Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.

2. Remove Fuel Injectors

Tools Required: Socket set, torque wrench, fuel injector puller (if necessary), safety goggles, gloves.
Remove the intake manifold if required to access the fuel rail and injectors.
Disconnect the fuel lines from the fuel rail and plug them to prevent fuel spillage.
Remove bolts securing the fuel rail and gently pull it away from the engine.
Carefully lift out the fuel injectors from the fuel rail.

3. Inspect and Clean

Inspect each injector for clogs or damage; if clogged, soak in a cleaning solution designed for fuel injectors.
Use a soft brush to clean the injector nozzles, ensuring not to damage them.
If any injectors are damaged, replace them with new ones.

4. Reinstall Fuel Injectors

Apply a small amount of engine oil to the O-rings of the new or cleaned injectors for proper sealing.
Insert the injectors back into the fuel rail and ensure they are seated correctly.
Reattach the fuel rail to the engine, securing it with bolts to the manufacturer's torque specifications.
Reconnect the fuel lines and ensure there are no leaks.

5. Final Assembly

Reinstall the intake manifold if it was removed.
Reconnect the battery and fuel pump fuse.
Start the engine and check for fuel leaks around the injectors and fuel rail.
