You need a multi tester to find the problem , it may be a grounding problem . You could have bought a nice one for the money you spent on parts you didn't need , now you're back at square one , without a multi tester to find the problem . Fuses , relays , ignition , ground , who knows ? ? ?

Check the inertia switch, it could be tripped or have a bad connector. If that checks good and the wiring is fine then it’s most like the pump itself.

Idling in the driveway unattended? Maybe you just ran out of gas.
