Solution

1. Preparation

Tools Required: Socket set, torque wrench, fuel line disconnect tool, screwdriver set, OBD-II scanner, multimeter, safety glasses, gloves.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery negative terminal to prevent electrical shock and accidental deployment of any components.

2. Relieve Fuel System Pressure

Locate the fuel pump fuse or relay in the fuse box and remove it.
Start the engine and let it run until it stalls, indicating that the fuel system is depressurized.
Turn off the ignition and ensure the engine is cool.

3. Remove Fuel Rail

Disconnect the electrical connectors from the fuel injectors.
Remove any retaining clips or screws securing the fuel rail to the engine.
Carefully disconnect the fuel line using a fuel line disconnect tool, ensuring to catch any residual fuel in a container.
Gently lift the fuel rail away from the engine, taking care not to damage the injectors.

4. Replace Fuel Injector

Remove the old fuel injector from the fuel rail by pulling it straight out; a slight twist may help.
Lubricate the O-ring of the new injector with clean engine oil to ensure a proper seal.
Insert the new fuel injector into the fuel rail until it clicks into place.

5. Reinstall Fuel Rail

Position the fuel rail with the new injectors back onto the engine.
Reconnect the fuel line and ensure it is secured properly.
Reattach any retaining clips or screws to secure the fuel rail.
Reconnect the electrical connectors to the fuel injectors.

6. Reconnect Battery and Check for Leaks

Reinstall the fuel pump fuse or relay.
Reconnect the battery negative terminal.
Turn the ignition to the "ON" position (do not start) to prime the fuel system, checking for leaks around the injectors and fuel rail.

7. Start Engine and Test

Start the engine and allow it to idle. Monitor for smooth operation and check for any error codes.
Perform a test drive to ensure the vehicle operates correctly under various conditions.
