When you say you "jumped across the coil and starter", do you mean you bypassed the starter solenoid? The forwardmost small post on the solenoid is the one that energizes the solenoid and therefore the starter. Turning the key to "start" should send 12v through that wire. To test the solenoid, just touch a jumper from battery + to that forward solenoid post. The solenoid should click and the started should turn (or try to). Then connect a test light from battery - to that wire when it is disconnected from the solenoid and have someone turn the key to "start". Your test light should come on. If your starter turns in test one, then you know that part of your starting system is good. If it doesn't and you have a test light in step two then your solenoid is toast.

You could quit throwing parts at it and diagnose the problem.
When you turn the ignition switch to Start 12V power is sent to the starter solenoid on the fender through a wire that is connected to the small post on the solenoid that is marked with an S. If you don't see the S it is the small post closest to to the large post with the Positive battery cable. You say you jumped across the "coil" but that has nothing to do with the starter. I think you mean that you jumped across the "solenoid" which means you jumped the large battery Positive to the small S post. Remove the wire from the small S post and use a voltmeter or a test light to see if you have 12V on that wire when the key is in the Start position.

Thank you. Did all the voltage checking and found the switch to confirm the transmission was in park was not working.

OK, that would the "Neutral Safety Switch", very typical starting problem and located on the side of your transmission. Just know there is an adjustment procedure when you replace it. Check your manual, if you don't have one, should be your first purchase.
