What exactly shuts the engine off when you turn the key to off? And where is
it?

Well its the injector driver module aka IDM... Since the pcm powers down
with the ignition, so do the injectors. There by shutting down the engine
because it doesnt get any fuel in the cylinders.

Why might you be asking?? Are you experiencing a run-away engine? If you
are, I would be going after the o-rings on the injector not keeping the HP
oil out of the cylinders.. Thus allowing the engine to continue running..

I witnessed a run-away diesel once years ago. The rings were worn and it
was running off the oil or something. Scared the bejesus out of everyone in
the shop, including me.

Its funny how they have a way of doing that.. LOL I will say runaways are
more prominent on larger diesel engines that create larger amounts of
thrust, but none the less, its still scary as hell cause it wont shut down
unless you can kill its air supply.. I saw a Detroit D671 runaway one time
while I was in the Navy.. Its a two stroker, and the intake sucked so hard
that when we hit the air shutoff, it sucked the cover right into the
blower... LOL
