FUEL INJECTOR REMOVAL
PROCEDURE
DISCHARGE FUEL SYSTEM PRESSURE
CAUTION:Do not disconnect any part of the fuel system until you have discharged the fuel system pressure.
After discharging the fuel pressure, place a cloth or equivalent over fittings as you separate them to reduce the risk of fuel spray on yourself or in the engine compartment.
