1. Relieve fuel system pressure. This can be done by disconnecting the fuel pump relay, starting the engine, and allowing it to run until it stalls.
2. Disconnect fuel lines. Disconnect the fuel lines from the fuel injectors and fuel filter.
3. Remove fuel injector hold-down bolts. Use a wrench to loosen and remove the bolts securing the fuel injectors in place.
4. Remove fuel injectors. Use a pry tool to gently lift the fuel injectors out of the fuel rail.
5. Install new fuel injectors. Insert the new fuel injectors into the fuel rail. Secure the injectors with the hold-down bolts.
6. Reconnect fuel lines. Reconnect the fuel lines to the fuel injectors and fuel filter.
7. Pressurize fuel system. Start the engine and allow it to run for a few minutes to pressurize the fuel system.
8. Check for leaks. Visually inspect the fuel lines and connections for any leaks. Repair any leaks as necessary.
It's important to note that the fuel injection system is under high pressure, so take necessary precautions and safety measures when working on it.
