I was cranking my truck on and off trying to adjust the timing, and i cranked it and it wouldnt stop turning over, so i unhooked the battery real quick. today i tryed changing the ignition key switch and still does it. If anybody knows whats going on i would greatly appreciate it.. 88' f150 5.0

 

Might be stuck solenoid, tap it, if it does not stop, pull the small push on wires and see if it stops, if it does switch on bottom of column might be bad.

 

What solenoid, the one near the battery or the starter. What switch at the bottom of the steering column, also?Thanks for the help

 

The solenoid by the battery, and the switch on the bottom of column sometimes goes bad.

 

I agree, the switch on the column he's talking about is the Ignition switch.
