Probe Fuse engine 2 blowing?

I have a 1990 Ford Probe 4 cyl. non-turbo with what started out to be a battery problem. The negative battery cable was loose, and I am assuming that the battery was arching. Which in turn I think had blown my fuel pump - I had replaced the pump and also the negative cable. Now when I start the car, it runs for about 5 seconds and kills immediately. The reason it kills is always the "engine 2" fuse in the fuse block inside the vehicle has blown. I can replace this fuse, but the same thing happens again. Any suggestions or ideas?

My guess is the battery may have fried something else, wires, relays, anything that's causing it to short out and blow the fuse.

I have traced the entire wiring harness, and the only concern I had found was one wire which goes into the fuel pump assembly. The wire had sections where the insulation was worn off - bare wires. I spliced a new piece of wire in the placeof the bad section, but I am still having the same problem as described earlier.

Also does anyone know how to test relays and and in-line fuses? Any help on this would be greatly appreciated. I then could continue to trouble shoot the wiring.

Thank you,
Tim
