Mep 831a black smoke won't rev up and shooting flames out the exhaust

Does the injection pump look like it was ever messed with, removed, or adjusted in anyway?

It’s hard to say. I do not think it has been messed with but it’s hard to tell.

I can tell ya from first hand experience if there is any air getting into the high pressure pump, even a little, it will spit and sputter and overall be a very unhappy little camper. I just went through that problem with the HDT that I'm working on. It sounded like the timing was WAY off and I think it was BUT it was caused by the fuel being injected very late due to the squishy air in the line.

I will definitely check this once my new injector arrives. Should be here on the 26th. Thanks!!!
