How to service and repair the fuel injector on GMC Envoy?

Start by disconnecting the Fuel Rail assembly but ensure no damage happens to the pin or the nozzle of the Fuel Injector then refrain from placing the electrical component in any cleaner because doing so could harm it. The Fuel Injector leak can cause engine oil to mix with fuel during the service and repair procedures. Separate the Fuel Injector harness connector before removing the retainer clip and extracting the Fuel Injector out from the Fuel Rail while discarding both the retainer clip and injector o-ring seals (2, 4) from both sides of the injector. Check the application when getting new fuel injectors because the Fuel Injector assembly displays a part number identification together with a four-digit build date code which shows the manufacturing month, day, year, and shift. The installation begins with cleaned engine oil on new injector o-ring seals (2, 4) before placing them on the injector followed by new retainer clip installation on the injector. Complete the install by inserting the Fuel Injector into the Fuel Rail injector socket with the retaining clip locked onto a flange on the socket while maintaining the electrical connector facing outward.
