Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the battery to prevent electrical short circuits.

2. Remove Engine Cover

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

3. Access Fuel Injectors

Locate the fuel rail where the injectors are mounted.
Detach the fuel lines by releasing the retaining clips. Use a rag to catch any fuel that may spill.
Unbolt the fuel rail from the intake manifold using a socket set.

4. Remove Fuel Injectors

Disconnect the electrical connectors from each fuel injector.
Gently pull the injectors out of the fuel rail. If they are stuck, use a twisting motion to break them loose.

5. Install New Fuel Injectors

Lubricate the O-rings of the new fuel injectors with clean engine oil to ensure a proper seal.
Insert the new injectors into the fuel rail until they click into place.
Reattach the fuel rail to the intake manifold and secure it with bolts.

6. Reconnect Fuel Lines and Electrical Connectors

Reconnect the fuel lines and ensure all retaining clips are securely fastened.
Reattach the electrical connectors to each injector.

7. Reinstall Engine Cover

Place the engine cover back and secure it with bolts.
Reconnect the battery.

8. Test the System

Turn the ignition key to the "ON" position without starting the engine to pressurize the fuel system.
Check for leaks around the injectors and fuel lines.
