2000 Regal Wont Stay Running! 3.8 SC
The problem started the day I was driving during a heavy rain storm. Not sure if it was related or just a coincidence.
The engine just stopped running. I was able to restart but it will only run for a few seconds and stop. The following items have been changed or verified ok with good components.
Fuel pump - Changed
MAF sensor - Changed
Crank Shaft positioning sensor - Changed
Fuel pump relays Ė verified ok
With a fuel pressure gauge attached you can see the pressure go up to approximately 50 psi when the key is first turned on. As soon as you start the car the pressure drops and stalls.
There is two ways I can keep the engine running.
1. If I hold the accelerator pedal full throttle the pump runs building pressure and the engine stays running. The psi drops the moment I start to decelerate below the rev limiter.
2. I can make the car run normal by jumping across the normally closed contact (forcing it closed) on the fuel pump relay (spd cont), I think ití* labeled # 19.
I donít know where to go from here. Donít want to keep adding unnecessary parts.
Any advice would be appreciated.
