Use a volt meter and see if you have voltage to the + side of the coil with the key in the on position (hint: only leave the key in the on position JUST long enough to check for voltage, or it can damage points, coil, and/or a Pertronix Ignitor).

If you have ~7v or more, it's probably the coil or a problem with the distributor (points, sheered roll pin, bad magnetic pickup on an electronic module, etc.). If you don't have voltage at the + post, look for problems with the ignition switch and related wiring.
