Does the positive battery cable at the starter have twelve volts both with the key off and key on start?
Also, the starter already ground to the block by the bolts that hold the starter to the block, so that rarely is a bad ground unless of course the bolts are loose or there is paint on the starter mounting block surface. The ground that you should be concerned about is from the block to the negative battery post, so you could connect a jumper cable in between the block and negative battery post to rule out that ground.
