Default No power to fuel pump after motor / harness swap
Having trouble trying to figure this out, i've tested for power where the ecu plugs into the rest of the car's harness, it has power there, there is no humming from the BAC though and no power to the fuel pump, i'm not sure if maybe it's a grounding issue, but the main engine harness ground is bolted down.

i've tried changing out the ecu and it didnt change anything.

The car is an 87 gxl, i swapped the harness from an 86 base (both low impedance injector cars) into it since the original harness was damaged, i thought there was no real difference between the two but maybe i was wrong, the only other thing i can think is that maybe the ground ring terminal went bad, but i came here for any more suggestions.
