It's something you won't have to worry about with a modern diesel engine not saying it can't happen but it would almost be impossible in a modern diesel truck. A runaway diesel is basically engine has no monitoring of the fuel intake basically the more fuel you get the engine the faster it will run. On the farmer runaway diesel can also happen if the tractor flips over and burns its own oil that floods the engine when it flips. Some of the old Dodge trucks the kids turn idle adjustment too high and the engine starts to accelerate you need to quickly do something with the air intake to starve the oxygen. Don't ask me how I know growing up on a farm we blowing up a few engines that way LOL
It's usually the engine running on motor oil instead of diesel that is being drawn in through the crankcase breather. Everything you want to know but watching the videos on YouTube is more fun for sure... LOL
Also, if a diesel starts sucking in gas like raw propane or natural gas (like a release of gas in a refinery or on a well site) through the intake they will run away.
My son's 05 DMax came from the oil fields in Alberta. It had an air shutoff on it to prevent runaway issues. Required for trucks that are near drilling sites as far as I know. If the air has combustible fumes the engine will run on that as well as the fuel it has which causes a race condition.

Yep......we ran them too, in certain applications.
Just had a 02 Duramax in the shop for a turbo. When it grenaded it pumped around half a gallon of oil into the intercooler. If I wouldn't have removed it and drained the oil out I likely would have had a runaway when restarting with new turbo.

A local diesel shop near where I used to live had this happen with a 6.0. Went on a test drive and it went wide open burning the tires off. Threw is in park until it blew up.
