How to service and repair the fuel injector on 2003 Chevrolet Trailblazer?

To maintain the fuel injector, one should take the fuel rail assembly out with a lot of care so as not to break the electrical connector pins. Un-harness the harness, un-clip the retainer and remove the injector, disposing of the clip and O-ring seals. Make sure that you order the correct injector, lubricate new O-rings, and put the injector into the fuel rail.
