if the engine isn't cranking at all its electrical.If it is but not firing you need to look for fuel/spark.
I think you mentioned no crank so work backwards from the engine. Start with your main ground wires. I am guessing they are on the drivers side frame rail somewhere. Back them out clean and retighten.
Next is starter. I am leaning that you have a faulty starter but make sure all connections are tight and wires aren't exposed. I would run to auto zone and get a new one. Its a quick and easy way to test it - they take returns no problem.
I think your problem lies there - you already did the switch.
Download the wiring diagram here this is my friend Mikes wiring company and the schematic is close to stock:

Good advice. I already put myself in time out. LOL.
I put a new starter on last week since I thought that was the problem as well. I feel like my connection is good since I can touch that wire to the battery and it will crank.
I'll take a look at the wiring diagram. It has to be a ground somewhere right? I just can't imagine it is anything else - new battery, new starter, new switch, etc...
