CEL showing all (?) glow plugs bad?
More confused now. I cleared the codes when I read them. CEL went off. 20 degrees F here this morning and the glow plugs functioned fine and no CEL after start. Appreciate the CEL being off, but what caused it in the first place? Don't recall jump starting anything or any other issue when...- Old_Salty

CEL showing all (?) glow plugs bad?
Getting the codes for bad glow plugs - P071, P072, P073, etc. - saw all but for cylinder 5. That one may have been there as well. Truck starts well in the cold weather so I am doubtful of the codes displayed. Wondering what would cause all to show bad.- Old_Salty
