When I turn on the key, with no engine, I get about 10 psi.
When I start the engine, I'm running a consistent 24 psi.
Obviously this is far too little pressure.
So here are my next questions:
1. Is there a fuel pressure regulator on this car? It has only 1 line running to the fuel rail, and there is a fuel damper on the fuel rail. But that damper is NOT a regulator, is it?
2. Is the culprit likely my fuel pump?
3. Could this low fuel rail pressure be causing me to have a P0171 Code coming up (lean bank 1)?
I"m running an E8643 from Autozone. Same one would fit your car too. It was actually a Walbro pump in an Airtex box. Runs great and more than enough for a stock engine. I chose it as it should be enough form my car when I go to a bigger turbo and ARD tune. Already running bigger injectors and E85 mix. Autozone or Oreilly about 130 and 1 yr warranty.
I would also check out FCP to see if theirs would have a lifetime warranty if installed by an ASE tech and you were going to be hanging on to yours for a while.
The advise is FREE, you get what you pay for!
