Fuel pump relay receives voltage from circuit opening relay to operate the fuel pump. Fuel pump operating speed may be varied by the ECM. When ECM grounds fuel pump relay and relay contacts close, voltage is supplied through fuel pump resistor to the fuel pump. This changes fuel pump operating speed.
