Swap Wiring help

[xLeGeNDx]

so i decided to swap in a 1990 3.1L into my 92' GP the engine came from a 1990 GP STE, so i used the complete INTERIOR and ENGINE harnesses from the STE as well.

now the problem is the STE started and ran fine but after the transplant into the 92 i got it to start for like 3 seconds then blew the FUEL PUMP/ECM fuse, and everytime i put a new fuse in it blows the second i turn the key to the ON position. any idea where to start tracking this down at?

or maybe a wiring diagram that shows where the Fuel pump/ecm fuse for a 1990 sedan is ran?

I have used both the interior harness (even all the trunk wiring), the engine harness, the engines injector harness, and the forward light harness too

it could be a bad pump or a short on the injector harness. the injectors and pump r on the same fuse. its tuff because since u cahanged everything it could be anything.

i checked over the harnesses and they were fine to begin with i dont seewhat would cause this seeing that EVERYTHING was drug over from the donar car and wired the exact same.

bad pump?

isolate problem

disconnect pump, change fuse, if it blows not pump.
disconnect injectors, do same. yuo need to isolate the overload.
