1. Gather the necessary tools and parts. You'll need a set of wrenches, a screwdriver, a fuel injector removal kit, and new fuel injectors specifically for your vehicle.
2. Disconnect the battery. This is an important safety precaution to prevent electrical shock or sparks while you are working.
3. Remove the fuel line from the engine. There might be a release button or cap that you need to press to disconnect it.
4. Remove the fuel injector electrical connectors. There should be a small plastic clip that holds the connector in place. Gently pry it open and disconnect the connector.
5. Remove the fuel injectors. Use the injector removal kit to loosen the injectors and then pull them out of the engine.
6. Install the new fuel injectors. Make sure to align the new injectors properly and tighten them securely.
7. Reinstall the fuel line and electrical connectors.
8. Reconnect the battery.
9. Start the car and test the fuel injectors. Check for any leaks or unusual sounds.
Remember, working on fuel systems can be dangerous, especially if not done correctly. If you are not confident in your abilities, it's best to consult a professional mechanic for assistance.
