Re: PO171 and PO174
Key on, engine not running, fuel pressure should be 55-60 lbs
Turn key off and fuel pressure should not drop by more than 5lbs...
25 to 30 running is way too low....its a wonder it runs at all...
Sounds like a bad fuel [pump or bad fuel pressure sensor....my money is on the fuel pump...
