Fuel pump
I believe my fuel pump is starting to weaken, looking for a replacement. Stock or Walbro 255 fuel pump for 2004 TL six speed with AEM v2 intake, ALTP J-Pipe, and ALTP base exhaust?

OEM, unless you plan on gaining HP.

Thank you! Nope this is as far as I will go. With all this traffic in the South Bay Area, additional HP will not help. Thanks again !!

What makes you think the pump is going bad? Have you replaced the relay yet? My car would randomly shut off when I was coming close to a stop/idle - 1 every 3 months or something. Replaced the relay, haven't had that issue happen again in 2 years. It's also much easier and cheaper to replace the relay than the pump.

my car can start, however I am getting P0171/ P0174. Running lean. Checked for vaccum leak, none. When the mechanic plug in the diagnostic, he said fuel pressure was low. No leak in the fuel line.

Could be either an issue with the o2 sensors. I'd still try replacing the fuel pump relay first rather than the whole pump itself, and then o2 sensors after that if still no improvement.

I just replaced the fuel pump assembly and drove 100 miles after install, so far no check engine light crossing my fingers though. I feel like this code has a lot of variation that it could be, so you could also be right.
I have also added a bottle of Chevron Tech Fuel Injector cleaner. |
Do you guys have the part number or any reference material for replacing the relay? I'm having missfire issues at higher throttle usage, and I don't imagine it's the relay, but I'd still like to do my due diligence of research.

I no longer own the vehicle, but it did fix the problem in this case
