Pontiac Problems? Ask a Mechanic for Answers ASAP
Hello Im Reggie, do you know what the car is lacking to start, fuel pressure, injector pulse, spark? the parts you have listed affect different systems. IF your not sure a spark tester to check spark at spark plugs, if you have or can rent at autozone a fuel pressure gauge your looking for around 40 psi, if no gauge take the line loose at engine put in empty bottle and spin over for 15 seconds, you need to see at least a half pint. If you have both of those next would check for injector pulse remove a connector from one of the injectors there are 2 wires one of which is hot with the ignition switch in the run position the other is a pulsed ground from pcm they sell noid lights you plug into the connector they blink when spinning the motor over, if they dont you have no pulse and engine will not start. I dont know your tool arsenal or experience level but whatever your intentions are im here to help
1. Using a lab scope, check the voltage level and injector pattern at the Powertrain Control Module (PCM) connector C2 pin 22 Pink/Black wire. If there is less than Battery Voltage (B+) with the key on engine not running, check the wiring from the #3 injector to the PCM pin 22 for opens and or shorts to ground.2. If the wire is good between the PCM and the injector but there was less than B+ at pin 22 of the PCM, check for B+ on the Pink wire at the #3 injector. If there is B+ at the Pink wire but still less than B+ at pin 22 and the wire is good between the two, the injector will need to be replaced.3. If there is full B+ at the PCM pin 22, start the engine and monitor the injector pattern. If the pattern is erratic or no pattern at pin 22, the PCM will need to be replaced.
You most likely have a bad injector shorting the quad driver out in the pcm take a voltmeter and check the resistance of each one look for around 13 ohms measure each one and any that are even slightly out of range replace it.
FuEl pressure resistor? Do you mean furl pressure regulator? So hAve to resolved your problem?
Are you talking about the control module? I'm only asking because therr is no fuel pressure resistor. Just want to make sure you get it fixed
Oh aftermarket so this fixed it
No sir I don't think so not for that code you have. Tell me about this 2 speed fuel pump who makes it and what is its advantage over factory
