My uncle has a 94' turbo diesel that has recently gotten hard to start. I just tried to check the glow plug relay with a volt meter, and when my uncle turned the key on some wires started smoking from under the air intake. He said he had a fire under there before. Does anyone know what's going on there. I think I've read on here before that if something goes bad on the glow plug sysetem (maybe the controller?) that it could start a fire. Can anyone shed some light on this? We could also use some help with diagnosing the whole glow plug system. I am not familiar with the IDI system. Thanks for your help.
