No, it will spin ; Self prime and/or gravity prime

Muscular buzzing whine, not too loud but audible from driver's seat when
engine and radio off.

No, but...that's why they call it a coincidence.

I think you (or the gremlins) probably messed up the ground.  Remove ground
terminal and run wires direct from battery to both pump terminals.  If pump
behaves the same, sounds like bad pump. If pump runs, keep the wire from
battery to ground terminal, but use the regular power connection and try
again.  If pump runs, replace the ground wire from  pump to chassis.  If
not, there's a poor connection in the supply wiring (but I bet it's the
ground).   There are other ways to diagnose this, but that's the most
direct, and the pump and battery aren't very far apart.
