2001 Ford Expedition fuses or relays

I was replacing a passenger side mirror. I was also replacing a window regulator. I did not unhook the battery. I had the radio on and somewhere in the process the radio went out and the car will not start. There is a taping in the audio relay and the powertrain control module. I replaced both and still won't start. When I turn the ignition on the radio and other circuits work for a bit then shut off. Everyone once in a while the engine will crank once or twice and shut off
