Update: I pulled the main fuel pump assembly, ran the pump in a bucket of diesel fuel, both forwards and backwards, and got no crud out of it. The fuel filter, however, seemed to be clogged as there was a lot of black debris coming out of it when I drained it.
I got a new filter from Phil (Partsshop) and installed it. The car started right up, stalled a few times, but ran for a while if I kept it about 3000 rpm. (yes, the tachometer works), but finally stalled and now it won't start again, so I'm back to the original condition. I pulled the fuel line from the tank and the fuel flows nicely and it is clean.

I'm about ready to simply install two new fuel pumps, unless someone has a bright idea about something else that could be causing this condition. Thanks for all your help!
