ok i installed the racetronix pump and everythings was good. i ran it with the factory wiring for a few days and the got the harness in and inastalled it..as soon as i turn the key on it blows the fuse..i know its not the pump because i hooked it back up to the GM wiring today and she was fine.i played with the racetronix wiring and if i disconnect the ground its fine but as soon as i connect the ground and turn the key on..pop..the fuse blows..what the hell could it be? i ohmed out the wire going to the alternator and its not showing any thing out of the ordinary ..please help
