got any aftermarket electronics, like a stareo or remote start?
If so, remove any non factory wiring from the stock harness, and unplug anything that did not come from GM,. and let it restore the backup.
Thanks

we would have gladly picked that PCM up and repaired it for you, it certainly did not need to be replaced.
Fax us proof of the pcm replacement and give us a call within an hour or so with the tool powered up so we can unlock it for you.
