I have a 97 Pontiac GTP which is not turning on. I have checked and I know I have a nice strong spark, fuel pump is on and fuel pressure is on the fuel rail. I know there is 12V at the fuel injectors but when using a noid light I know that it is not getting a pulse and is not allowing any current to flow in the line. I checked all obivous fuses and so forth.
Is this a sign of a bad computer? Or are there other pieces that if not working properly will cause the computer to not send out a fuel injector command? Could the Cam position sensor cause this?
Thanks for any help you can give!
I think the cam sensor mainly provides the base ignition timing signal. Put a code scanner on the car (some parts places will do this free of charge) and get a list of trouble codes the ECM is throwing. This will help find a starting point.
in the mean time, check the wiring harness between the ECM and fuel injectors and checl the ECM and make sure ALL of the grounds are in place.
