It will be running fine, and then it just shuts off. Usually after it sits there for a day, it will start again. Thought it was fuel pump or pressure problem. It has a new fuel pump (not the one in tank...the other one), filter, and a new fuel control relay. The plugs are firing after it dies, its not ignition. The car has been with a very exerienced pro mechanic now for over 2 weeks, and he can't figure it out. NO codes are set. The mechanic says it still has fuel pressure when it dies. He pulled out one or more plugs, and said that they are soaked with gas, so he thinks the engine is flooding out. I didn't think this would happen with injected engines....it just dying like you switched off the ignition key.
If I remember right, this car has a separate fuel control (Jetronic) computer module. (or maybe I'm confusing with my 88 Camry?) Maybe if it is intmt. failing, the injectors would be stuck open, or open way too long, flooding the cylinders with gas? But there is no code being set for a faulty fuel ctrl computer. It costs big bucks to buy a new one, and then we might find its not that!
I don't know if the mechanic has put noid lights on the injectors when it has failed, that is what I'd do...and try reseating the ECM connector if the noid lights don't indicate a failure.
Ideas?
