When you say "spark at the coil" do you mean the big high voltage lead that goes to the center of the distributor cap, or do you mean there is voltage at the two small terminals on either side of the center tower? If you're getting a high voltage spark from the center coil tower, you need to replace the rotor- - - -that's what sends the spark to individual plug wires. Rotors can short out sand send the spark to the distributor shaft instead of out to the plugs. If there's no spark from the center coil tower, recheck the wiring from the coil primary terminal to the points- - - -it's possible the plastic insulator block at the side of the distributor has shorted out.
