Dirty connections on the firewall plug? Popular spot for corrosion
and plain dirt, makes for intermittent spark among other things when
unplugged and then reconnected again... you might pop it apart and
spray it bigtime with WD-40 or PB Blaster, maybe even give the
contacts a bit of a scrub with a stiff brush, and then see if your
no-start problem goes away.
If no help, dig out the volt meter and start chasing down the missing
voltage to the coil. Expect 12 volts with points open on both of
the terminals of the coil, switch ON. Points closed, the coil's +
terminal should have ~8 volts, give or take a volt or so, and of
course the - terminal should be zero.
