Having the same issue.  Also an Auto Service Tech.  Power from starter relay to pull-in/hold-in winding will only light a test light for a second or less when the no start occurs.  During a normal start it lights up for 2-3 seconds and obviously starts.  Since I have a test lead to the starter solenoid, I can jump it to positive and engage starter manually.  When vehicle won't start and I jumper the starter, IT WILL NOT START.  The last time it happened I went to grab my DVOM in the back of shop, started.  Fire trucks are red !  It is very intermittent.  At least it is my wife's vehicle and it usually starts if it sits for a few minutes or randomly wants to.  I have cold soaked it, hot soaked it, scanned PCM, etc.  Other than the short burst of light and the fact jumpering starter doesn't work, I am at a loss.  In my mind it is either the switch (wireless ignition node) OR pcm.  Anyone else figure this one out yet ?
