Welcome to the forum.
Check the fuel pressure w/ the key on, engine off. |
What should the fuel pressure be?

Somewhere in the 50-60 psi range

Fuel pressure checked 42 and blead off to 20 within about 5 min. So I replaced the fuel pump and strainer still same condition? Same fuel pressure and bleed. Any other ideas as what it could be? Driving me crazy.:mad:

Need three things to run, fuel, air, and spark. You are lacking one or more of these.
Any DTCs? |

I have read where the Optispark is the weak link on that model. It was subject to failure due to water getting into it. it sounds like it might be time to replace it.

Could be your fuel pressure regulator. I believe it's on the rail. It has a diaphragm in it and could be leaking.
