Glow plug light not coming on/ No start
My 1992 f250 IDI was running fine and seemed to have a little trouble starting in the moring when it was the temp was around 40 degrees, but just the other day I went to let the glow plugs warm up but the light didn't come on and when I tried to start it would crank but not start. All the lights are working and I have checked the main fuse for the glow plug controller (20 maxi) but it was fine. About a month a go replaced the starter relay (near the passenger side batttery) and put in a new ignition switch (the key was getting stuck) MAYBE A BLOWN INLINE FUSE OR A BAD glow plug CONTROLLER ?????
You guys really know your stuff and you have helped me a number of times
I was hoping someone could help me out one more time.
Thanks in advance,
