I have been trouble shooting my Acclaim for the past three days. Here is what I have found:
Engine will crank but not start. Engine has good spark, compression and air.
I thought at first it was the fuel pump because the car would start right away when I spray quick start into throttle body and if you keep spraying it, it will continue to run. But I checked the fuel pump and it has good pressure. Fuel Filter is new and is not the problem because I checked the fuel pressure right up until it goes into the throttle body.
So I was thinking either the Fuel Regulator or the injectors? Or is there some sort of EFI module that could be bad?
I had driven the car the day before and everything was running fine. When I went to start the car in the morning for work (much milder day than usual) it almost started on first key turn and then would not start. Hasnt since.
Another thing I noticed is that when the engine is cranking a tiny bit of fuel is dripping out of the module that is directly over the hole in the throttle body. I am thinking this is some type of secondary injector? Maybe when the throttle is wide open? But it is not enough fuel dripping to start the engine. I have to spray quick start to get it to turn over. Not sure if this means anything or not but thought I would mention it.
Please let me know what I should check next as I really need to get this bad boy back on the road.
Really appreciate your help!
