The coil will have continues 12V of power on the ignition switched terminal. the other terminal is connected to the distributor, that pulses. When checking for spark at the plugs geg a test plug , and ground it in a position where you can watch it when cranking the engine over. They sell a test plug with an attached alligator clip . You can clamp it to a ground and know it isn't going to flop into the fan or the like.
Did you ever remove the distributor cap and enshure that the distributor shaft and rotor are revolving?Also check to see if you have damaged the rotor .
