Repair Procedures - Injector

Inspection

1. 1
   Turn the ignition off.
2. 2
   Disconnect the injector connector.
3. 3
   Measure the resistance between terminals 1 and 2 of the injector.
4. 4
   Make sure the resistance is within specification.

   Specification: Refer to "Specifications"

Removal

1. 1
   Turn the ignition OFF and disconnect the negative (-) battery cable.
2. 2
   Relieve the residual fuel pressure from the fuel line. (Refer to Fuel System - "Relieving Fuel Pressure in the Fuel Line")
3. 3
   Remove the delivery pipe and injector assembly. (Refer to Fuel System - "Delivery Pipe")
4. 4
   Disconnect the connector (A) and the retaining clip (B), then separate the injector from the delivery pipe.

   

Installation

1. 1
   Combustion Seal
2. 2
   Rubber Washer
3. 3
   Support Ring
4. 4
   O-ring

1. Installation is the reverse of removal.

Replacement

1. 1
   Remove the combustion seal (A) using cutting pliers.

   

2. 2
   Before installing the O-ring, clean the groove with a clean cloth. Any carbon deposits on the injector sealing surface must be carefully removed with a brass wire brush.

   

3. 3
   Place the O-ring installation guide (B) (SST No.: 09353-2B000) on the injector tip, taking care not to damage the injector tip (A). Press the O-ring (C) onto the tapered installation tool with your thumb and index finger until it enters the groove. The complete installation should not take more than 2-3 seconds.

   

   

4. 4
   To determine the O-ring size, first insert the injector into the sizing tool (A) (SST No.: 09353-2B000), then press and simultaneously rotate it 180° in the gauge tool.

   

5. 5
   Remove the injector from the gauge tool by rotating it in the direction opposite to that used during press-fitting.
6. 6
   Check the installation of the combustion seal (A).
