I have been down for a while tying up some loose ends on the car and I ran the battery dead, So I ran it to Advanced and tested and charged it. Showed to be good at over 725 CCA. When I put the battery back in, still nothing. Well not nothing, the boost controller led comes on, but then when I turn the key to accessory position the BC led goes off and the solenoid under the hood clicks. I try the lights, nothing. I try the radio, nothing. I replaced the positive and negative terminal connectors, and still nothing. I have literally checked every fuse on the car twice. The click sounds like its from the small black relays inside the underhood fusebox. I have no clue whats going on, but I am hung up pretty good. Please give me some suggestions. Thanks.

I was searching the forums and read something about a bad ground to the firewall. I ran a new 8 gauge wire from the negative terminal on the battery to the firewall right behind the battery. EVERYTHING WORKS FINE NOW.

That was easier than I was expecting. I spent 8 hours trying to figure it out. I am glad however that I spent the time, because I rewired some things a little better than what they were before.
 
Have you looked at your ECU yet? I had the same problem and it ended up being damaged tracks.
