Wont crank

I have a 2008 pontiac G6 that has a
brand new starter we put on because it
was doing this same thing. It will crank
with a wire ran from the hot wire from
the starter and touch hot post on
battety. I havent even had problems
since we put the starter on and today it
wont crank. Its been about two months
since we replaced the battery and
starter. Now its doing the same thing.
It will just make a click when u turn it
over.
