Now No Start

Update: Still not starting. I tried jumping the FP relay and the pump does
buzz like it used to, however doing that and cranking doesn't start it. I
also checked the distributor and it still spins and while it's a little
sloppy it doesn't appear the gear is broken. I'm in the process of changing
the fuel filter, and then I'll try maybe swapping in some different flywheel
