Don't understand how you can get a spark from the coil if the distributor isn't turning. That goes against how a coil works.

Blowing all those fuses and coil doing this something is grounded. A short to ground can be hard to find. You will have to check each circuit one at a time. A bare wire or some touching each other.

Looks like a defective capacitor.
