Question about 1995 Pontiac Grand Prix
I have a 95 Pontiac Grand Prix that died all of a sudden. I replaced all the camshaft and crankshaft sensors. I replaced the camshaft since it was snaped in half. I replaced the ignition coils, ignition controll module, the PCM and the map sensor. I double checked the camshaft and crankshaft timing. All the plugs and wires are still good. I still cant get the car to run right. I even replaced the injectors and fuel rail and wire harness. It seems like its still missing real bad and lacks power so much I cant take it on the road. What else am I missing that I should look at? All vacume lines are new.
CHECK THE FUEL PRESSURE A 3.1L ENGINE SHOULD BE 41 TO 47PSI. ALSO REMOVE THE VACUUM LINE FROM THE FUEL REGULATOR, START THE ENGINE AND WATCH FOR FUEL AT THE REGULATOR PORT.
DROP THE EXHAUST SYSTEM AT THE REAR OF THE ENGINE. TRY RUNNING IT DOWN THE ROAD A SHORT DISTANCE. IF EVERYTHING WORKS AS DESIGNED THE CATYLITIC CONVERTER IS PLUGGED.
