Fuel Injector: Service and Repair
Removal Procedure
CAUTION: The fuel system is under pressure To avoid fuel spillage and the risk of personal injury or fire, it is necessary to relieve the fuel system
pressure before disconnecting the fuel lines.
1. Relieve the fuel system pressure. Refer to "Fuel Pump".
2. Disconnect the negative battery cable.
3. Disconnect the fuel injector harness connectors.
4. Remove the fuel line at the fuel pressure regulator. Refer to "Fuel Pressure Regulator (DOHC)".
5. Remove the fuel inlet line.
6. Remove the fuel rail mounting bolts.
NOTE: Before removal, the fuel rail assembly may be cleaned with a spray-type cleaner, following package instructions. Do not immerse the fuel
rails in liquid cleaning solvent. Use care in removing the fuel rail assembly to prevent damage to the electrical connectors and the injector spray
tips. Prevent dirt and other contaminants from entering open lines and passages. Fittings should be capped and holes plugged during service.
IMPORTANT: If an injector becomes separated from the rail and remains in the cylinder head, replace the injector O-ring seals and the retaining
clip.
7. Remove the fuel rail with the fuel injectors attached.
