Solution

1. Preparation

Tools Required:
- Socket set
- Screwdrivers
- Torque wrench
- Fuel pressure gauge
- Multimeter
Disconnect the negative terminal of the battery to prevent any electrical shorts.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.

2. Remove Fuel Injector

Locate the fuel rail and remove any necessary covers or components obstructing access to the fuel injectors.
Use a socket set to remove the bolts securing the fuel rail.
Carefully pull the fuel rail away from the intake manifold, taking care not to damage the fuel lines.
Disconnect the electrical connector from the stuck fuel injector.
Use a fuel injector puller or gently twist and pull the injector to remove it from the fuel rail.

3. Inspect and Clean

Inspect the fuel injector for signs of carbon buildup or damage. If clogged, soak the injector in a fuel injector cleaner solution for several hours.
Use compressed air to blow out any debris or cleaner from the injector.
Check the O-rings on the injector; replace if damaged.

4. Install New or Cleaned Injector

Apply a small amount of engine oil to the O-rings of the fuel injector to ensure proper seating.
Reinsert the fuel injector into the fuel rail, ensuring it is seated correctly.
Reattach the fuel rail to the intake manifold and torque the bolts to the manufacturer’s specifications.
Reconnect the electrical connectors.

5. Reassemble and Test

Reinstall any components previously removed to access the fuel injectors.
Reconnect the fuel pump fuse and the negative terminal of the battery.
Start the engine and check for leaks around the fuel rail and injectors.
