[QUOTE="lucheski, post: 16028552, member: 45286"] Crank no start, no prime to fuel pumps. THe PCM/ECU is completely unresponsive. A locksmith came over and attempted to cut me a new key his tool displayed "No ECU found". SCT Handheld also displays codes "No vehicle attached to device " "ECM Unlock Fails" Bob Kurgan said if it was a only PATS issue the fuel pumps would still prime and it could be the PCM not sending signal to CCRM to prime the pumps. I set the cluster in self-diagnostic mode and pulled codes from instrument cluster and got code that said "Non-Volatile Memory (NVM) configuration failure - No PCM ID stored in PATS." Already checked EVERYTHING else. Fuses, Relays, Inertia switch, Pumps jump manually, Took apart CCRM tested relays inside individually. Even tried a new CCRM just to be certain.
