Engine turns over slow. Earthing issue?

When I first fitted it I went to start it and it fired up okay considering the exhaust wasn't fitted and timing wasn't set. Then winter came and I hadn't looked at the car. Now I can't get it to start, it turns over real slow, even when jumping off another running car. If I remove the plugs it improves but still very slow. I have ordered a new battery as the old one was shot anyway and some new earth straps. Could this be an earth issue though? Or something else? Thanks!
