Hi, I did research this in the manual, there is bus communication (SCP bus) between the PATS module and PCM.. I checked that neither bus line was grounded.. thanks for the suggestions...
Yea, the code stuff is good for every one. You are definitely heading somewhere... hopefully down the right track. Yes if the light goes on and stays solid (check engine), then powering and "base sanity" of the PCM is good. I would give my suggestion about the heating of the connector areas a try to see if it changes the symptoms a bit. I don't know much about the signalling between the PCM and theft module but it is probably simple as in the theft module throws on a ground and the PCM "replies" with a voltage.... probably not much more than that but I don't know and my 96 doesn't have the option.
