Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, fuel pressure gauge, safety glasses, gloves.
Safety Warnings: Disconnect the battery before working on electrical systems and relieve fuel system pressure before removal.

2. Remove Engine Cover

Remove any necessary components obstructing the engine cover.
Unscrew the bolts securing the engine cover using a socket set.
Carefully lift off the engine cover and set it aside.

3. Remove Fuel Rail and Injectors

Tools Required: Socket set, torque wrench.
Disconnect the fuel line from the fuel rail using a line disconnect tool.
Unplug the electrical connectors from each fuel injector.
Unscrew the bolts securing the fuel rail to the intake manifold.
Carefully lift the fuel rail, which will pull the injectors out of the manifold.

4. Inspect and Clean

Remove the old fuel injectors from the fuel rail.
Inspect the injector O-rings and replace them if damaged.
Clean the injector ports in the fuel rail and intake manifold using a carburetor cleaner to remove any carbon buildup.

5. Install New Injectors

Parts Required: Replacement fuel injectors, new O-rings.
Lubricate the new O-rings with clean engine oil to ensure a proper seal.
Insert the new injectors into the fuel rail and secure them in place.
Reattach the fuel rail to the intake manifold and torque the bolts to manufacturer's specifications.

6. Reconnect Fuel Line and Electrical Connectors

Reconnect the fuel line to the fuel rail.
Plug in the electrical connectors to each injector.
Replace any components that were removed to access the engine cover.

7. Reinstall Engine Cover

Place the engine cover back on and secure it with the bolts removed earlier.
