When I bought this car it already had an after market stereo that worked fine. The factory sub was no good so I put a different sub in and an amp which I have done hundreds of times. Well when I got done installing this in my car would not start. I pulled a series of codes off the dash, but do not know what to do to fix it. Please help my wife is growing more angry at me and I fear it will not end well for me if it is not fixed soon.

Lol, yep, we better get it fixed then. Can I ask if the security light is flashing on the dash? If so follow this guide to reset the alarm. Also, can you hear the pump in the tank prime for five seconds when the key is turned to the on position without cranking the engine over?
