Need help with similar sounding problem. 1985 300SD.
Started and ran normally until stopped running last week. Weather, 65 degrees, sunny. Drove 2 blocks. Accelerated from stop sign. Lost power, ran rough and engine stopped running in less than half a block. Tried restart several times. Coughed and ran rough a few seconds and died. Gas pedal down runs a bit longer but still rough and dies.
Changed primary and secondary fuel filters. Filled secondary filter with oil. Primed primary until full of fuel. Still no start. Coughs, revs rough a second or so and dies. Use only pump diesel always. New Bosch glow plugs last yr. Never touched in fuel tank filter. Next thing to try will be loosen nuts on top of fuel injectors 3/4 turn and see if fuel comes out.
I am not a pro. From your fix procedure, why does the IP need heating with torch. Is it propane torch or something else? How difficult is removing delivery valves and cleaning out? What is "Melt Down"? What is "Standyne"? Hope to get my old diesel running again. Hope I do not need a new injection pump.
Thanks again.

Problem solved. Heated the IP with a torch, Removed the injection pump delivery valves, sprayed stuff down, blew stuff out, checked the plungers were moving, topped off and primed everything with Melt Down. Cranked until it idled. Diesel/Stanadyne mix for the fill-up.
I just about gave up on the situation, we tried one more time and the IP started moving fuel to the injectors, we still are unclear definitively, it's running.
