I’m working on a 2005 cts with the 3.6. I just completed the engine swap and fuel pump won’t activate nor will starter engage and key gets stuck in ignition. When I first tried to start the car the dash display said traction control system and security or anti theft I can’t remember exactly but now the radio/display won’t come on at all and car still won’t do anything. I’ve read a few ways to disengage the anti theft system but nothing has worked. Any thoughts and ideas would be very much appreciated.
