First,and this will sound silly,make sure the cables weren't reversed,and spinning the starter backwards(it's happened to the best of us).Second,make sure the battery is fully charged.Even new batteries can lose their charge setting in the store.
Third,check all the ends of the cables to make sure they are clean/tight.
Fourth,and perhaps most important,make sure that the belts aren't stuck to the pulleys,from sitting,or that some thing isn't grounded properly.
