Ford starter solenoids stick sometimes. Especially the cheap replacement solenoids. I always have a 13mm wrench in my pocket in case so that I can smack the top of the solenoid to unstick it. The other mechanic carries a small ball peen hammer. The contact in the solenoid can weld itself on from the current. After fixing your solenoid problem, the no start problem is a no spark problem? At the solenoid is the ballast resistor bypass wire. It dlivers full voltage to the coil during cranking. If this is bad, the engine will only try to fire for a split second after cranking but before stopping spinning completely. If the ballast resistor is bad, the motor will only try to fire during cranking the starter. If the ignition key was left on for an extended period of time without the engine running, you might have burned up the coil.
