New Timing chain, now wont start

[HughO]

I have a toughie, folks. My project car is a 1981 240 D in which previous owner replaced the timing chain and then it wouldn't start. Only 100K miles. He said probably bad glow plugs. NOT! So far I have checked cam timing, adjusted valves(WAY OUT!) , bled the system(lots of air bubbles top of filter, and cracked the injector lines. NO fuel coming to injector lines! He also had removed the vacuum pump(WHY?) which I replaced. The vacuum pump is driven by the timing chain and I assume is keyed to the injection pump. I can see the vacuum pump turning when I manually rotate the engine. Is it possible the injection pump is not turning ? IE., could he have disconnected it somehow? Is there any way to tell if the injection pump is rotating short of removing it entirely? Note I have done the timing chain R&R twice on 123 cars and everything went smoothly so I don't see how he screwed this job up. IDEAS!??
