Fuel Injector Removal/Installation
CAUTION: Disconnecting/connecting the quick release connector without cleaning it may possibly cause damage to the fuel pipe and quick release connector. Always clean the quick release connector joint area before disconnecting/connecting, and make sure that it is free of foreign material.1. Complete the "BEFORE REPAIR PROCEDURE".
2. Disconnect the battery negative cable.
3. Remove the accelerator cable bracket. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.)
4. Disconnect the fuel injector connectors and remove the harness from the fuel distributor.
5. Remove in the order indicated below.
1. Plastic fuel hose
2. Vacuum hose
3. Fuel distributor
4. Fuel distributor insulator
5. Fuel injector insulator
6. Fuel injector
7. Grommet
8. Pulsation damper
6. Install in the reverse order of removal.
7. Complete the "AFTER REPAIR PROCEDURE".
Plastic Fuel Hose Removal Note
CAUTION: The quick release connector may be damaged when the tab is turned overly. Do not turn the tab over the stopper.
1. Disconnect the quick release connector from the pulsation damper as follows:
1. Push apart the lock clip and unlock it.
2. Lift the tab on the blue locking coupler until the fuel line can be released.
3. Pull the fuel hose straight back.
NOTE:
- The blue stopper may be removed from the quick connector. Take care not to loose it. Reinstall it to the quick release connector before reconnecting the fuel line.
- The orange locking coupler has two internal locking tabs which retrain the pulsation damper pipe. Be sure that the tab on the locking coupler is rotated until it stops to release two internal locking tabs.
2. Cover the disconnected quick release connector and pulsation damper with vinyl sheet or the like to prevent it from being scratched or contaminated with foreign materials.
Plastic Fuel Hose Installation Note
NOTE: A checker tab is integrated with the quick release connector for new plastic fuel hoses. The checker tab will be released from the quick release connector after it is completely engaged with the pulsation damper.
1. Inspect the plastic fuel hose and pulsation damper sealing surface for damage and deformation, and replace as necessary.
- If the quick release connector O-ring is damaged or has slipped, replace the plastic fuel hose.
2. Apply a small amount of clean engine oil to the sealing surface of the pulsation damper.
3. Push the quick release connector straight into the pulsation damper until a click is heard.
4. Lightly pull and push the quick release connector a few times by hand and verify that it can move 2.0 - 3.0 mm {0.08 - 0.11 in} and it is connected securely.
- If quick release connector does not move at all, verify that O-ring is not damaged and slipped, and reconnect the quick release connector
5. Attach the lock clip the quick release connector in the direction of the fuel distributor and lock it, as shown in the figure.
Fuel Injector Installation Note (FS only)
1. Install each fuel injector as indicated in the table.
2. Use new fuel injector O-ring.
3. Apply a small amount of engine oil to the O-ring and install them into the fuel distributor.
4. Verify that the O-ring and the fuel injector sealing surfaces are free of foreign material. Clean with gasoline if necessary.
5. Align the fuel injector notch with the fuel distributor and install the fuel injectors in the fuel distributor with light twisting motion so that the O-ring will not be folded.
