Ok guys, I have 30 lb. of fuel on the fuel rail.. starts only with starting fluid.... I have 12 volts constant for the fuel injectors.. ?????????????????????????????????????????????????? ???????????????? Computer is new.. Injectors are new.... Puzzled....

 

12v constant on fuel injectors is the issue. You suppose to have square wave signal on injectors. I can't confirm is it should be 5v or 12v though. Are you 100% certain that PCM is the right one for your engine?

 

Just for kicks - connect old PCM with new injectors and see what happens.

 

Tried the old pcm and put a new pcm on it with the same issue... if i put a stethoscope on it you can hear the click that the injectors are opening and with 30 lb. on the fuel rail I am totally stumped.. I checked the schismatics on it and it should have 12 volts all the time and the negative side goes to the pcm...I D K... Thanks for any input....

 

Fuel pressure might be too low. On a 3.5l engine the spec is 47-50 PSI at idle

 

Not even a sputter... I can hear the injectors open with the steth but to no avail...

 

Next two items to check is spark and compression.
