How do you change a fuel injector on a 2002 rav 4?

To change a fuel injector on a 2002 RAV4, first, disconnect the negative battery terminal and relieve the fuel pressure by removing the fuel pump fuse and starting the engine until it stalls. Next, remove the intake manifold or any components obstructing access to the fuel rail. Disconnect the fuel lines and electrical connectors from the injector, then remove the fuel rail with the injectors attached. Replace the old injector with a new one, reassemble the components in reverse order, and reconnect the battery.
