Spark From Coil vs. Spark from Distrubutor Cap

Is it normal to be getting rapid succesion spark from the coil plug wire, but only intermittent spark from the wires going from the distributor cap to the plugs? I have a crank but no start situation ... just about ready to give up. Have replaced coil, plug wires, new plugs, new fuel pump ... all fuses and relays check OK. Have not checked the ignitor module .. can I assume it's good if I'm getting spark? Any help appreciated .. car is 93 protege
