Cap and rotor would need to be checked for cracks and a burn mark on the under side of the rotor, make sure the wires are good, check for spark from the coil wire, the coil could be bad, The coil, distributor ignition pick-up, and ignition control module are all components for developing a spark, these items can be tested at a Auto-Zone. Check for obvious reasons first like the cap, rotor, & coil for burn, carbon tracks first.

I would have the ignition control module & the coil tested. The coil has resistance values to measure in different sequences. The ICM makes and breaks the circuit to the coil for discharge. ICM took the place of the old points.
