waiting for glow plugs?

[panteramatt]

Is it mandatory to wait for the "wait to start" light to go out before you start these trucks? Mines a 2000 and it starts just fine rigth away. Can any damage be done?

premature wear on the glowplugs. I would not get into the habbit of doing this. Because if you are in cold weather climant you could damage other things too.

Actually the wait to start light is not a part of the glow plug circuit like it is on other diesels. The light is controlled by the computer and the glow plugs continue to be on for a minute or two after the light goes out. You can watch you alternator gauge and see it jump up when the glow plug relay disengages. A lot of folks have installed a switch so they can manually disable the plugs in warm weather to save on wear and tear. The main reason I wait is to allow time for the fuel pump to build pressure.

Your way would work how ever not every truck has a voltage meter. Some just have the idiot light like my 2002.

I didn't realize that it was all that long.

Maybe if it is a problem, you could switch to a gasser.

Of course I live in a desert, so maybe mine doesn't stayon as long as others. Anyway's I still let the beast warm up for at least a few minutes before I go.

If it is staying on for a long time you may have a bad controler or 1 or more glow plugs going bad creating the longer light?

The light ain't got nothing to do with the glow plugs.

Then why did they put it in there?

Marc told me and has posted in a thread somewhere I think that as long as the ambient temp is about 50 degrees F or higher, you do not "have" to wait for it to go off.

Thats what I figured. Does it hurt to start these up and then just go when its not cold? Im putting a remote start in soon so I can have it warm up a little.
