Valiant will not start. Help!

I have a 1964 Plymouth Valiant V200 Signet, I was out driving a few days ago and after leaving a stop light, the car stalled and then would not crank again.
The gauge states that there is 3/4 a tank of gas in it (though I wouldn't rule out the gauge is wrong) so I went to the station and got 2 gallons of gas to put in it.
Although the battery stated it had 13 volts, I attempted to jump the car off to see if that would work.
I have been having problems with the wiring coming disconnected from the ignition switch, so I looked and reconnected those.
The car still will not start.
Any ideas on where I could go from here?
