My 2002 Oldsmobile Alero stalled and will not restart. it seems to have fuel pressure. I have changed the ignition module and checked all the fuses. there was never a service engine soon light or a security light even though i have done the procedures to correct the security light problems. It will crank and have a weak misfire once in a great while. I have been looking for the location of the PCM so i can check the voltages and the throttle sensor but am unable to locate it. I believe it might be around the steering column area. Any assistants woud be a great help.
REPLY: Yes, the PCM is located under the drivers side of the dash. It is an aluminum module with 2 electrical connectors. To be sure you have fuel pressure you would need to install a pressure gauge on the fuel rail tap. Also need to check for spark at a plugs and use a fuel injector test light to verify the injectors are being pulsed on.
