Had a similar problem. When I would get a no-start when turning the key, I found the small wire that goes to the starter solenoid was not getting any voltage. When it does get voltage, it would always start. The solenoid voltage was not passing through since the small wire was supposed to provide the voltage to close the contacts in the solenoid. I never figured out why I was not getting voltage through that wire at times. I just lived with it.
Had the same issue on my workhorse and may have the answer for you.
On my 2005 Workhorse there are not one but two "Solenoids" one is called a Pilot Relay. NOTE this same thing was done on one of my daughter's cars Just so you know.
The car had it put in by recall. Seems ignition systems were catching fire due to the high current through the starter solenoid so they put in a pilot relay.. After sale. On my Workhorse they did it up front (Also a GM designed system)
I pulled into a gas station last April and when I went to re-start so I could pull ahead a few feet. A sharp click (not a clunk not a rattle) well. no tech handy to waste money on so I had to do it myself. Since the CLICK is the sound of a relay (Clunk is the solenid) I started at the main chassis fuse box. Identified the relay on the 1st try Pulled it, Cleaned the contacts and replaced.
