Sounds like low voltage/current to me. This exact thing happened to me a while back and I did most of the things you did, replaced the ignition switch and everything. Turned out my positive battery terminal wasn't perfectly tight. I really tightened that sucker down and the car came to life.

So, makes sure your connections are spotless and tight (don't go crazy though, it's soft metal). And try not to get dielectric grease on the contact surfaces, it's an insulator, not a conductor.

Also, make sure that new battery is definitely OK. Can't tell you how many times I've pulled all my hair out trying to track down an electrical problem and it ends up being something stupid like that.
