Thanks, John
Yes, on all accounts. Pre-lubing is done exactly that way - use a drill and spin the pump. The distributor, however, gets turned by the camshaft and - in turn - spins the pump. Cranking the motor is more than fast enough to build pressure; you might have to crank it for a hair longer than you would normally do, but you will see pressure build.

If the dist drive gear pin is busted, you're not gonna build pressure because as soon as the pump starts pumping, the effort required to move that oil will far exceed the level of friction the busted pin will generate between the dist shaft and the gear.

You HAVE popped the dist out to have an overall look at it, right?
