Solution

1. Preparation

Tools Required: Socket set, torque wrench, fuel line removal tool, screwdriver, OBD-II scanner.
Disconnect the negative battery terminal to prevent electrical shorts.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.

2. Remove Engine Cover

Use the socket set to remove bolts securing the engine cover.
Gently lift off the cover and set it aside.

3. Access Fuel Injectors

Remove the intake manifold if necessary by disconnecting any hoses, sensors, or electrical connectors attached to it.
Unbolt and lift the manifold to access the fuel rail and injectors.

4. Remove Fuel Injector

Disconnect the fuel line from the fuel rail using a fuel line removal tool.
Unclip the electrical connector from the fuel injector.
Remove the bolts securing the fuel rail to the engine.
Carefully pull the fuel rail away from the engine, removing the fuel injector with it.
If necessary, use a flathead screwdriver to gently pry the injector out of the rail.

5. Install New Fuel Injector

Lubricate the O-ring of the new fuel injector with clean engine oil to ensure a proper seal.
Insert the new injector into the fuel rail or directly into the engine, depending on the design.
Reattach the fuel rail to the engine, securing it with bolts to the manufacturer’s torque specifications (typically around 15-20 Nm).
Reconnect the fuel line and ensure it is secure.

6. Reassemble Engine Components

Reattach the intake manifold, ensuring all hoses and connectors are properly connected.
Replace the engine cover and secure it with the bolts removed earlier.

7. Final Steps

Reconnect the fuel pump fuse and reconnect the negative battery terminal.
Start the engine and check for leaks around the injector and fuel rail.
