Ford mechanic stated that glow plugs stay on same lenght of time wether batteries are really hot or not..they may crank the truck but not heat the glow plugs properly..new batteries..problem solved....my truck would start..sounded like it was running on 2 cylinders,,then maybe 4 or 5 then finally 7 or 8..new batteries...cranks right up...but I guess it could be something else...
