Problem with vehicle stock wiring

I was putting an Eclipse Cd player into my 96 civic LX. I had everything hooked up and double checked, but the Cd player wasnt even getting power. So to see if the CD player or aftermarket wire harness was bad, i put the stock radio back in, and still nothing. Could something have happened to the car's wire harness that would cause it not to work?

possibly shorted out one of your fuses...
