1999 Honda Accord Car Wont Start

I was in an accident about a month ago. No other vehicles were involved, I hit the guard rail on the passenger side of the car. Other than the door being smashed in there was no visible damage. Before the accident the car ran perfectly like brand new. It sat in the impound for about a week until I could get it out. When I picked it up it had to be Jump started. I drove it home with no problems and it hasn't started since then. I figured I drained the battery because I left the hazards on. Took the battery to get charged they told me it was bad so I replaced the the battery and the battery post. My "smart" husband put the battery in wrong and blew a fuse replaced that fuse and tested all the others which was good. The cars still wont start the hazards work the horn sounds but that is it. No lights come on no sounds ( like the beeping when the key is in) no sound when you try to crank it nothing. What else could possibly be wrong?
