Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, multimeter, fuel pressure gauge, screwdrivers, fuel injector removal tool.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery cable to prevent electrical shorts.

2. Remove Engine Cover

Unscrew any bolts or fasteners securing the engine cover.
Gently lift the cover off and set it aside.

3. Access Fuel Injectors

Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the fuel rail (use a rag to catch any spillage).
Disconnect the electrical connectors from each fuel injector.

4. Remove Fuel Rail and Injectors

Remove the bolts securing the fuel rail to the intake manifold.
Carefully lift the fuel rail off, ensuring the injectors come out with it.
If necessary, use a fuel injector removal tool to extract the injectors from the rail.

5. Install New Fuel Injectors

Lubricate the O-rings of the new injectors with clean engine oil to ensure a proper seal.
Insert the new injectors into the fuel rail and press them in until they seat properly.
Reattach the fuel rail to the intake manifold, tightening bolts to manufacturer torque specifications.

6. Reconnect Fuel Lines and Electrical Connectors

Reconnect the fuel lines to the fuel rail.
Reconnect the electrical connectors to the injectors, ensuring a secure fit.

7. Reinstall Engine Cover

Place the engine cover back on and secure it with bolts or fasteners.

8. Reconnect Battery and Test

Reconnect the negative battery cable.
Start the engine and check for leaks around the injectors and fuel lines.
