Also, I'm not sure what he meant by the glow plugs "looked bad". The ends are always going to look bad after being in an environment like that. Most the time you cant tell a dead GP from a good one just by looking at it unless it's blistered.
Glow plugs are only used then the eng is cold. Generally speaking, after that they are shut down and do nothing.

Glow plugs are a wear item much like spark plugs or brake pads. After so many cycles they will burn out. On my 06 Dmax one burnt out at around 50K and the CEL came on a few months ago. Code? #4 glow plug burnt out. Guess what I will be doing tomorrow. :B
PS: I use no additive in my truck. There is no need in my case.
