When you turn the key to start it, nothing happens?? Do you hear any noise at all?? I had something similar happen to me a couple weeks ago in my 2001 TJ. I had all power. Lights, radio, horn, etc. When I turned the key to start, I could hear a relay click, but that was all.
Check out this thread I started, when I was having issues. Should help you narrow it down a bit.
