Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool before starting the repair.

2. Remove the Fuel Injector

Tools Required: Socket set, fuel line removal tool, torque wrench.
Relieve the fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the injector using a fuel line removal tool.
Unplug the electrical connector from the fuel injector.
Remove the bolts securing the fuel rail (if applicable) and gently lift the fuel rail to access the injector.
Carefully pull the leaking fuel injector out of the engine.

3. Inspect and Replace

Inspect the old injector for damage or debris.
Clean the injector port in the engine with a lint-free cloth.
Apply a small amount of engine oil to the O-ring of the new injector to ensure a proper seal.
Insert the new fuel injector into the port and secure it in place.

4. Reassemble and Test

Reattach the fuel rail (if applicable) and torque the bolts to the manufacturer’s specifications.
Reconnect the electrical connector and fuel lines to the injector.
Reinstall the fuel pump fuse and reconnect the negative battery terminal.
Start the engine and check for leaks around the new injector.
