If you drop the column as described, then you can reach in and unplug the ignition switch and look for fried terminals on the connector. If the connector looks okay, then you probably just need to adjust the rod.
Depending on if your column is tilt or non-tilt and what year truck, the switch might look different than the link, but the procedure is basically the same. The main thing you want to do is eyeball the connector pins.........
