      Note

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

    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 WITH FUEL INJECTOR

      *1 New O-Ring
      *2 Spacer

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

    2. Install the 4 spacers to the cylinder head sub-assembly.

    3. Install 4 new injector vibration insulators to the cylinder head sub-assembly.

    4. Install the 2 No. 1 delivery pipe spacers to the cylinder head sub-assembly.

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

      Note

      Do not drop the fuel injector assemblies when installing the fuel delivery pipe.

    6. Check that the fuel injector assemblies rotate smoothly.

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

    7. Tighten the 2 bolts.

      Torque:
      12 N*m  { 122 kgf*cm, 9 ft.*lbf }

    8. Connect the purge VSV with the bolt.

      Torque:
      9.0 N*m  { 92 kgf*cm, 80 in.*lbf }

    9. Connect the harness clamp bracket with the bolt.

      Torque:
      8.0 N*m  { 82 kgf*cm, 71 in.*lbf }

    10. Attach the wire harness clamp.

    11. Connect the purge VSV connector.

    12. Connect the 4 fuel injector assembly connectors.

  7. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL

    Note

    When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.

  8. 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 turn the GTS on.

        Note

        Do not start the engine.

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

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

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

      5. Turn the ignition switch off.

      6. Disconnect the GTS from the DLC3.
