Solution

1. Preparation

Tools Required: Socket set, torque wrench, fuel line disconnect tool, OBD-II scanner, safety glasses, gloves.
Disconnect the vehicle battery to prevent electrical shorts.
Relieve fuel system pressure by removing the fuel pump relay and running the engine until it stalls.

2. Remove Engine Covers

Use a socket set to remove any engine covers obstructing access to the fuel injectors.
Keep track of all fasteners for reinstallation.

3. Disconnect Fuel Lines

Use the fuel line disconnect tool to safely detach the fuel lines from the injectors.
Have a rag handy to catch any residual fuel.

4. Remove Old Fuel Injectors

Unscrew the retaining clips or bolts holding the injectors in place using a socket set.
Carefully pull the injectors out of the fuel rail, ensuring not to damage the rail or surrounding components.

5. Install New Fuel Injectors

Lubricate the O-rings on the new injectors with clean engine oil to ensure a proper seal.
Insert the new injectors into the fuel rail and secure them with the retaining clips or bolts.
Reconnect the fuel lines, ensuring they are securely attached.

6. Reassemble Engine Components

Reinstall any engine covers removed in step 2, tightening fasteners to the manufacturer's specifications.
Reconnect the vehicle battery.

7. Test Fuel System

Reinstall the fuel pump relay and turn the ignition to the ON position (do not start) to prime the fuel system.
Check for leaks around the injector area and fuel lines.
