We are now at the opposite end of the problem we were at before. We now have TOO MUCH gas going thru the rail, it is flooding itself out. Fuel pressure is PERFECT, but for some reason why to much fuel is going thru and cause the car not to start. The plugs are full of fuel, the injectors OHM out normal at 16. Wondering if we should check the injectors first or replace the ECM again?

Thank You

What does your fuel pressure do when you shut the key off?
Is the check engine light on?

I didn't ask if the fuel pressure was normal. I asked what it does when it's shut off.

Does the pressure hold after the key is shut off or does it drop off?
