Thanks for the reply. I can check the starter by jumping the relay, but another head-scratcher is why do i not get any lights on the dash when in the run position. And, as I said chek3ed all the fuses.

a recently purchased 1999 silverado with the 4.8 engine was acting like loose connections somewhere while driving. The brake light would come on, then go off, other lights on the display did the same. Truck still ran tho. no codes on the OBD. Put in a new wiring connector and ignition switch. Now nothing! In the On position, no lights on the dash, turn to start position and the check engine light comes up but nothing else. Checked and verified all fuses are good, looking for a good, simple wiring diagram for the starting circuit. Or for some knowlegible suggestions.
