If it does anything when turning the key, these "Either neutral safety switch, ignition switch, or ignition tumblers" are all ok.
As suggested check the battery charge and condition. What does it do when jumped by another vehicle? Does it spin faster?
It sounds as though you are willing to "dive in", if that is the case try to borrow a decent multimeter/voltage tester or buy a Craftsman at about $20-30.

Try a jump start with good cables and let us know the result. Good luck!!!
