I'm swapping in an LS6 for the hurt LS2 (aluminum 5.3). All is going well except for the vehicle security system. The vehicle security light wont go out and I can't seem to disable it. I've disabled VATS as well as setting P1629, 30, 31 to No error reported.
I drove it into the shop. Every plug and ground is reconnected. I have tried to make it relearn the only key but I've had no luck.
I can't start it from the key at all. Starting from the the starter solenoid gives ~5sec of runtime.
Any advice or assistance is appreciated.
Thanks,
Mark
