Fuel Injector: Service and Repair

1. Relieve fuel system pressure by starting engine with fuel pump relay (circuit open relay) disconnected and let run until engine dies, then slowly and carefully remove hose on outlet side of fuel filter. Cover with a clean rag while removing hose, to avoid spraying fuel in your face.

2. Disconnect intake duct from throttle body.

3. Remove intake manifold dynamic chamber and throttle body, as an assembly, from intake manifold.

4. Disconnect vacuum hoses and fuel hoses from fuel rail (fuel delivery pipe).

5. Disconnect electrical connectors from fuel injectors.

6. Remove fuel rail with injectors attached.

7. Remove injectors from fuel rail.

8. Install in the reverse order. Tighten bolts holding dynamic chamber to manifold to specified torque.
