Fuel Pump Electrical Circuit Diagnosis Fuel Pump Electrical Circuit Diagnosis. Circuit Description. When the ignition switch is ON, the PCM activates the in tank fuel pump. The fuel pump remains ON as long as the PCM receives reference pulses from the ignition system. If there are no reference pulses, the PCM turns the fuel pump OFF after about 2 3 seconds. How does electric fuel pump work? Quora Answer Wiki. The motor inside the pump starts to spin and runs for a few seconds to build pressure in the fuel system. A timer in the PCM limits how long the pump will run until the engine starts. Fuel is drawn into the pumpthrough an inlet tube and mesh filter sock (which helps keep rust and dirt out of the pump).
