If your fuel pump is not receiving power it could be because a fusible link or fuse has blown, the fuel pump relay is not switching or the brain (ecu) is not triggering the fuel pump relay. To test it, pull the fuel pump relay and locate the coil prong and switch prongs on the relay. There is usually a diagram on the relay or the prongs are numbered. Prongs 85 and 86 are for the coil and prongs 30 and 87 are for the switch. Figure out ( carefully ) wich leads on the relay mount correspond with the prongs on the relay. Use a jumper between the switch leads ( 30 and 87 ) and have a friend stand by the fuel tank. Turn the ignition key to the on position and your friend should hear the fuel pump start to run. Don't run the pump for more than a few seconds. If it does not come on you have probably blown a fusible link or fuse. Remember to remove the jumper. If it does come on test the signal from your brain by using a volt meter or test light between the coil leads ( 85 and 86 ) on the relay mount. Have your friend turn the ignition key to the on position and the light should light up ( or the volt meter should show voltage ) for a few seconds then shut off. If this does not happen there is no signal from your ecu. If it does happen replace the relay.
