Solution

1. Preparation

Gather tools and parts (see list below).
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool if it has been running.

2. Remove the Fuel Injector

Tools Required: Socket set, ratchet, torque wrench, fuel line disconnect tool.
Remove the engine cover, if present, by unscrewing the retaining bolts.
Disconnect the electrical connector from the fuel injector.
Use the fuel line disconnect tool to relieve fuel pressure and disconnect the fuel line from the injector.
Remove the retaining clips or bolts securing the fuel injector to the intake manifold.
Carefully pull the fuel injector straight out of the rail, ensuring no debris enters the intake manifold.

3. Inspect and Replace

Inspect the old injector for signs of wear or damage. Check the O-ring for any cracks or deterioration.
If the injector is faulty, install a new fuel injector by reversing the removal steps:
- Lubricate the O-ring with engine oil.
- Insert the new fuel injector into the rail and secure it with retaining clips or bolts.
- Reconnect the fuel line and electrical connector.

4. Reassemble and Test

Reinstall the engine cover (if removed) and ensure all bolts are torqued to specifications (usually around 10-15 ft-lbs, check manufacturer specs).
Reconnect the negative battery terminal.
Start the engine and check for any leaks around the fuel injector area.
