Ignition...switch
You mean injectors, maybe?
Do you get a glow plug light? 03's don't have the WTS light correct.
Maybe more details on what is going on? Turning over, smoking while cranking?

Sorry for the lack of details. I am get a wts light but when I turn to start it the truck will not crank. It got two new batteries last year so I know they are still good. Sometimes it will crank when it wants to and other times it doesn't.

Have you tried starting in both the Park and Neutral positions? Wiggle the gear shift? You need to check for power at the wire on the small wire on the solenoid of the starter when the key is in the Start position. Although I haven't heard much about them giving trouble, the 03's have the Start Relay in the Fuse Panel and could have failed also.
Here is a wiring diagram that will help to determine where the problem lies.

You need to determine if the DTR Sensor is actually going into the proper position. Slack in the shift linkages can cause this misalignment.

Heavy corrosion on the starter leads can also lead to a no crank. Use a volt meter and see if you are getting voltage to the main post and the silonoid.

Thanks Roland, this was what happened to mine. Went and bought a ignition slide switch and put it in, tried start in park and it wouldn't go. Then it hit me about those screws below the steering column, I found them and both were loose, tighten them up and no problems since.

Do I have to undo any parts or bolts to get to the torx screws? Thanks for all the advice.

Just remove the panel that covers the fuse box , just to give you better access.
