Another misdiagnosis by the village idiot. Seems My glow plug controller is toasty. So, manual pushbutton on the dash when I wire the truck. Easy enough. Truck is still sketchy starting on 12v, starts on 24v everytime. Edit: could my forays into the world of 24v have killed the controller? not that I really care that much, just wondering so as other people will know to expect controller death if they try it.
