In an emergency I have tapped into the harness under the rt rear seat and stolen power for my fuel pump from my tail light circuit.

Pretty sure the pump only receives voltage when the distributor is turning. No turnee then no voltage.
Remove distributor cap and see if the rotor turns when someone else cranks the engine.

If it has a carb, this advice won't work.
If has fuel injection, connect the green diagnostic plugs.
If its SPFI/TBI, the two plugs are near the d/s strut tower at the firewall.
If its MPFI, the two plugs are under the dash. Pull the kick panel off and find them.
They're two disconnected green plugs with one wire each. Connect them together, and turn the key to ON. You should hear the pump cycle on and off. If not, then there is definitely something wrong with the wiring to the pump or possibly the ECU.

Only has the single pump. All the relays are literally behind the instrument panel. The ECU completes the circuit (makes the ground). Guess you could always run a hot wire to the pump. If still a no-go, run the other wire to ground. Checking for trouble codes is an excellent idea.
The distributor turns. I swear I can't get a voltage off the fuel pump. The fuse is good. Is there another pump in the tank? What else should I be looking for.
