Need to know what harness you have to say for sure, but this should get you started

This is the fuel pump relay for a 3rd gen f-body



Ignoring the majority of it, you see there's basically a 12V in and a 12V out to the fuel pump albeit mislabeled in the diagram (Relay failure not ECM)

Remove the relay and jumper the terminals; not being a 3rd gen the pins will not be the same, but the colors/functions should be if you are using a GM harness

Alternately you can use the test lead if your harness is equipped and you can locate it

R9 is the pin placement at the PCM
Red 9

Click means the relay is energized, your pump should engage. No sound = bad pump
