Jeep won't start and blowing ASD fuse

I went to start my jeep today and it clicked once then nothing. I thought maybe a dead battery even though its fairly new, so I tried jump starting with no luck. Checked fuses and realized the ASD fuse had blown. So I replaced it and it popped again when I tried starting it. The gas gauge and battery gauge are also not working. I tried checking around the o2 sensors and fuel injectors for worn or melted wires but saw nothing obvious. I will dive into the wiring deeper tomorrow. Any other suggestions on what I can look for or try? It is a 2006 4.0 automatic, no recent modifications or anything. Thanks for any help you can give.

Awesome thanks guys. I should be able to dive into it more tomorrow afternoon and I will update ya'll with anything I find out. Thanks again for the help.

Well I got time this morning to work on the jeep and I threw a new fuse in and it started right up. I tried moving around the wires that I inspected the other day, hoping it would short out again but had no luck. I left the battery disconnected for a few days, is there anything that could have gotten reset that was causing the ASD fuse to blow? I am worried to drive very far because I assume there is still a short somewhere, just not sure where?
