You say you checked drive shaft to make sure it was turning, did you pull 
the gear and look at the hex shaft on the bottom to make sure it isn't 
rounded?  Also- stop running the engine to troubleshoot.  That is simply 
compounding the damage.  Pull the distributor and drive gear out and use a 
pump primer and a speeder wrench.  Turn the pump by hand w/o running engine 
(counter-clockwise) with the 5/16 hex primer shaft and a speed handle with a 
5/16 socket.  If the driveshaft portion of the gear is rounde it won't drive 
the pump.  You would then expect to find you have oil pressure when cranking 
by hand and wit a valve cover off you may expect to even get oil up to a 
rockers.  If you have good resistance to turning the hand-rig but still 
don't read pressure you would have a good idea that system is plugged 
somewhere like a spun bearing.  If no pressure with hand rig you have either 
a leak downstream of pump or no pump prime.  I had a brand new re-built 
Pontiac engine do this to me after I did first oil change and it turned out 
to be the rubber check valve washer in the new oil filter I just put on was 
no good and the pump would not prime.  New oil filter fixed that.
