I talked with him..
Engine was running good when it came in.

Service = fuel filters replaced with new.

* Pre-filled filter with fresh dino diesel.
* 300 strokes on new style primer pump, heard bypass squeaking.
* Did try to bleed at injectors, no effect.
* Fuel tank is full of fresh diesel.
* Tried WD40, engine cranking seemed to slow.
* Using a HEAVY battery charger 150+ amp.

He is:
* installing lift pump repair kit MB# 000 090 02 10
* Checking fuel level in the large filter = possible fuel starvation
* Checking vacuum shutoff = remove hose and oil fill cap and crank
* Etc, etc, covered other data on the phone.
