      While turning the fuel injector assembly left and right, install it to the fuel delivery pipe sub-assembly.

      Note


      • Do not damage the fuel injector assembly and O-ring.

      • Do not twist the O-ring.

      • After installing each fuel injector assembly, check that it turns smoothly. If not, replace the O-ring with a new one.

      Tech Tips

      Use the same procedure to install the other fuel injector assemblies.

  2. INSTALL FUEL DELIVERY PIPE SUB-ASSEMBLY

      *1 Fuel Delivery Spacer
      *2 Injector Vibration Insulator
      *a Fuel Delivery Pipe Sub-assembly Side
      *b Cylinder Head Side

      Install 4 new injector vibration insulators to the cylinder head.

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

      Tech Tips

      Install the fuel delivery spacer so that the longer protrusion is on the cylinder head side.

    3. Install the fuel delivery pipe sub-assembly with the 4 fuel injector assemblies with the 2 bolts.

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

      Note


      • Do not drop the fuel injector assemblies when installing the fuel delivery pipe sub-assembly.

      • Check that the fuel injector assemblies rotate smoothly after installing the fuel delivery pipe sub-assembly.

  3. CONNECT WIRE HARNESS


    1. A01EY6U

      Engage the clamp to connect the wire harness.

    2. Install the 2 wire harness brackets to the intake manifold with the 2 bolts.

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

    3. Connect the 4 fuel injector assembly connectors, throttle body with motor assembly connector and sensor wire connector.

  4. INSTALL VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)


    1. Install the vacuum hose clamp with the bolt.

      Torque:
      5.4 N*m  { 55 kgf*cm, 48 in.*lbf }

    2. Install the vacuum switching valve assembly with the bolt.

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

    3. Connect the 2 vacuum hoses and connector.

    4. Connect the union to connector tube hose and wire harness clamp.

  5. CONNECT FUEL TUBE SUB-ASSEMBLY

      *a Retainer
      *b O-ring
      *c Fuel Tube Connector
      *d Fuel Pipe
      *e Nylon Tube

      Connect the fuel tube sub-assembly to the fuel pipe.

      Note

      Check if there is any damage or foreign matter on the connecting parts of the fuel lines.


      1. Align the fuel tube connector with the fuel pipe, and push them together until the fuel tube connector makes a "click" sound. If it is difficult to push the fuel pipe into the fuel tube connector, apply a small amount of clean engine oil to the tip of the fuel pipe and reinsert it.

      2. After connecting the fuel lines, check that the fuel pipe and fuel tube connector are securely connected by pulling on them.

    2. Engage the claw and install the No. 1 fuel pipe clamp.

    3. Engage the clamp to connect the fuel tube sub-assembly to the fuel hose clamp.

  6. INSTALL AIR CLEANER CAP SUB-ASSEMBLY


    1. Install the air cleaner cap sub-assembly with the 2 clamps.

    2. Install the air cleaner hose with the hose clamp.

    3. Connect the ventilation hose to the cylinder head cover.

    4. Install the fuel vapor feed hose to the air cleaner hose.

    5. Connect the mass air flow meter connector and 2 wire harness clamps to the air cleaner cap sub-assembly.

    6. Connect the vacuum switching valve assembly to the air cleaner hose.

  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. Check fuel pump operation.


      1. Connect the intelligent tester to the DLC3.

      2. Turn the ignition switch to ON and turn the intelligent tester on.

        Note

        Do not start the engine.

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

      4. Check for pressure in the fuel inlet tube from the fuel line. Check that sounds of fuel flowing from the fuel tank can be heard. If no sounds can be heard, check the integration relay, fuel pump, ECM and wiring connectors.

    2. Inspect for fuel leaks.


      1. Check that there are no fuel leaks from the fuel system after doing any maintenance or repairs. If there is a fuel leak, repair or replace parts as necessary.

    3. Turn the ignition switch off.

    4. Disconnect the intelligent tester from the DLC3.

  9. INSTALL NO. 1 ENGINE COVER SUB-ASSEMBLY


    1. Fit the 3 retainers and install the No. 1 engine cover sub-assembly.
