How to replace a fuel injector on Buick Rainier?

The first steps to replace a Fuel Injector are removing the Fuel Rail assembly while disconnecting the Fuel Injector harness connector from all fuel injectors. The procedure begins with carefully removing the retainer clip before extracting the Fuel Injector from the Fuel Rail assembly and discarding both the retainer clip as well as the injector o-ring seals (2, 4) from its ends. The correct Fuel Injector needs selection according to application since the Fuel Injector assembly bears a part number id and a four-digit code showing manufacturing month/day/year and shift. The new injector o-ring seals (2, 4) require oil lubrication before installation onto the injector followed by a new retainer clip placement. Insert the Fuel Injector through the rail injector socket from rear to front with the electrical connector protruding outside the socket while allowing the retaining clip to lock onto its flange.
