What do you mean by "good connections"?

Your starter cable needs to be 00 gauge and your ground cable needs to be perfect. If it's one of those braided ones, install a 00 cable in its place or elsewhere if you like the look of the braided one.

What's the condition of the starter? Otiginal? rebuilt? Brand new?
