if the starter is not spinning and the truck motor is running
you need to be more specific. i am going to assume you want to know in what position is the ignition switch in lock. usually it is 2 positions back from "run" but it is in whichever position the key comes out of the ignition.
Bad ignition switch.
ignition swithc could be broken, I suggest you have it looked at to be sure
Never mind figured it out
Probably a bad ignition switch.
Have you tried changing the ignition switch?
From Ignition switch run/start position terminal.
The run position is the same as when you start the vehicle. Once vehicle is started let go of the key fast.
It is probably caused by the ignition switch internals shifting (I had a similar problem before) and it turned out to be the ignition switch)
If you are talking about installing or removing the ignition lock cylinder I believe the key has to be in the run position.
To replace Ignition Switch, first you have to remove the old one. To do this you disconnect battery ground cable. Remove the upper steering column shroud by removing the five self-tapping screws. Remove tilt steering column lock lever, Remove lower steering column shroud, disconnect the ignition switch electrical connector, turn ignition switch lock cylinder to the "run" position, remove the two screws retaining ignition switch, and finally unhook the ignition switch from the actuator. Now to install the new one.Make sure that the ignition switch lock cylinder is in the "run" position. You can test for the "run" position by rotating the ignition switch lock cylinder approximately 90 degrees from the "lock" position. Hook up the ignition switch into the actuator. You might have to move the ignition switch slightly back and forth to align the ignition switch mounting holes with the lock cylinder housing threaded holes. Install retaining screws. Connect electrical connector to ignition switch. Connect battery ground cable. Check ignition switch for proper operation, including start and accessory positions. Also, make certain that the column is in the "locked" position. Then Install upper steering column shroud. Install the lower steering column shroud and tilt steering column lock lever.
A mechanism that locks the steering wheel if the ignition switch is not in the "run" position, preventing someone that is trying to steal the car by hot wiring the ignition from driving the car.
