ok so we have a problem we where wiring the stereo in a 7 and we cant make that work either but thats not the point we went to start the car and we arent getting ANYTHING no spark and no fuel, we changed the coil pack and the cpu (after taking out the main fuse in the power cord to the amp) still nothing. Any hints??

 

You didnt' short out a power lead installing the stereo and blow a fuse, did you?
