i just installed a new system in my 2000 buick century today. the car worked fine this morning, and as i tested it.. when i went to start the car to pull it out of the garage, the car wont start and the radio wont turn on.. i am thinkin it might be the immobilizer, if it has one... please help..
I think you have a short, disconnect the battery and check it. You need to go over you're wiring closely. Leave the system disconnected and see if you have a problem(you'll have to jump start i imagine)
