Default No 12v out of ignition switch

I have a 1995 5.0L 2wd with automatic transmission.

My starter stopped working yesterday.

I checked the starter relay, and I was not getting 12v to kick on the relay when I would turn the key to start. If I jumpered the relay with a screwdriver, the truck would start right up.

I followed the relay 12v line to the ignition switch and tested to see if 12v was coming out of the ignition switch when the key was turned. No luck.

I replaced the ignition switch, and no dice.

still no 12v on the Red and light blue line.

I searched around to find a pin out/wiring diagram and couldn't find too much information on the 12v going into the switch (I want to trace it all the way back).

Anyone have a clue on this one?

Go back through this electrical section - you'll have to go back months and months - and look for "good old ford starting issues".
Everything you could want to know about the starting circuit is in that thread.

As I jiggle the harness connected to the ignition switch and simultaneously turn the key to START, 12v comes through and will actuate the relay.

So, a loose connection. Fun.
