The key switch will not engage the starter. I have a new starter and just put in a new ignition switch. I have adjusted it all the way. I can even pull the rod as hard as possible but nothing. I can jump the starter to the battery to get it to start.

The only thing I can think of is wiring, but i dunno what wires to track down.

 

Start by checking the two red wires at the ignition switch to see if you are getting any power to them. Then I would check to make sure I put the purple wire from the park/neutral switch on the small post marked "S" on the starter solenoid. If there is no power to the ignition switch then it is obvious that you have a bad fusible link at the starter solenoid.
