Re: glow plugs not working!
If you want to send me your email via a PM, I will send you a copy of the Ford 87 Solid state glow plug manual. Might help.
One thing I would check is to be sure you have a good ground. The ground wire comes up to a double ended stud, I believe it is an intake stud. Your problem may be in the ground, or it might not. I am not sure how you tested the controller, but the guide I have may help. Does it still have the bullet style glow plugs? If someone converted it to the spade style, it will not work as the controller senses voltage drop accross the bullet type. The spade type do not work in this system. I know these sound like simple questions, but sometimes the solution is simple as well. These trucks have SERIOUS ground issues and I had all kinds of problems, including exactly what you are describing because of these ground issues.
