Sticky Key Cylinder
My ignition key is very sticky going from run to start. I have to turn it back to the run postion manually or the starter stays engaged. My truck is a 1990 F250 without tilt steering. I have the steering wheel off and I've sprated "PB Blaster" into the plunger assembly located inboard of the key/tumbler. It seems looser but can I disassemble this further to get inside this thing? I suspect old/hardened grease is fouling the spring mechanism.
I wish I could attach a photo.........

Common Ford Problem
Will a Haynes manual tell me how to get to the spring to replace it? Can I replace an assembly to fix it? I have the 7.3 idi Haynes manual but not the one for the truck body.

its a total crap job. theres a gear selector that the key turns, that moves a pushrod down the center of the column and that activates the switch. if your not careful you will break the cast piece and you gotta strip it all apart. i had to do that when i got my truck. huge pita

PB Blaster is a very good penetrating oil, but not very good as lubrication.
The PB Blaster will cut the crap loose, but then you need some type of lubricant to keep it loose.
White lithium, some spray oil like 3 in 1, Marvel Mystery or any of the many others out there.

I discovered that quirk this winter when my turn signals and heater fan stopped working. I'm on a manual return system now.

Working better....
I let the assembly soak overnight in "PB Blaster" then sprayed it down with white lithium grease this morning. I reassembled it and it works better......not as well as I'd like but it returns to the run position after the truck starts.
Sheesh......you'd think a twenty year old ignition would work flawlessly!?
