Fuel Pump

fuel tank, supplies
fuel pressure to the fuel injectors. The
PCM controls the fuel pump motor by controlling the
fuel pump relay. The fuel pump motor is supplied constant ignition voltage
whenever the
fuel pump relay is turned On. The
PCM turns On the fuel pump relay whenever the engine is running or for
2 seconds when the ignition is turned On and the engine is not running.
