Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working with electrical components.

2. Remove Fuel Injector

Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel injector harness connectors by pressing the release tab.
Remove any retaining clips or bolts securing the fuel rail.
Carefully lift the fuel rail with the injectors attached, ensuring not to damage the injector o-rings.
Remove the injectors from the fuel rail by gently twisting and pulling them out.

3. Inspect and Clean

Inspect the injector nozzle for blockages or deposits; clean with a specialized injector cleaner if necessary.
Replace any damaged o-rings on the fuel injectors.
Ensure the injector ports in the intake manifold are clean and free from debris.

4. Install New or Repaired Injectors

Insert the cleaned or new fuel injectors into the fuel rail, ensuring they seat properly.
Reattach the fuel rail to the engine and secure with bolts or retaining clips.
Reconnect the harness connectors to the injectors, ensuring a snug fit.

5. Reassemble and Test

Reinstall the fuel pump fuse and reconnect the negative battery terminal.
Turn the ignition to the "ON" position for a few seconds to prime the fuel system.
Start the engine and check for leaks around the injectors and fuel rail.
