FUEL INJECTOR (for Port Injection): Removal

  1. PRECAUTION 
    CAUTION:
    • Before working on the fuel system, disconnect the cable from the negative (-) battery terminal.
    • Do not smoke or be near an open flame when working on the fuel system.
    • Keep gasoline away from rubber or leather parts.
    • Do not allow fuel to spray when removing the pipe between the high pressure side fuel pump and the fuel injector. The fuel in the pipe is highly pressurized.
  2. DISCHARGE FUEL SYSTEM PRESSURE 
    CAUTION:
    • Do not disconnect any part of the fuel system until you have discharged the fuel system pressure.
    • Even after discharging the fuel pressure, place a piece of cloth or equivalent over fittings as you separate them to reduce the risk of fuel spray on yourself or in the engine compartment.
    1. Disconnect the fuel pump connector.
    2. After the engine has stopped on its own, turn the engine switch off.

      HINT:

      There is a possibility of DTC P0171/P0172 being set.

    3. Loosen the fuel tank cap, then discharge the pressure in the fuel tank completely.
