What powers the fuel pump?

The fuel pump relay is what turns on the fuel pump when you start your car and powers it down when you shut off the ignition. The engine control module (ECM) uses the fuel pump relay to control when the fuel pump is on. The fuel pump relay supplies electricity to power up and power down the fuel pump.

Is the fuel pump OK?

Though electrical components (such as a fuel pump) can spark and ignite fuel vapors, liquid fuel will not explode (see flammability limit) and therefore submerging the pump in the tank is one of the safest places to put it.
