Locate the fuel pump relay and remove it. Insert a jumper wire into the relay socket for the secondary voltage to the fuel pump. Turn the ignition switch to the run position so that the dash lights come on. If the fuel pump doesn’t run, the problem is most likely with the fuel pump.

I forgot! There’s a quicker way to check the fuel pump!

Next to the brake master cylinder you’ll find an electrical connector with nothing plugged into it. This is the assembly line fuel pump prime wire. Just apply battery voltage to this wire and if the fuel pump doesn’t function replace the fuel pump.
