need help diagnosing a no-start, electrical problem Options

[6strngs]

So, the other day I went out to start my car, and it was cranking, but not starting. I turned it off, then tried again and nothing happened at all, no clicks, nothing. So I took my dad's car to work, but then when I got home, I tried again and noticed that when you turn the key just to the on position, nothing turns on like the clock, radio, any dash lights (CEL, SRS, etc) except the door ajar light. so I start checking fuses, notice that my 30A fuse for "AM2" is blown. I replace it with a spare, and get back in. turn the key just to the on, and everything is fine, the lights turn on and everything. then I go to crank and it turns over once and then nothing, it blew the fuse again. So basically my car is blowing the AM2 fuse everytime I turn the key to crank. I'm looking at the wiring diagrams but I'm not very good at diagnosing electrical problems. So any help appreciated on places to look for shorts.

Well at least somebody made an effort to help. lol. yeah, basically I seriously spent over 7 hours pouring over the wiring diagrams and testing thing before finally narrowing it down. I know for sure that it's coming from the black w/ orange stripe wire which runs from the fuse box, up to the ignition coil and igniter, and then on to the fuel injectors. where exactly in that stretch of wire harness the short is I'm unsure. I tried jiggling the harness in places with no luck. I think I'm just gonna go ahead and replace the whole harness with my spare one.
