air leak

[steve]

Did you check fuel pressure? Are you getting a CEL? You really need to get a logger and pull codes. The lack of acceleration sounds like "limp mode". /ubbthreads/images/graemlins/dunno.gif

 

Quoting LordAthey:
we did get the pressure test and it was only at 15 psi.



sounds low to me. Was that before or after the FPR?

 

[LordAthey]

I know I get paid this week but out of town for the next week. If anyone has a datalogger for sale could you let me know. It was before the FPR by the way.

Only 15psi fuel pressure? Dang, I think that's the problem right there.

 

[LordAthey]

Yea so I'm not sure if it's the fuel filter, the fuel pump, or the ecu. Guess I'm going to replace one at a time.

 

[Barnes]

If your pressure is low, it is either the pump or the filter. Try the filter first because it is cheap and easy. Then check to make sure the fuel pump is installed correctly. You could be leaking fuel inside the tank; by that I mean you have a leak between the pump and the pipe that leaves the gas tank.

k well when I get time to replace the fuel filter I will let you guys know what happened. I will try and keep you guys updated.

 

you probably know this, but........ the filter is the cheapest and easiest. I kind of doubt that is the problem, but i guess its worth the 10 bones even if it doesn't fix it. Maybe borrow an ECU if you can get your hands on one and see if that makes it any better.

 

[LordAthey]

Going to order a datalogging kit tomorrow. I will let you guys know the codes when I get the kit.

 

[LordAthey]

I had sometime and replaced the ecu, but that didnt help it keeps doing the same thing.

 

[Barnes]

Have you checked the fuel pressure yet???

 

[LordAthey]

yea its only at like 25 psi before the rail

 

[LordAthey]

Ok so on saturday going to get a ob1 reader and read the codes on the ECU update you guys on what the codes are on saturday when I find out.
