Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle's negative battery terminal to prevent electrical shorts.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Remove Fuel Injectors

Tools Required: Socket set, fuel line disconnect tool, torque wrench.
Remove the engine cover (if applicable) by unscrewing the bolts.
Disconnect the electrical connectors from the fuel injectors.
Use the fuel line disconnect tool to remove the fuel lines from the injectors.
Unscrew and remove the mounting bolts holding the fuel rail in place.
Carefully lift the fuel rail with the injectors attached out of the engine.

3. Inspect and Clean

Inspect the fuel injectors for any signs of clogging or damage.
Use a fuel injector cleaning kit to clean the injectors if they are clogged.
If damaged, replace the fuel injectors with new ones.

4. Reassemble Components

Place the cleaned or new fuel injectors back into the fuel rail.
Reattach the fuel rail to the engine, securing it with the mounting bolts (torque to manufacturer specifications).
Reconnect the fuel lines and electrical connectors to the injectors.
Replace the engine cover if it was removed.

5. Final Checks

Reconnect the vehicle's negative battery terminal.
Turn the ignition on (without starting) to prime the fuel system and check for leaks around the injectors.
Start the engine and monitor for proper operation.
