EXCELLENT CHANNEL! Excellent info, especially for us non mechanics who are trying to diagnose and fix our cars when a REAL mechanic/garage can't! Priceless! Thank you!

If anyone wants to comment...I just had the fuel pump replaced when it failed and left me sitting, mid drive. But when I got my 03 Buick Rendezvous back from the shop, it now just cuts out while driving. (Like it's not getting gas) If I let off the gas when it starts to happen, many times it will recover without shutting off. If I'm going up a hill and I continue to try to get up the hill by lightly giving gas as its slowing down, it WILL backfire. I returned it to the garage because interior lights were coming on and off while driving all the while this continued, thinking maybe they crossed the wires on the fuel pump upon installation. (Now these symptoms only happen AFTER it is warmed up. Never happens cold. Well the mechanic said it was the wiring harness and apparently replaced that. They said it was fixed (no charge 🙂) Picked it back up and same symptoms continue. Spitting sputtering cutting out and shutting off. (Not the battery, but the engine, losing power steering and brakes if I can't get it to "recover" by fanning the gas, or throwing it into neutral and revving.) Now I'm thinking gas pressure sensor?
Any comments greatly appreciated!! Thanks yall, from this southern girl to....you? Lol)
I should add recently before this I had a different shop remove my catalytic convertor (without my permission!) When I took it in to have 02 sensors replaced. A week after that, the fuel pump went up and when I got it out of the garage, that's when these new symptoms appeared.
The adventure continues....🥴

Replacing bad fuel pump caused my regulator to go out, it was probably already on its way out. Thanks for the help.

Bingo! 2005 Ford Explorer V6 4.0L. Running fine one day and wouldn't stay running the next. Disco'd the MAF sensor (after cleaning it failed) and it started right up. R2'd and now it runs even smoother than before. Thanks!

[Alexmechanic]

Thanks brother. Im having all these symptoms on my 90 accord. Will try the fuel pressure regulator and drive the car

You left out an important one, when the regulator fails to go closed all the way it fails to maintain higher pressure during heavier fuel demand under load, resulting in loss of power.

Thank You, I don't know if this is the problem or one of the problems, but I really appreciate people like you sharing knowledge.🎉

I stumbled on this today and every sign matches my car🤣😭 for the past 3 months I've seen the gas station more than my parents 😅. I'm away from my car now but when I'm back I'll come back to this video if it works out to thank you. All the symptoms starting from poor fuel milage match my symptoms. By the way its a 4afe engine on an ae 110 1998 corolla

[davidbrady]

Great vid bro! Straight forward and easy to listen to production unlike 95% of car diagnostics videos lol

[JaxonThompson-uz]

Thank you so much, with a broken OBD plug, I couldn’t even be steered in the right direction, I knew it was fuel related when I smelled fuel heavy, truck just started doing this a week ago occasionally, but now it’s full blown misfire and puffing some smoke

[jaxondakota]

Bro thanks for this video, I have a p0175 code, I’ve been looking at multiple videos and all them dudes was way off. This the one right here!

[didalidang]

Well explains why I have put 2 sets of plugs and wires in my truck in the past 6 months. Don’t have to worry abt the cats tho. They’re in some junk yard somewhere😂 but I really appreciate this video tho. Wish I knew about this possible problem sooner!!

[RedwoodsNorCal]

Great video. Very informative, and polished production as well! I think mine is the reason for my current no-start condition. Fingers crossed 🤞

[williamb]

My sisters 08 Avalon had hard starting. TK changed the fuel pump...why they never replaced the FPR on the side of the pump...beats me.
TK said it's not the FPR.
Not getting anywhere with TK, I YouTubed and changed it myself....not that hard.
I replaced the FPR..problem solved.
Thanks to all those YouTubers out there !!!

[berad]

This video helped me very much is what I needed the information I was looking for on my 2002 Mitsubishi eclipse GT that's having a problem running it's not running right after I replaced the spark plugs and wires and changed the distributor Cap and still the same I never thought to look at the fuel regulator

[leonhilburn]

[davidwelday]
