Injectors

Warning

Work with removing of fuel rails, including injectors, involves interfering with the cars fuel system. Therefore the following points should be observed in connection with repairs:

• Work only in a well-ventilated area! If approved equipment for the extraction of fuel vapours is available, be sure to use it.

• Wear suitable gloves! Prolonged contact with fuel can cause skin irritation or dermatitis.

• Keep a class BE fire extinguisher close at hand! Beware of sparks caused by short circuits and when connecting and disconnecting leads in electrical circuits.

• Smoking prohibited!


To remove


Important

Observe utmost cleanliness when working with injectors. Clean around the injectors, fuel rail and intake manifold and blow clean with compressed air.


Important

To reduce the risk of remaining fuel pressure, remove the fuel pump fuse no. 32 when the car is idling. Turn off the ignition when the engine has stopped. Refit the fuse.



1. Remove the resonator above the throttle body.

2. Remove the hose to the crankcase ventilation and the IAC- valve with hoses.


3. Remove the bracket for the dipstick and accelerator/cruise-control cables.

4. Remove the 4 retaining screws, 2 in each end of the fuel rail, and the 2 screws for the cable channel.


5. Carefully lift up the fuel rail.

6. Remove the two protectors and loosen the valve connector.

7. Remove the lock braces that attach the injectors to the fuel rail and pull out the injectors.


To fit



1. Fit the injectors to the fuel rail and secure them with the retaining clips

2. Fit the injectors' electrical connectors. check that the connectors are correctly fitted.

3. Carefully press the fuel rail in place.

4. Fit the 4 retaining screws, 2 in each end of the fuel rail, and the 2 screws for the cable channel.

5. Fit the bracket and the dipstick and accelerator/cruise-control cables.


6. Fit the IAC valve with hoses and the hose for the crank house ventilation.

7. Fit the resonator above the throttle body.


Important

During assembly the O-rings between the resonating chamber and throttle body may be incorrectly positioned with the result that the engine takes in air that has not passed through the mass air flow sensor. This could impair driveability with consequent fault diagnosis measures.

When any work is done that involves removing the resonating chamber from the throttle body, the following steps must always be taken:

• Check the condition of the O-rings and that they are properly seated. Replace any that are deformed.

• Grease the O-rings with non-acidic petroleum jelly (vaseline).
