2000 Buick Park Avenue Fuel Injector Parts and Q&A

• Q: How to service and repair the fuel injector on 2000 Buick Park Avenue?

  A: The first step for Fuel Injector repair requires users to use the fuel pressure gauge (J 34730) for releasing fuel pressure. The first step to service fuel injectors is to remove the Fuel Rail and subsequently the retaining clips and finally pull out the fuel injectors. During injection service the Fuel Injector upper and lower rings should be removed before refitting them with new rings. A nylon collar known as the o-ring back up properly positions the lower o-ring on the injector yet this back up needs to be reinstalled to avoid driveability issues and vacuum leak formation during Fuel Rail installation. The procedure for new injector installation includes oiling all fresh o-rings before inserting the o-ring back up followed by the lower o-ring and the upper o-ring . To complete this step install the Fuel Injector into the Fuel Rail after you have secured it with retaining clips followed by attaching the Fuel Rail while ending with the installation of the Fuel Injector sight shield. Order all necessary part numbers for fuel injectors and o-rings according to the exact application requirements of the vehicle service.
