So i was just online for two hours and i found a thread kn the other site that said if i have 12v at the ign side of the relay then i just need to ground the white terminal on the relay and it will turn on the glow plugs, so i did that and the relay clicked and hummed like it used when heating the plugs.

So does this mean i need a new controller? Should i just run a push button? I just replaced the controller last summer. Tho is it possible i coukd of fried it when i hot wired the truck? When i was running the power wire in there was quite a bit of power going on and off quickly and i think maybe could of fried the controller

Do you have a way (multimeter) of seeing if there is power to the gp's when the relay clicks as you short wire it? If not, pull a glow plug and see if it is heating.

Glad you go her back in shape!
(For once the glow plug controller *really was* the problem! Doesn't happen much...)
