Clutch ignition switch
Don't know if that's what it's called, but it is the switch on the clutch rod, right up against the firewall inside the cab. On my 1991 F150, with 5 speed and 300 straight six, I have to just about push the clutch through the floor to make this switch happy and let me start the engine. I can't find a diagram of it anywhere, and I'm not sure how it works. Does it get pushed against the firewall to activate? Would it make it easier to activate if I put a rubber washer between it and the firewall? I can grab it and move it a bit, and that seems to make it easier to engage for a while, but it always returns to the through-the-floor position soon.

When I hear that the first thing that comes to mind is the nylon bushings on the linkage under the dash are worn out. Most of the time it's the bushing that attatches to the clutch master rod under the dash. (E69Z-7526-A IIRC) but could be the "2471" base number bushings. Also make sure your firewall isn't flexing when the clutch pedal is being depressed, if it is Ford offers a firewall reinforcement kit base number 7K509 (again going from memory).
One more thing, the bar that the clutch master rod attaches to can be removed and put back in a different position, it's splined.
Good Luck.
