    Have you checked the actual connector at the pump for battery voltage while a helper cranks the engine? Engine has to be cranking (turning) before power is supplied to the pump.

    Check for battery voltage and ground at the pump connector while someone cranks the engine! No inertia switch. Have you tested the pump with it out of the tank while the engine was turning over to see if the pump will run? You may not hear it running, hold on to it to see if you FEEL it running, again while engine is being cranked!! Post the results for more info.
