Hi my name is***** will be glad to help. The coil has a power and ground. Test for power with the key on to the coil and then the ground side gets ground signal from the distributor as it turns so connecting and disconnecting the ground to a good ground with power on the + side should fire the coil. Check with a spark tester or grounding the plug wire to view the spark. Or do the same with the engine cranking. If the coil tests good you could have a fault distributor if you have confirmed power to the coil, the coil is good bit wont fire.
