Ford Escape (2002 v6) no spark after alternator replaced

I replaced the alternator, drove it for 10-15 miles, turned it off, restarted it,
drove about 20 feet, and the car died. my alternator wires were crimped
between the alternator and the frame.  I removed them, taped them up, and
reconnected then, car cranked but wouldn't start. checked fuses, helo,
injector and ecm were blown.  replaced them, crank, but no start.  checked
plugs, no spark. fuel pump sounds like it's running, replaced coils, cam
position sensor, crank position sensor, wiring harness!, checked all grounds,
checked battery, checked o2 sensors, tps sensor, can't get a spark.  (anti-
theft is NOT activated, that's not the problem either.)  any ideas on what else
it could be?
