There's one on the starter, yes.
There's ALSO one on the inner fender by the battery. That's the one I'm talking about bypassing. Or just jumping to the coil terminal from the battery terminal and seeing if the starter then cranks.
Don't ask me why Ford does the double-solenoid job.
Well, TECHNICALLY, it's just a relay up high on the fender.
Here's a pic of one that may be there, courtesy of RockAuto:
Take the connector that has the wire clipped to it (the one with the 6-32 thread), pull the connector off, jump it to the battery terminal, and see if the starter cranks.
If it does, it's not the wiring from there down, so you've got THAT section tested.
Next, if it doesn't, is to jump the battery and starter posts (usually done with a big screwdriver. This can cause lots of sparks, and you want to hear it just spin -don't try to start it that way!) If THAT works, then the problem is the relay there.
If, however, it does spin over with the first test, then if it's the original ignition switch, I'd grab a new one and replace it on general principles.
