Hi,
When checking power at the starter, is it the smaller wire you checked? Also, I read back through everything and noted you mentioned starting it in neutral. Are you sure the neutral safety switch isn't bad? Are you able to get it into park now?
See if this link helps in any way:

Next, can you turn the engine by hand (with a breaker bar on the crank pulley bolt)? I ask because if you have power, a new starter, and only get a click, could the engine be locked?
If you can turn it, check to make sure the ground between the battery and engine block is clean, tight, and not corroded.
Let me know.
Take care,
Joe
