Most gm immoparts, need to made virgin, with the pin code.

You sound convinced, the data is gone.
Or the processor, is corrupted,

If you solder the processor back on, and connect diag wires, you could see if it is really erased.
You have a wire diagram, and if is used canbus, a 120.ohm resistor, between can h and l.
What diag tools do you have?

This Regals immoset, is it only reader + pcm.
You still need, the pin code.
Are there gm dealers, you could contact?
Request pin code, and buy new ignition immo unit from?

You could look for a full immoset.
Find out, where the pcm is located, and let them take a picture.

Google vats and you will find this on ebay:
VATS Anti-theft Delete PCM Service: 96-05 Chevy, Buick, Olds, Pontiac 3.1L, 3.8L
