It started out as trying to change the evap core in my son's car (05 Grand Prix GT) that ending futile. So we put the dash all back together and not I get the VATS triggered and can't get the car started. All connectors and grounds were proper. Only thing that is slightly off is the plastic guard on the ignition switch that the key goes into cracked off. None of the insides were effected. It's that ring that holds the face plate on.
I've tried disconnecting the battery and checked all fuses and it is the original key to the car.
Suggestions?
Also I have access to HP Tuners, if I disable the VAT codes will it let the car start?
