1992 f250 7.3 trouble starting (must cycle glow plugs twice)
I have just recently purchased a 1992 f250 7.3l, and a week later I had a lot of trouble starting after it had sat a few days. Now when ever I go to start it, it will not start on the first cycle of the glow plugs (wait to start light) and I must cycle the glow plugs at least twice before I am confident that it will start. And also some times if it is really hot (98) and I have been driving for a while it may give me some trouble when starting. I took a a real quick look at the glow plugs and there leads were very worn and falling apart. I dont believe it is the glow plug relay controller, because I can hear the clicking noice after each cycle. I was wondering if I should take the old plugs out to inspect them or should I just replace them (I found some Bosch online for around $70) and also do I have to replace the controller.
