dlheinz57 did pass the time by typing:
Blowing a 20A indicates a dead short. Since my books are good only up to 95, this is a stretch.
Fuse F2? medium blade type 20A? [ -20- ]
In the 93 that feed goes to the PCM directly and powers the coil (and a few other things) through the ASD relay.
Since it blew when you turned the ignition key on I'm suspecting a short after the relay. Could be the coil feed (dead short in the coil) or a bad ASD relay.
