MUMBAI,
California
Recently finished by 6 bolt 2.4 swap in a 91 talon. Fresh motor. Ecmlink v3 speed density, walboro 255(not rewired) for electrically related mods. Wideband and boost gauge wires ran, grounds hooked up but no power to them yet.

The issue is when I went to crank it, fuel pump didn't prime or turn on when cranking. Previously i tried to turn it on in Link with no luck. Then after a few attempts at cranking, it popped the ignition fuse. Pulled the fuel pump to make sure everything was square, it was. And I ran power straight to it and it turned on. I jumpered the blown fuse to test some things and the mpi relay seems to be good, even swapped it out for a known working unit. Playing with some settings in Link I randomly turned off an injector, and the fuel pump kicked on. Very strange to me.
Further testing reveals excessive current when the key is in the on position, not acc or off. It maxes out my multimeter and it gets very hot very quickly. I'm getting 12v at the connector at the fuel pump.
Seems to me there's a short somewhere, what are some common things that could be shorted? Previous experience with this weird issue? Strategic approach to diagnosing this? Any help would be greatly appreciated, and pm's might be in order due to the nature of this beast.
