• Q: How to service and repair the fuel injector on 2002 Cadillac Seville?

  A: The first step for Fuel Injector servicing requires users to remove the Fuel Rail. You must first detach the Fuel Injector through a centering motion of its locking tab on the Fuel Rail before removing the upper and lower o-rings of the Fuel Injector. Discard these o-ring seals along with the injector. Correct placement of o-rings is crucial for leak prevention to avoid fuel-related fires and injuries; install the blue o-ring at the top and black o-ring at the bottom despite their identical size because they are composed of different materials. Proper servicing of fuel injectors requires replacement of all o-rings while using the correct o-ring to avoid vacuum leaks and driveability problems.lubricate the new upper and lower o-rings with clean engine oil, then install them on the Fuel Injector. Next follow the installation process with the Fuel Injector onto the rail then reinstall the rail.
