FIXED!!!!!

So I literally just had the same problem. I came out from church and my car would start. Everything seemed in order...it just wouldn't engage the starter. I tried everything until I went under the hood and began pulling fuses, it was the 20 amp 'horn stop' fuse was blown...I replaced it and immediately my alarm started going off...then blew the 20 amp I put in...replaced it with a 30amp and then disarmed with the key in the door...car started right up.

Likely the tranny is shot. My 2002 TLs tranny died @ 21k miles and the replacement died with only 60k miles. $3500 fix.
