Have you checked the turbo? Possible the shaft seized or broke.
Customer: replied 1 year ago.
No turbo running hot and black smoke new injectors
Expert:  dieseldan55 replied 1 year ago.
okay how about the air filter or blockage in intake. Tried running with filter out, no hoses collapsing?
Customer: replied 1 year ago.
Yes filter out
Expert:  dieseldan55 replied 1 year ago.
ok thanks. how about timing of the pump, and what about compression test. Black smoke is normally poor combustion and i wonder if these injectors are correct for motor or worn. How about oil level is it going down? compression test would be nice.

Ok
Expert:  dieseldan55 replied 1 year ago.
if the issue started with these injectors being put in i would recheck them for proper application. At the same time I believe this unit has glow plug holes you can access for the compression test. looking to see around 400-500 psi.
