not sure what engine you asking about,but some oil pumps run off a lobe on the cam and dont rotate but pump same as a fuel pump. others run off a shaft that attaches to a gear on the crank.
No, the fuel pump relay engages and sends voltage to the fuel pump. The fuel pump requires 12 V DC to operate properly. A fuel pressure test will verify the condition of the fuel pump.
FOR TESTING PURPOSES ONLY you can jump the fuel pump relay to operate the fuel pump. If the pump is not running, knowing GM fuel pumps, it is probably a faulty fuel pump.
No, there is no way to operate a mechanical pump on your engine.
The fuel pump basically does what the name implies. It picks up fuel in the tank and pumps it from the fuel tank through a fuel filter to the engine. The pump is set to operate at a certain pressure that is needed for the application.

The fuel pump on a 1979 Ford F250 is located on the side of the engine. It uses a mechanical rod to operate the pump directly from the vehicle's cam shaft.
The fuel pump is located inside the fuel tank. Easy to change if you can operate a jack & have 15mm socket/ratchet, & needle nose plyers
to coat burner parts with diesel fuel and evacuate fuel from the fuel pump
If it has the 4100 motor, then the fuel pump is in the gas tank, be very careful when removing and installing, because if not properly ground, the fuel indicator and the engine will not operate correctly
All standard factory installed electrical devices operate on 12 volts.
Should be 12 volts, check the fuel pump relay and clean the ground wire to the fuel pump. In fact clean all the ground connections on the vehicle.
The fuel pump relay is a switch that let's a very small wire from a cars computer operate a component such as a fan or fuel pump that takes way more current than the small trigger wire could handle.
