PROCEDURE


  1. INSTALL FUEL INJECTOR ASSEMBLY

    Tech Tips

    Perform "Inspection After Repairs" after replacing the fuel injector assembly.



    1. A01V8U3C03
      *1 New O-Ring

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

    2. A01VAH6C01
      *1 O-Ring
      *2 Fuel Delivery Pipe
      *a CORRECT
      *b INCORRECT

      Apply a light coat of gasoline or spindle oil to the part of the fuel delivery pipe which comes into contact with the O-ring of the fuel injector assembly.

    3. Apply a light coat of gasoline or spindle oil to the O-ring again, and then install the fuel injector assemblies to the fuel delivery pipe.

      Note

      Make sure that the O-ring is not cracked or jammed when installing the injector assembly.

    4. Check that the fuel injector assembly rotates smoothly. If the fuel injector assembly does not rotate, replace the O-ring.

  2. INSTALL FUEL DELIVERY PIPE


    1. Install 4 new injector vibration insulators to the cylinder head.

    2. Install the 2 fuel delivery spacers to the cylinder head.

    3. A01V8N3C03
      *1 Fuel Delivery Pipe
      *2 Fuel Injector Assembly
      *3 Fuel Vibration Insulator
      *4 O-Ring

      Install the fuel delivery pipe together with the 4 fuel injector assemblies to the cylinder head, and then temporarily install the 2 bolts.

      Note

      Be careful not to drop the fuel injector assemblies when installing the fuel delivery pipe.

    4. Check that the fuel injector assembly rotates smoothly.

      If the fuel injector assembly does not rotate, replace the O-ring.

    5. Tighten the 2 bolts to the specified torque.

      Torque:
      21 N*m  { 214 kgf*cm, 15 ft.*lbf }

  3. CONNECT WIRE HARNESS


    1. A01V8PON01

      Attach the clamp to connect the wire harness.

    2. Install the 3 wire harness brackets with the 3 bolts.

      Torque:
      for bolt A
      9.0 N*m  { 92 kgf*cm, 80 in.*lbf }
      for bolt B
      10 N*m  { 102 kgf*cm, 7 ft.*lbf }

    3. Connect the 2 connectors.

    4. Connect the 4 fuel injector connectors.

  4. CONNECT FUEL TUBE SUB-ASSEMBLY


    1. Connect the fuel tube sub-assembly and install a new No. 2 fuel pipe clamp.

  5. CONNECT FUEL HOSE BRACKET


    1. A01V98JC01
      *1 Clamp

      Connect the fuel hose bracket with the bolt.

      Torque:
      13 N*m  { 133 kgf*cm, 10 ft.*lbf }

      Note

      If the fuel hose is detached from the clamp shown in the illustration, the clamp cannot be reused.

  6. INSTALL AIR CLEANER CAP SUB-ASSEMBLY

  9. INSPECT FOR FUEL LEAK


    1. Make sure that there are no fuel leaks after performing maintenance on the fuel system.


      1. Connect the GTS to the DLC3.

      2. Turn the ignition switch to ON, and then turn the GTS on.

        Note

        Do not start the engine.

      3. w/ Fuel Pump Control ECU

        Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed.


        Powertrain > Engine and ECT > Active Test
        Tester Display
        Control the Fuel Pump / Speed

      4. w/o Fuel Pump Control ECU

        Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed.


        Powertrain > Engine and ECT > Active Test
        Tester Display
        Control the Fuel Pump / Speed

      5. Check that there are no leaks from the fuel system.

        If there are fuel leaks, repair or replace parts as necessary.

      6. Turn the ignition switch off.

      7. Disconnect the GTS from the DLC3.
