Wait to start light

[kreepin2g]

I think I need to replace my gpr cause when my truck sits at work all day in the cold not plugged in it has alot of white smoke come out after I wait 30 seconds to a minute after the light goes out. So my question is if I wait for the light to go out and turn the ignition off and do it again will the gpr fire the glow plugs again to help heat the cylinder up more?

the glow plugs stay on for 2 minutes. If you listen you will the relay click. It stays on after the light goes out

I hear a buzz like noise when the light goes out. Very quiet though.

the buzz you hear is probalby the electric vacuum pump. it kicks in when you turn the key on.

White smoke is normal, mine does it kinda bad when its cold. Whitish/blueish smoke. Like others have said, the GP's will stay on up to 2 minutes even after the light is off.
