I have this problem and I found out that it is the jump start terminal, it's loose and wont let the charge go thru', if I open the hood and wiggle the jump start terminal I can get it to start.
it does when the weather gets above freezing, starts great, then when it is cold wont even turn over, acts like its dead.
