Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool down completely before starting any work.

2. Remove Engine Cover

Using a socket set, remove the bolts securing the engine cover.
Gently lift off the engine cover and set it aside.

3. Access Fuel Injectors

Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the fuel rail using a line wrench.
Unplug the electrical connectors from the fuel injectors.

4. Remove Fuel Injectors

Remove the fuel rail bolts using a socket set.
Carefully lift the fuel rail with the injectors attached.
Gently pull out the leaking injector(s) from the fuel rail, taking care not to damage the rail.

5. Install New Injector(s)

Lubricate the O-rings on the new fuel injector(s) with clean engine oil.
Insert the new injector(s) into the fuel rail, ensuring they seat properly.
Reattach the fuel rail to the intake manifold and secure it with bolts, torquing them to the manufacturer’s specifications.

6. Reconnect Components

Reattach the fuel lines and electrical connectors to the injectors.
Replace the engine cover and secure it with the bolts removed earlier.
Reconnect the battery.

7. Test for Leaks

Reinstall the fuel pump fuse and start the engine.
Check for any fuel leaks around the injectors and fuel rail.
