I have a 90 pickup that keeps blowing the EFI fuse everytime I try to start it. I've traced the wires and everyting and I got it running yesterday and then it cut off on me because my harmonic balance messed up and broke the belt so my battery went dead then I checked and the fuse blew again. Can you guys help me out a little bit?

You have a 3.0 v6? My solution was to run a new wire from my battery to the fuel pump and computer. Thats what that 15 amp efi fuse powers. And then I threw a relay in the mix so that the fuel pump and computer are turned off/on with the key. The hard part is finding a power source that isn't turned off when you start the truck.

Feel free to PM me for details.

Double check that the wires to the O2 sensore aren't burned thru over the exhaust.
