Solution

1. Preparation

Tools Required: Socket set, torque wrench, O-ring pick, fuel line disconnect tool, cleaning cloths.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery (negative terminal).

2. Relieve Fuel System Pressure

Locate the fuel pump fuse in the fuse box and remove it.
Start the engine and let it run until it stalls to relieve the fuel pressure.
Turn off the ignition.

3. Remove Fuel Rail

Disconnect the electrical connectors from the fuel injectors.
Use a fuel line disconnect tool to carefully detach the fuel lines from the rail.
Remove the bolts securing the fuel rail to the intake manifold and lift the rail with the injectors off the engine.

4. Replace Fuel Injector

Carefully remove the faulty fuel injector from the rail using an O-ring pick.
Inspect and clean the injector seat on the fuel rail.
Install a new O-ring on the new injector and lubricate it lightly with engine oil.
Insert the new injector into the fuel rail until it clicks into place.

5. Reassemble Components

Reattach the fuel rail to the intake manifold and secure it with the bolts to the manufacturer's torque specifications (typically around 15-20 Nm but refer to service manual).
Reconnect the fuel lines and ensure they are secure.
Reconnect the electrical connectors to the injectors.

6. Restore Fuel System Pressure

Reinstall the fuel pump fuse.
Reconnect the battery (positive terminal first, then negative).
Turn the ignition to the "ON" position without starting to prime the fuel system, then check for leaks.
