Granger, yours is a wide open question and sounds mostly starter performance related, but may involve some ignition or other problems, but I will just address slow or weak cranking.....

The FIRST thing I would suspect is the battery, insure theres electrolyte above all the plates and that no cells exhibit a gray or milky color indicative of a weak cell and next give it a good slow full charge and better yet have a shop LOAD TEST it or try a know good substitute battery n see what happens???????????

Next, if none of that helps much I would remove, clean n wire brush shiny, n reattach each n every battery n starter n starter switch n ground cable conenction n see if that helps. If the ground cable is attached to any thin or rusty sheet metal, maybe try it to a clean solid bolt somewhere?????????

If still shes a slow cranker with a good battery n all good cables n connections, I would try to by pass the starter switch by using jumper cables to jump around/across it or just jump the hot ungrounded battery post direct to the starter n see if she cranks better then????? If by pass jumping around the starter switch improves cranking, I would suspect the switch.

Turn the lights on when cranking and if they dim wayyyyyyyy down badly and/or the voltage drops drastically, I suspect the starter motor itself, but if theres not much change in voltage or light brightness, then I suspect the starter switch more.

FINALLY if the battery,,,,,,,,all cables n connections n grounds,,,,,,,,the starter switch are allllllllll okay but she cranks weak n slow, then I suspect the starter is at fault, maybe it just needs new brushes or the armature is dragging or otehr problems.

Sounds like it may simply be a cable or bad connection problem, so try that and check the battery condition first.

Let us know, best wishes n God Bless
