Fuel Injector: Service and Repair

REMOVAL
1. Relieve fuel pressure.
2. Disconnect couplers from each injector.
3. Remove delivery pipe from cylinder head.
4. Remove fuel injector.

CAUTION:
A small amount of fuel may be released when it is removed from delivery pipe.
Place a shop cloth under delivery pipe so that released fuel is absorbed in it.

INSTALLATION




1. Replace injector O-ring with new one using care not to damage it. Install grommet to injector.
2. Check if insulator is scored or damaged. If it is, replace with new one.
Install insulators and cushions to cylinder head.




3. Apply thin coat of fuel to O-rings and then install injectors into delivery pipe and cylinder head.
Make sure that injectors rotate smoothly. If not, probable cause is incorrect installation of O-ring. Replace O-ring with new one.
4. Tighten delivery pipe bolts and make sure that injectors rotate smoothly.
5. Connect couplers to injector securely and clamp injector wire.
6. With engine "OFF" and ignition switch "ON", check for fuel leaks around fuel line connection.
