In agreement with Tenders previous post, this is clear indication of an ignition circuit wiring problem. All the parts in place (points, condenser, rotor, distributor cap, coil) are functioning properly so replacing them will not address the no start/run problem.

fuel pump does not pull power from the coil positive terminal (where Moyer instructions say to connect)
Yes it does. It's just that you have no power to coil +.

Tested voltage across coil: zero. . . . . While it was running, tested voltage across ignition coil + to - : fluctuating 1 to 2 volts or so.
This test, between the two small coil posts, provides zero useful information and only tends to confuse the troubleshooting. The (-) post on the coil is not a ground. I'd much rather the convention was to identify it as a "D" terminal (for Distributor) but it's unfortunately not.

Chase down the ignition wire from the keyswitch to the coil, every inch of it by testing for voltage to a solid ground with the key on (coil disconnected for testing please). The first test is on the "I" terminal of the keyswitch.
