key on, engine off and you popped a coil?
I'd get my hands on a wiring diagram and start looking for grounded circuits. essentially you smoked a coil pack designed for thousands of volts without even placing a load on it. Without the motor running the alternator isn't spinning so you are simply working off battery voltage, that eliminates the regulator on that.
without the motor running you aren't firing the low voltage primary side off the coil, you wont generate voltage in the secondary side to the plug, so you have some crazy short someplace some allowing that much current to the coil pack to smoke it. without a wiring diagram you'll just be shooting in the dark. with a wiring diagram, even with basic knowledge, you can get pretty far by just taking one wire at a time, isolating it, testing it, and verifying continuity or shorts.
again, i'd be looking for a short someplace, and not even worry about the plugs and wires at this point. even if you did have a problem there, the fault occurred without the motor running- even if the motor were running, the pulse to fire a spark plug is so quick that even a completely grounded spark wire should at worst give you drivability issues and not pop the coil pack.
