I have a 94 Camaro with the 3.4 and when we drained the oil it was mostly gas. The car wont start and when we can get it to it wont rev at all. If you turn the key on without trying to start it the injectors will continuously pulse. Please help i cant figure it out. Would it be the ECM

 

that's strange, check fuel pressure. pressure regulator may be failing and upping pressure so high injectors fail. did you get a noid light and make sure the injectors are being told to fire?

 

The fuel pressure when key is turned on is 45 but as the injector pulses it drops. It stays around 45 while cranking. I have not tried a noid light I will get one and try it.

 

this is really weird, have not heard of this happening before. if pressure is doing that I would assume they are being told to fire. I would be thinking what you are, ecm/pcm is not happy. I would test temp sensor to see if its telling ecm that is -40 degrees it may do what you are seeing, dumping mass fuel to start but from what you say its doing it before you even his the starter.

 

i am pretty sure i have narrowed it down to the pcm or the crankshaft position sensor. i did hook up a noid light and it has a slow but steady flash with key just turned on. when try to crank it it blinks fast for a sec then goes back to the slow and steady flash. the bad news we can not find a crankshaft position sensor anywhere. this car has two diff ones. a 2 wire in the back feeds the coils and the 3 wire in the front. we can find the 2 wire everywhere but cant find the 3 wire anywhere.

 

There are 2 crankshaft position sensors, and 1 camshaft position sensor, that the PCM uses to time the spark and injectors.

Sensor location:
3x CKS - right side of block at midpoint of crankshaft
24x CKS - on front cover, behind harmonic damper
Cam Pos sensor, top rear of block

 

yes and the 24x was broken physically. we can not locate one for nothing. i have tried everywhere around me.
