changed mine if the vacuum line had a small crack should I replace it too
I would so you get the correct vacuum on it. If it’s a very small crack you could also try and seal it with some super glue.
Thank you very helpful
First thing in morning it’s hard to start. But once started I can turn it off and does fine rest of day. But next morning same thing ..
That sounds like an issue with your check valve which is built into the fuel pump. GM vehicles are notorious for the check valves going bad. The check valve is supposed hold the fuel pressure with the engine off so what’s happening is it slowly drains that fuel back into the tank overnight. Only way to fix that is by replacing the fuel pump. If your interested I did do a video on this as well ruclips.net/video/KrcL0LXOjJY/видео.htmlsi=4iCY3K0eNYSkKYPi
I have a 99 yukon denali that has the spider injection ports inside the manifold. Where would i find the fuel pressure regulator?
Assuming you have the 5.7L unfortunately it’s not as easy as the 5.3 in the video. It is located underneath the upper intake manifold which requires removal of that and also draining the cooling system. And unfortunately I don’t have a video on that right now.
@BLUECOLLARGARAGE it is the 5.7. Everything is inside the manifold. Drat.
Can you re use the clip or I have to replace it
You can reuse it as long as it’s not bent.
Does replacing this regulator help reduce fuel consumption? Please reply
No this will not increase fuel milage
Can someone explain why my Tahoe 2004 has trouble staring but when I press the gas pedal and turn the key it starts up
When this happen were your rpm revving high into the 6000s while driving..?? Mines accelerates slowly gains speed but feels either sluggish or like it needs air I doubt its my tranny?
No issues with rpms. It was having issues with starting sometimes and had a miss ended up being the fuel pump that was the issues. Have you checked your fuel pressure at all?
THESE come preadjusted already? What symptoms your tahoe had prior?
Yes no adjustment. This Tahoe was cutting out sometimes while driving but ended up being a bad fuel pump.
Thank you so much
My 03 avalanche has no flex fuel badges or gas cap or anything but for some reason the flex fuel regulator is on it did someone replace it with thee wrong one?
Helpful. Thank you
How can I test this sensor? To see if its bad?
Thanks
Problem fix , by 12/1/24 the part cost me $ 104 with taxas , thanks sir
You are welcome
I hope this solves my issue. Fuel pressure won’t hold,hard to start .
If your losing fuel pressure after shutting off most likely the check valve is bad in your fuel pump.
Did it? I’m going to replace mine and see if it fixes.
My vacuum hose is cracked …should I replace that b4 replacing fuel pressure regulator???
Do both together
Nothing comes outta my shreader valve
Easy as 123
Did exactly the same thing. Leaks like a sob.. put the old one back..still leaks..wth
Did you make sure the snap ring is fully seated?
@@BLUECOLLARGARAGE I’m seeing 2 different kinds for the same 2002. The original one the nipple comes straight out as the new one
@@zman5970 the one in my video is a flex fuel so the vacuum line nipple comes out middle of the regulator and the non flex fuel vehicles it the nipple will come off the bottom of the regulator. The snap ring I was referring to is more of a clip I guess, it’s the one that keeps the regulator tight against the fuel rail just make sure that’s snapped all the way in the grooves and and is facing the right way. May want to just pull it out again and double check the o rings to make sure there’s no tears and they are not getting pinched.
🤠👍💯
Got mine for 10.00 off ebay.....:-)
Great video but the kind of part was killing me every second you kind of hold it kind of put this here kind of do this kind of do that either you do or you don't. I just don't understand the whole kind of part
I’ll kind of keep that in mind next time
I saw u u had the lock on the dash but it still start how did you bypass
Thanks
Thanks
