1. INSTALL INJECTOR

1. Install a new insulator to the injector.

1. Apply a light coat of grease or gasoline to a new O-ring and install it to the injector.

1. Apply a light coat of grease or gasoline on the place where the delivery pipe touches the O-ring.

1. To install the fuel injector into the fuel delivery pipe, push the fuel injector while twisting it back and forth.

   NOTICE:
   1. Be careful not to twist the O-ring.
   2. After installing the fuel injector, check that it turns smoothly. If not, reinstall it with a new O-ring.

1. Position the injector connector so that it faces downward.

2. INSTALL FUEL DELIVERY PIPE

1. Install the 4 spacers to the cylinder head.

1. Connect the 4 injector connectors.

1. Install the 2 bolts and delivery pipe together with the 4 injectors.

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

1. Connect the 4 clamps and wire harness to the delivery pipe.

1. Connect the vacuum hose.

3. CONNECT FUEL HOSE

1. Connect the No. 1 fuel hose to the pulsation damper.

   1. Check that there is no damage or contamination in the connected part of the pipe.

   2. Align the axis of the connector with the axis of the pipe. Push the pipe into the connector until the connector makes a "click" sound. If the connection is tight, apply a small amount of fresh engine oil on the tip of the pipe.

   3. After having finished the connection, try to pull apart the pipe and the connector and confirm that they are securely connected.

   4. Attach the lock claws to the connector by pushing down on the cover, as shown in the illustration.

1. Connect the No. 2 fuel hose to the pressure regulator.

4. INSTALL THROTTLE BODY

1. Install a new gasket on the intake manifold.

   HINT:
     Align the protrusion of the gasket with the groove of the intake manifold.

1. Install the throttle body with the 2 bolts and 2 nuts.

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

1. Connect the water by-pass hose to the throttle body.

1. Connector the throttle control motor & throttle position sensor connector.

5. INSTALL INTAKE AIR CONNECTOR

1. Install the intake air connector with the 2 bolts, and tighten the 2 hose clamps.

   Torque:
     8.0 N*m{ 82 kgf*cm , 71 in.*lbf } for intake air connector
     5.0 N*m{ 51 kgf*cm , 44 in.*lbf } for hose clamp

6. CONNECT CABLE TO BATTERY NEGATIVE TERMINAL

7. PERFORM INITIALIZATION

1. Perform initialization (Click here).

   NOTICE:
     Certain systems need to be initialized after disconnecting and reconnecting the cable from the negative (-) battery terminal.

8. CHECK FOR FUEL LEAKS

1. Connect the intelligent tester to the DLC3.

   1. Turn the ignition switch ON.

      NOTICE:
        Do not start the engine.

   2. Push the intelligent tester main switch ON.

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

1. Check for fuel leaks.

   1. Check that there are no fuel leaks after performing maintenance anywhere on the fuel system.
