Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shock.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.

2. Remove Fuel Rail

Tools Required: Socket set, torque wrench.
Remove the engine cover if necessary.
Disconnect the fuel lines from the fuel rail using a fuel line removal tool.
Unbolt the fuel rail using the socket set, and carefully pull the rail away from the engine.

3. Replace Fuel Injector

Tools Required: Injector puller tool (if available).
Remove the old fuel injector by pulling it straight out of the fuel rail.
Lubricate the O-ring of the new injector with clean engine oil.
Insert the new fuel injector into the fuel rail, ensuring it seats properly.

4. Reinstall Fuel Rail

Carefully position the fuel rail back onto the engine.
Bolt the fuel rail back in place and torque the bolts to manufacturer specifications.
Reconnect the fuel lines and ensure they are securely fastened.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Replace the fuel pump fuse and turn the ignition to the "On" position without starting to prime the fuel system.
Check for leaks around the injector area.
Start the engine and monitor for smooth operation.
