To change the fuel injectors on a 2002 Chevy Trailblazer, first disconnect the battery and relieve fuel system pressure. Then, remove the intake manifold to access the fuel rail. Detach the fuel rail from the injectors, remove the old injectors, and install the new ones with new O-rings. Reassemble everything in reverse order, ensuring all connections are secure before reconnecting the battery and starting the engine.
