New battery, solenoid, kill switch, key switch but no power, no lights, no clicks. When testing, no power jumps posts on the solenoid with switch on. Any suggestions?

 

I had a no power issue with mine. Ended up being the switch on the left hand side. You can unhook the wires to it, and check for corrosion on the pins, but don't even bother taking it apart. Springs and tiny parts go flying.
I ordered a used one for $30, installed, and it fired right up.

 

Just read that you did the kill switch.
I'm not positive about the 07s, but my 06, had ecm issues. They were recalled. You can call a dealer, with your VIN and see if it has been replaced already.

 

Here's some more info on my troubles.
