Ignition issue

Hello all, I could use some help. In my 1990 f150 I turn the key forward all the way but the starter does not engage. The key does not spring return.. I know something is broken but I just not sure what to fix. Cane anyone give me some advice? I did search but I didn’t see anything that matched. Thank you in advance.

Most likely the actuator(the thing that connects the key tumbler to the ignition switch) has broken. Not a fun thing to replace. There are some good write ups on the internet on how to replace it though.

yup, broken ignition actuator. $15 part, but takes two - four hours to replace, depending on your level of mechanical ability.
here is a very good writeup on how to replace it:

Hi, thank you for the info. One change, the key turns freely and does not turn on the power to the vehicle. i should note too that i had to install a starter button becuase when the key went wonky it no longer engaged the starter. Does this change things?

not really, it could still be the actuator.
but before tearing it apart, try reaching up the top of the column and feel for a small 1/8 inch rod. this goes from the actuator down to the ignition switch on to of the column in ht area of the brake pedal. if the rod moves through the whole range of key turn, it may be a bad ignition switch

what i do when suspecting the switch or actuator is drop the ignition switch. if i remember correctly it is two bolts, 7/16 wrench. then i remove the rod and work the switch with a screwdriver in the rod hole. if it works in all positions and the plastic/aluminum connection is tight, then it is up in the top of the column and most likely the actuator.
