Default Ignition Switch problems

First off feel free to move this if i posted it in the wrong spot.

I have a 1990 f150. I can turn the key to the on position very easily but when i turn it to the start position its EXTREMELY difficult. I had to use both hands to turn the key. Its always been difficult to get it to the run position but not this bad.. Seems worse when its a cold morning but once it runs for a while its not hard to start again if its within a few hours...


Any help is much appreciated. Probably somthing simple. Just not sure if i need to replace just the starter switch or if its something else.

Also another thing is if i take the key out just barely before it in the off position i can start the engine with out the key. Or if i do this and dont realize it it kills the battery. Just a bit more info.

I replaced the ignition key switch in my 96 just before Christmas. It was doing just what you described. I bought a new one at AutoZone for about $15. It took less than an hour to replace. Now I have one key to start the truck and one key to lock the doors.

There was a TSB released in 96 recalling the ignition switch. Seems they can short out and start a fire. I'd say to just replace it.

It could be the lock actuator on the steering colunm. It's a cast rod that has a half-horseshoe in the end that breaks in two at that spot. The part number is E9TZ-3E715-B. It's a job to replace if you are not mechanically inclined.

Well this truck has been there and done that.. Been through more than one engine. I think if the ignition switch was bound to start a fire it would have by now lol. Ill look into the actuator thing and see where i get.
