I did the same thing aux wire from ign cylinder wire accidently sparked it trying to hook up radio now my car won't start changed the BCM and still nothing tried the relearn procedure and theft light stays on and won't say a thing what did you do after you accidently sparked the wire connected to your ign wire

 

Just wanted to share that I finally got around to replace the BCM on 03 monte by doing so got my stock radio back and air bag light went off. I did purchased a new Ac Delco BCM and did the programming myself with a Chinese knock off Tech2. The programming it self it is very much straight forward but what took the longest was the key relearned process which you do the attempt to start wait 10 min and redo 3 times until car starts again. One thing I learned is that yes you can get a used BCM but your radio and airbags wont work and if you get a new one make sure you know someone with a GM tech2 scanner because the dealer will charge too much money for programming
