FYI, just got the truck back from my local mechanic. Turns out the "start,run relay" was blown. At least I got 60k miles out of it before it blew....
Do you remember what number was this relay?
Found this thread while diagnosing a similar no start / no crank issue.
Upon checking fuses, i found #31 fuse (not relay) above radiator blown. This fuse was the "Run,Start Relay Power" fuse noted in other post. FYi to anyone else working through this...
