1990 f150 Ignition Tumbler Bypass
I bought a 1990 f150 straight six with the 5 speed manual about a year ago. She has been a "Trooper"! 2 days ago I finished putting gas in her before work, got in and turned the ignition and it just felt different. Everything comes on... just NO Starter Motor action! I was able to use a screw driver to jump the solenoid and get to work. I would much rather just install a push button start switch and I tried just wiring it between the two posts on the solenoid, needless to say... it did NOT WORK! Any Suggestions??? Is what I am trying to do even possible??? HELP!

When you turn the key to "start", the ignition switch on the column provides power to that little wire with the push on connector on the fender mount solenoid. That activates the solenoid and makes the starter turn.
For your (temporary) purposes you can wire your push button to provide power to the little connector and that should activate the starter circuit.

Yes you are correct! But, I do believe that inside of the steering column there is a part that breaks (seems like alot on the ford?) a little leaver breaks-off and can no longer de-press the actuator that enguages the solenoid? I believe that THAT is what has happened to me, as I can definately feel a difference in the resistence I get when I turn the key forward. I also believe that it is a major pain in the *** to replace. (just so it can break again!???) So... I already tried just wiring the switch to bridge the gap between the two posts on the solenoid... and nothing. Also tried wiring directly from the positive post on the battery, but the switch got hot in no time! So... I stopped so I could get some advice. Thanks Again!
If anyone can tell me EXACTLY where and how to install the wiring (or) if it is possible? I cannot be the FIRST GUY to NOT WANT to tear his stearing column apart? I just want to not have to get out of my truck to start it.

Do you have a tilt steering wheel? If you do the part you need should be actuator rod Ford #E9TZ-3E715-B

It took me about 2.5 hours to do this repair.
Hope this helps.

To jumper the starter solenoid you will need a momentary contact switch like this one

wire it to a relay like this one

then run the wires to the starter solenoid connect one to the starter side (I think or it may be to the small post) and the other to the battery side.
