MBL,

Your symptoms are "classic" sheared roll pin, but that doesn't rule out other possibilities. It could also be a loose wire, a blown fuse, or, depending upon how you have run the wiring to your new ignition, it may even be a burned contact somewhere, like for instance at the ignition switch. Then of course, there's the electronics themsleves, the MSD 6A boxes are known to fail from time to time.

There is an easy way to rule out the sheared roll pin. Remove the distributor cap & crank the motor with the starter, if the distributor's rotor turns, the roll pin is OK. If the rotor doesn't move, the roll pin has sheared.
