How to replace a fuel injector on GMC Sierra 3500?

You need to begin by removing the Fuel Rail yet maintain all Fuel Injector electrical connector pins along with nozzles and keep the Fuel Injector dry from any cleaning solutions which could harm its electrical element. Watch for oil contamination by fuel because the fuel injectors have a leaking issue. The first step consists of removing both halves of the Fuel Injector retaining clip followed by extraction of the injector from the Fuel Rail while discarding the injector o-ring seals (2, 4) at the ends. Prior to replacement use the build date code stamped on the injector to order correct parts because the date code shows both the month of manufacturing and the factory production shift and day along with year. Place a new retaining clip onto the Fuel Injector after applying clean engine oil to the new o-ring seals (2, 4) and installing them to their positions. Push the Fuel Injector into the Fuel Rail with the electrical connector facing outwards so the retaining clip can lock onto a flange of the rail injector socket before reinstalling the Fuel Rail.
