So guess what? Popped the hood, grabbed a light and looked back at my stancor GPR, and it was cracked. A quick turn of the wrench and now the truck obeys the ignition. Thanks, guys, i would have never figured that out without you!

Now to order another GPR

I have never heard of anything like that! With a fleet at work, six 99-03's, the rest newer, that's a first.

Would a shorted glow plug relay back feed current to whatever shuts off the fuel?
