FUEL INJECTOR(for Port Injection) INSTALLATION

PROCEDURE


  1. INSTALL FUEL INJECTOR ASSEMBLY

    Tech Tips

    Perform "Inspection After Repair" after replacing a fuel injector assembly.



    1. for Bank 1:


      1. Apply a light coat of spindle oil or gasoline to 3 new O-rings, and install 1 to each fuel injector assembly.

        Note

        Check that there is no damage or foreign matter on the groove of the fuel injector assembly when installing the O-ring to each fuel injector assembly.

      2. Connect the 3 fuel injector assembly connectors.

        *a Stopper

        Install the 3 fuel injector assemblies to the fuel delivery pipe with sensor assembly.

        Note


        • Make sure that the fuel injector assembly is located within the stopper as shown in the illustration.

        • Check that the fuel injector assembly installation holes of the fuel delivery pipe with sensor assembly are not damaged and are free of foreign matter.

        • Make sure that the O-ring is not damaged, twisted or moved out of place when installing the fuel injector assembly.

    2. for Bank 2:


      1. Apply a light coat of spindle oil or gasoline to 3 new O-rings, and install 1 to each fuel injector assembly.

        Note

        Check that there is no damage or foreign matter on the groove of the fuel injector assembly when installing the O-ring to each fuel injector assembly.

      2. Connect the 3 fuel injector assembly connectors.

      3. B0073HJC01
        *a Stopper

        Install the 3 fuel injector assemblies to the fuel delivery pipe with sensor assembly.

        Note


        • Make sure that the fuel injector assembly is located within the stopper as shown in the illustration.

        • Check that the fuel injector assembly installation holes of the fuel delivery pipe with sensor assembly are not damaged and are free of foreign matter.

        • Make sure that the O-ring is not damaged, twisted or moved out of place when installing the fuel injector assembly.

  2. INSTALL FUEL DELIVERY PIPE WITH SENSOR ASSEMBLY

    Note


    • Do not remove the fuel pressure sensor from the fuel delivery pipe with sensor assembly.

    • If the fuel pressure sensor is removed, replace the fuel pressure sensor (fuel delivery pipe with sensor assembly) with a new one.


    1. Install 6 new injection vibration insulators to the intake manifold.

    2. Install the 4 No. 1 delivery pipe spacers to the intake manifold.

    3. Install the fuel delivery pipe with sensor assembly (with fuel injector assembly) to the intake manifold.

      Note

      Be careful not to twist the O-ring.
