Ok.key switch was extreamly hard to turn,then would not start unless i played with sterring wheel and shifter,so then i replaced both key switch and ignition switch on collam,now 2 weeks later key switch is again hard to turn and im starting to have trouble starting engine again unless playing with shifter,truck is 84 f-150 302,auto,tilt wheel,had since new,any ideas???

 

replace the ignition/place where you put the key. never done it personally, but seen it done many a time.

 

Might try squirting a bit of WD-40 on the key, and work it in and out a bit. The pins inside could just be gummed up and not be falling back as they should. I've seen that happen a time or two.

 

I had a similar (possibly) problem a few weeks ago. I changed out the key cylinder (it costs about $3 and you can replace in 30 seconds if you have the old key and a 1/8th inch drill bit).

But, my problem was that the electrical connector under the dash had split apart and so I couldn't start the truck at all. There is an aluminum rod that runs from the steering wheel down to a sliding connector. I would say to try to take a look at that.

I have a picture I took of my truck all dissected if you need it.

But, the easiest thing to do is to go buy a replacement key cylinder. Then, put your key in the ignition and turn it to on (just before start). there should be a small hole on the under side of the steering column right enxt to the key cyliunder. Stick a small drill bit (or other hard piece of metal) in there and push. Then you can just slide out the old cylinder and drop in the new one.

 

happened to me once with my 83 f150/302/aod/tilt wheel. i put powdered graphite on the key and worked it in & out a few times. fixed it.
