Just thought of one other thing...though it's remote.

You ARE attempting to start the engine with the engine stop lever in the up position--correct? If it's not all the way up as far as it could go, your fuel rack will not advance enough to allow the control sleeves to rotate and allow the plungers to compress fuel. It's conceivable that the engine stop mechanism has separated inside the governor, keeping the fuel rack in the "all stop" position. One way to check, would be to remove the side cover* on the IP and observe the fuel rack's movements when you move the engine stop lever and throttle arm.





*As a side note, curious diesel geeks with OM60x engines can remove the IP side cover and their ALDA units, then push down on the detent shaft (under the ALDA). Observing the relative position of the fuel rack whilst pushing on the shaft will provide a better understanding of how the ALDA functions. Pushing down limits fuel quantity (e.g. no boost is present), and releasing downward pressure advances the fuel rack (increased boost). You can push down on the detent shaft and move the throttle arm to full, then gradually release detent pressure and observe the fuel rack reach its full load position.
