I'm getting ready to fire up my '93 Z28, which has been apart for almost three years now, and as soon as I turn the ignition on it instantly blows the 15 amp ECM/IGN fuse. I have had the entire drive train out of the car, so there are probably only about 300 things it could be. Does anyone have any guidance on what to start checking in order to track down the problem? Thanks.

 

Was the 15 originally there? Try a bigger fuse then maybe.

 

Yes, it's a 15 amp fuse originally, so I assume it is 15 amp for a reason. I'm going to do some troubleshooting tonight.

 

I got the problem fixed, with the help of a 2003 post from Shoebox. It was my fuel pump relay. The relay has five prongs on it, and only four wires attach to it. I had my wires crossed up. Thanks for the help.
