I just replaced my fuel pump around 6 months ago and it has worked fine except last week it failed. I suspect the pump is good, what else is in the circuit (relay's, fuses etc) and where are they located
I am not sure about the 93 but in 94 there is a constant control relay located near the air filter. This box includes a fuel pump relay. Pin numbers 5 and 11 from the lower left are for the fuel pump relay in a 97. I would se if you getting power there from the relay to the fuel pump.
If the relay output does not have power check the input.
