Operation Check

  1. Turn the ignition switch to OFF.
  2. Apply battery voltage to the fuel pump drive connector to check that the pump operates.
    NOTE: The fuel pump is an in-tank type and its operating sound is hard to hear without removing the fuel tank cap.
  3. Pinch the fuel hose to check that fuel pressure is felt.
