2004 rancher es 4x4 no pull start or electric start

Hey folks!
I’m new to this so I’ll try to be clear in my question. I have a 2004 Honda rancher 350 es 4x4 that all of a sudden wont start. It started like this. It got below freezing and after a couple days I realized I had forgotten to disconnect the battery. I went outside to start it and of course the battery was dead. At this point I was able to pull start it. Put it in reverse to back out the shed went to put in nutral and it would not shift. I’m guessing because the battery was to weak. Turned it off still in reverse. Pushed it back in the shed. Come back later with a battery jumper, connected it, shift into neutral, and tried to start it. If I press the start button nothing happens. If I try to pull start it it won’t start. I put a new battery on it and still nothing. I checked the fuses and they are good. I’m completely confused as to what’s wrong with it at this point so hopefully you guys can help me out.
