Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Ensure the engine is cool before starting the work.

2. Remove Engine Cover

Use a socket set to remove any fasteners securing the engine cover.
Carefully lift off the cover and set it aside.

3. Access Fuel Injector

Locate the fuel rail and identify the stuck injector.
Remove any components obstructing access, such as intake ducts or hoses, using appropriate tools.

4. Disconnect Fuel Injector

Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the electrical connector from the injector.
Use a ratchet and socket to remove the fuel rail bolts and gently lift the rail to access the injector.

5. Remove Stuck Fuel Injector

If the injector is stuck, apply a penetrating oil around the base and let it sit for a few minutes.
Use a pair of pliers to gently twist and pull the injector out of the rail.
If necessary, replace the injector with a new one if it is damaged.

6. Install New Fuel Injector

Lubricate the O-ring of the new injector with clean engine oil to help with installation.
Insert the new injector into the fuel rail, ensuring it seats properly.
Reattach the fuel rail to the engine and tighten the bolts to the manufacturer’s torque specifications.

7. Reconnect Components

Reconnect the electrical connector to the injector.
Replace any components that were removed for access, ensuring all hoses and ducts are secure.

8. Final Checks

Reconnect the battery.
Replace the fuel pump fuse and prime the fuel system by turning the ignition to the ON position without starting the engine.
Check for leaks around the injector area.
