Yep, those are good, can you tell me if you are having the same problem with both the new and old starter? If so, we should check to see if the engine will rotate by hand to make sure it is not locked up, if you cannot turn the engine by hand remove the drive belt and try again. Sometimes an accessory can lock up and stop the engine from cranking over. Please use this guide to help you:
