Re: Electrical Ground Issue - Starter
If you are following the proper jumper cable procedure, with the last negative connection to something on the block, it would seem to me it is cranking from the second battery. This kind of implies, there is something intermittent between your battery negative and the starter, but you have replaced most of it.
I have a cheap little KD current meter 2423, I would lay that across the cables to see if the starter is drawing current when it doesn't crank. Measure the battery voltage while in the start position and not cranking.
You could also make up something to to see it 12.6V is making it to the solenoid on the start terminal, but that seems OK because it always cranks, when jumped.
It could be that positive battery terminal, because you touch that, and the key every time you actually jump it. I believe everything else but the starter, runs through the little wire on the positive bat terminal.
