Fuel Pump

Fuel Pump:




The fuel pump motor, located inside the fuel tank, supplies fuel pressure to the fuel injectors. The PCM controls the fuel pump motor by controlling the fuel pump relay in the Left Instrument Panel Fuse Block (LIPFB). 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.
