Question about glow plug/light
After patiently waiting for that little "pigtail" glowplug light to go out, does that mean that the plugs stop heating up..or does it mean that the plugs are hot enough to start it and the plugs keep getting power?
Reason for this question: Another thread mentioned that some folks cycle the key assuming that when the light goes out, the power to the plugs has stopped and cycling heats up the cylinders more for better cold weather starts.
I have no idea which is correct, but, considering how complex the whole freakin' electronics system is, I m guessing there is really no need to cycle the key to help with cold starts, the 'puter with all of it's vast wisdom takes care of this situation.

It would only help it start better by cycling the key if your gpcm/glow plugs are defective or near death. When I changed all mine out, the research I did to make sure I put the best ones back in, was something like this. The factory plugs turned out to be the best, duh. They are rated to heat up to max temp within a certain amount of time. Can't remember what the time was on the factory plugs...

i disagree, there is a 2 min timer, wait 1.5 min then cycle the key the truck will start better with less effort. the longer the cycle the hotter the cyclinder.

I think your opinion is worth more than 2 cents...just by inflation alone
