No Start or Crank
 

I replaced the starter and carnkshaft position sensor but I still can't get the car to crank. My battery appears to be fine unless it does't have enough juice. I tried the short cut from the fuse box to the starter with no success. I am in Texas, the car did overheat and the A/C quit all at the same time, I'm at a loss as what to do, What function does the fuse have on top of my battery? I tend to have problems with that. Botom line my car has been sitting in my driveway for over a year and I"m about to give up on it. Please help.... There are many threads on this topic but I can't find a solution
