Fuel Pump Operation Check

  1. Turn the ignition switch OFF.
  2. Using the Hi-scan (Pro)'s actuator test mode for fuel pump, check that pump operation.
    NOTE: The fuel pump is an in-tank type and its operation is hard to hear without removing the fuel tank cap.
  3. Pinch the hose to check that fuel pressure is felt.
