Spark INTO the coil. Well there is your problem! it shouldn't be sparking into the coil but only out of the distributor
Try hot wiring it. ID the positive secondary lead to the pickup in the distributor and run a wire straight from the battery. If that doesn't work your coil or the pickup is bad. If it does work suspect the ignition switch.
In the old days of points it was a pretty simple thing to diagnose since you could see all the players and if they were working. Now you have to take it on faith that the inductor tooth is activating the pickup and that the voltage is being interupted when it's supposed to.
