2388 CIH engine malfunction

Combine was sitting idling while I was hooking up a header cart.  It suddenly starting knocking and bucking. Went over and shut it off. No smoke or anything and no warning lights or readings. Waited a bit. Restarted it (easily) and immediately had the same bad results.

 

It seems like the fuel pump timing went to hell (?). Like severe pre-ignition.

 

Any ideas?

Have you checked fuel pump PSI? I agree with you that it sounds like fuel delivery vs an electrical issue. Evidentially your starter fuel pump is working if it restarted right up.

Did you git er figured out yet? Had an injection pump go bad on a 1440 once. Slipped a couple of teeth on the inside of the pump. It would run. However it galloped and smoked like crazy.

Don't they have a cummins engine? Seems odd it would strip teeth?

What year is your 2388? If 2005 or newer you could have had an injector fail causing a melted piston. If older than 2005 you might have stripped some teeth off the pump. Either way it doesn't sound good.
