sounds to me like you lost a head gasket. if your ignition control module took a dump, you would have either a total no-start condition, or you'd have a start/stall.
if the cap/rotor are bad, you'd end up with either a steady miss, or a no-start. if a wire is bad, you'd end up with a steady miss on the cylinder of the bad wire.
my problem, is that you're now saying you overheated the car several times. if that car came into my bay, and i knew it was overheated, the very first thing i'd be doing, is identifying the dead hole, pulling that plug, and checking the plug condition. while the plug's out, i'd check compression on that cylinder, and also do a leakdown on that cylinder with the radiator cap removed.
This. Because I would never try to diagnose other problems on a vehicle that possibly had this sort of damage.
The only thing you can do to diagnose your no start condition is to put a spark plug on the end of one plug wire, ground the shell of the plug, spin the engine over, and see if you get a spark. If you have a spark, look for a fuel pressure or volume problem. Other than that, you need tools and knowledge you do not have.
