Fuel Injector Replacement
Remove Electrical Connector Step 3 - Then, remove the mounting bolts located on each comer of the fuel rail, these locations can vary. This will enable the fuel rail to be loosened and allow the fuel injector to be removed.
Remove Fuel Rail Hold Down Bolts Step 4 - Once the bolts have been removed, proceed in gently lifting the fuel rail from the intake manifold, this will pop the rail loose allowing the fuel injector to be removed from the intake manifold. (Note: Occasionally it will be necessary to remove the fuel supply and return lines from the fuel rail, its best to leave these connected to avoid fuel contamination when possible.)
Lift Up On Fuel Rail Step 5 - After the fuel rail has been loosened, apply pressure downward to the fuel injector from the rail, this will pop the injector from the O ring seal located on either end of the injector. (Note: Some injectors are held in by a retainer clip that must be removed.)
