posted in wrong section...you may get some help if posted in your trucks year section. welcome ...

 

Do you have any spring tension on the key cylinder when turning to the start position? If not, then you probably have a broken ignition actuator rod or ignition switch is coming apart.

 

Use a test light to see if you get power to the little wire with the push on connector (at the solenoid) when the key is turned to start. That wire activates the solenoid (power comes from the ignition switch on the column).
If you don't have power there, you have to look at the circuit from the ignition switch.
If you do have power at that little wire but it doesn't crank I'd be looking at the solenoid itself.
