What happened to the fuseable link that it needed to be replaced?
If the fuseable link was blown there is excessive amperage in the circuit.
Was this the problem that was present and why you replaced the pump or did this happen after the fact.
The fuel pump is only 2 wires.A power feed from the ASD relay and an external ground.
The output of the ASD is a DG/BK wire to the fuel pump,+ coil ,fuel injectors and HO2S.
One of the things you need to check is the wiring for the HO2S behind the engine to be sure the harness is not damaged.
