I have changed the fuel pump, fuel filter and ignition control module but my car still won't start. What else should I check to get my car running? I ran a On-Board Diagnostic Scan and the codes P052 History, A048 History and I052 History came up. It also said that I had no ACP Codes, SIR Codes and no PCM codes. I also had a PCM?. Could you tell me what these codes mean?[/quote:d14d1fc4df]
PO 52 is a PCM code, its an idle circuit code, TPS out of adjustment, AO 48 is an AC code, IO 52 is a body code I think
what kinda parts did you put in it? did you buy them frrom the dealer?
squirt carb cleaner down the throttle plates while someone tries to start it. does it start?
if not its your cam sensor( hall effect switch) or coil or pull peice, it is also in your distributor. you have to pull the distributor to replace it
the coil is in the top of your distributor cap, look for arcs around the black part of the coil
when you get it running I will tell you how to fix the PO 52 code
the AC probally only works in econ mode with the AO 48 in it,
