I tried starting my car back up and there wasn't a sound. It wouldn't turn over or do anything. I noticed all electronics were working so it wasn't the battery. I looked in the main fuse box under the hood and noticed the ign. fuse was blown, I replaced it with another 20amp and tried starting and it blew again.

Any ideas on what the problem might be, or how to fix that?

you've got a wire somewhere shorted to ground. I'd look around from where the fuse is at to where it goes into the firewall and make sure the coating around the wire is not exposing bare copper.
