Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Socket set
- Torque wrench
- Fuel pressure gauge
- Screwdrivers (flat and Phillips)
- Injector puller (if necessary)
- Clean rags
- Safety goggles and gloves
Safety Warnings:
- Disconnect the battery before starting work.
- Allow the engine to cool before beginning the procedure.
- Relieve fuel system pressure before servicing.

2. Relieve Fuel System Pressure

Locate the fuel pump relay in the fuse box.
Remove the relay and start the engine; it will stall once the fuel pressure is relieved.
Turn off the ignition and disconnect the battery.

3. Remove Engine Cover

Use the appropriate socket to remove bolts securing the engine cover.
Gently lift and remove the engine cover to access the fuel rail and injectors.

4. Disconnect Fuel Lines

Use a fuel line quick disconnect tool to carefully disconnect the fuel lines from the fuel rail.
Place a clean rag underneath to catch any residual fuel.

5. Remove Fuel Rail

Unscrew the bolts securing the fuel rail using the socket set.
Gently pull the fuel rail away from the intake manifold, ensuring the injectors separate from the manifold.

6. Replace Fuel Injectors

Carefully pull the old fuel injectors out of the fuel rail.
Lubricate the O-rings of the new fuel injectors with clean engine oil.
Insert the new fuel injectors into the fuel rail until they snap into place.

7. Reinstall Fuel Rail

Align the fuel rail and carefully push it back onto the intake manifold, ensuring the injectors seat properly.
Secure the fuel rail with the previously removed bolts, tightening to the manufacturer's specified torque.

8. Reconnect Fuel Lines and Battery

Reattach the fuel lines to the fuel rail, ensuring a secure connection.
Reconnect the battery and install the engine cover.

9. Check for Leaks

Turn the ignition to the "On" position without starting the engine to pressurize the fuel system.
Inspect the fuel rail and injectors for any signs of leaks.
