Hi Big bang, Is your vehicle a diesel? If it's petrol injection the fuel cut off is not a separate switch. When you turn off the engine you also turn off the power to the injectors and therefore cut the fuel feed. If the engine is dieseling after turning off, I believe you have a problem with a leaking injector. This will also become evident when starting as the engine will take longer to fire, as it will have lost fuel rail pressure. Regards John
There is what is called a fuel rail. The fuel injector fits in between the fuel rail and the intake of the engine. If you look around the rail you will find a few bolts (usually 10mm) holding the rail in place. remove the rail bolts and gently pry up the rail. The injectors fit into each one with an o-ring sealing each side. Watch because sometimes the o-ring will stay in the rail or intake and you want to remove them before trying to put the new injector into it. If you have a little petroleum jelly, put a small amount on the o-ring before inserting it in the rail and intake. Line up all the injectors with the rail and intake and gently push them in. When all are lined up you can lightly tap the rail with a hammer, LIGHTLY tap it into place and reinstall the retaining bolts.
