when i turn my key off the truck dont turn off

did you have the ignition checked?

Yes I replaced ignition switch and nothing else also that made no differance

I have the same problem. I'm going to check out the actuator rod as I have had the solenoid, starter, key cylinder and battery replaced.

iv had the same problem and replaced the battery the tumbler and ignition switch and now it will not crank any ideas?

I think Im in the same boat. It i turn the key, the mechinism thats suppused to move the ignition switch doesnt move. Im not sure what needs to be fixed or wjat the part is called.

This is the truths Ford truck Runs great Looks great cuts off The factory dealer's alarm is turning on The truck is stuck in the middle You have it towed They find nothing wrong Yes it is working.it acts like the car is being stole and alarm cutting off motor you start it again 1 hour later the alarm is OFF and you drive it normal It will not turn on because the alarm will back on cuts off engine over time it's happens more you can not fix it but you can tell factory dealer's you no longer need the alarm installed and wish it be removed

Unplug alarm for ever

My key want turn my engine off on my 1994 ford f150

Your ignition could be broken or it could just be an electrical issue

Check wiring from the battery out make sure that all of them are not arching off anything else. I had a car start with no one in it and it had been 2 days since I touched it. The Battery positive was making the starter turn over on it's own. I replaced all wires to and from the battery.
