Cranked the injection pump up, engine ran away on startup...

If you got a bad turbo oil seal for the intercooler the engine will run away fed on motor oil.

Intercooler?

If I say anything else no one knows what I'm talking about. I call the air to air charge the aftercooler but some people call that the intercooler. OK The bearing oil seal on the inside of the turbo. Subject up for debate, seen them labeled both ways in manuals...

We're talking about a 6.5 diesel. There's no intercooler/aftercooler, just straight from the turbo into the intake. Nor would an intercooler ever have oil. The oil seal can fail in a turbo and introduce oil into the intake path leading to a runaway. But there's no oil at all in an intercooler.

Thank you for confirming from my first post. Sorry for the use of 2- syllible word. Dead topic for me.

Any update? I was amazed at the start up checks they do to rebuilt motors in the TM's. . . .

well then maybe it's the afterburner?? I know a leaky seal can keep the engine running but to take off and max out the RPM's just that quick? I'd have to check and see if it even had a seal!
I've gotten pretty stupid with 6.2s in the past and I've never.... lets just say they've held up VERY well, doubt you did any damage but keep us updated
