CAUTION / NOTICE / HINT

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during direct fuel injector assembly removal/installation are shown below.

CAUTION:

• Never perform work on fuel system components near any possible ignition sources.
• Vaporized fuel could ignite, resulting in a serious accident.

• Do not perform work on fuel system components without first disconnecting the cable from the negative (-) auxiliary battery terminal.
• Sparks could cause vaporized fuel to ignite, resulting in a serious accident.
• To prevent serious injury due to fuel spray from the high-pressure fuel lines, always discharge fuel system pressure before removing any fuel system components.

NOTICE:

• After the ignition switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 120 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal.
• This procedure includes the removal of small-head bolts. Refer to Small-Head Bolts of Basic Repair Hint to identify the small-head bolts.

2. DISCONNECT WIRE HARNESS

3. REMOVE FUEL DELIVERY PIPE

NOTICE: When replacing the fuel delivery pipe, it is necessary to replace the No. 1 fuel pipe sub-assembly with a new one. Make sure not to touch or strike the tips of the direct fuel injector assemblies. Pull and remove the fuel delivery pipe in a straight line without tilting it.

4. REMOVE DIRECT FUEL INJECTOR ASSEMBLY

(1) Secure the fuel delivery pipe in a vise between aluminum plates and pull out the 3 direct fuel injector assemblies.

NOTICE:

• Pull and remove each direct fuel injector assembly in a straight line to avoid damaging the seal surface of the fuel delivery pipe O-ring.
• After removing the direct fuel injector assemblies, remove any O-rings, No. 1 fuel injector back-up rings and No. 3 fuel injector back-up rings remaining on the fuel delivery pipe side.
• Attach a tag or label with the corresponding cylinder number to each direct fuel injector assembly so that they can be installed to their original locations.
• Cover the tip of each direct fuel injector assembly to prevent it from being damaged.

5. REMOVE NOZZLE HOLDER CLAMP

6. REMOVE NO. 3 FUEL INJECTOR BACK-UP RING

NOTICE: Do not damage the area that contacts the O-ring.

7. REMOVE NO. 1 FUEL INJECTOR BACK-UP RING

8. REMOVE C-RING

9. REMOVE INJECTOR VIBRATION INSULATOR

10. REMOVE FUEL INJECTOR SEAL

(1) Using the tip of needle nose pliers, pinch and pull the fuel injector seal at several points to stretch it.

NOTICE:

• Excessively pinching the fuel injector seal may damage the groove of the fuel injector assembly.
• If a fuel injector assembly is dropped or the tip of the fuel injector assembly is struck, replace it with a new one.

(2) Remove the fuel injector seal from each fuel injector assembly.
