Best Answer

Turn the key to the on position without starting the engine, listen closely or have a helper listen to the rear driver's side, where the fuel tank is. When the key is turned then fuel pump comes on, making a slight whirring sound. If there is no sound at all or something more than a slight whirring sound, it's probably about time to replace it. Also, if it takes a long time cranking to turn over the pump may not be building pressure properly.
