I only checked the coil tower lead for continuity. I did check 2 different wires with the spark plug attached and grounded for spark. As someone suggested earlier I did pull the distributor and check that the roll pin was in place. I do have new set of wires I could swap out but just didn't see that as a possible problem since they had worked during initial and second fire up. Didn't think they would go bad while the engine was running.
