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.
