Winter embarrsment

[7.3powerstroke2000]

After school, I went to start my truck, and it would just crank and crank I stopped recycled the key. Did the same thing. Did it three times. Then started praying. It finally started. It rolled the white smoke out the stacks for a few seconds. When i was cranking on it, it would blow white smoke too. It's done this before but only when I didn't plug it in over night. It was like in its 20's today. Last winter I never had this problem. This is really irritating. I put two new battiers in it a few weeks ago. Now, I don't want to shot gun this. So if anybody can give me an educated answer I would really appreciate it.
Thanks

Check your GPR, if it's ok then it's probably glow plugs...

I am a freaking retard! How do I switch it over to to the 99 to 03 thread?

I've been thinking about that. how do you check it? multi-meter?

Agreed. The white smoke makes me think so.

GPR: 1) If it's drawing current, you'll see the volt meter on the dash dive to left after you turn the key on. 2) You can by-pass it by jumping the terminals. If you bi-pass it and it starts right up, you have a gpr problem. Careful doing this though, you'll be throwing sparks if you try it.

If it does test out to be the gpr, look into the Stancor 586. It's a better replacement.

Oh, thanks to Superduty4x4 for this post on testing gp's:

You can ohm check the GP's without pulling the valve covers. The connectors are arranged as such:

GICIG

G = glow plug
I = injector
C = injector common ground

To test the glow plug measure ohms between each G pin and a good ground. Should be between 0.2 and 2 ohms. Open (no resistance, 0 ohms) means a bad glow plug. Just touch the pins inside the valve cover connection with the lead on your multimeter.

I don't think the volt/amp meter will move on a Super Duty. All the gauges are like idiot lights. Just take a test light and test the relay. Turn the key on and if both sides (large post) of the relay cause the light to come on, relay is good. If only one post causes the light to come on, bad relay.

You might want to grab some PowerService DieselKleen in the white bottle. It has anti-gel stuff for the fuel. Should be able to get it at Walmart!

Troubleshoot with this first though: Winter Operation, Hard Starting, Hissing Sound Etc...
Definitely sounds like a GPR problem, if not it's your gp's.

If it's your GPR, this will inform you on what to do: Stancor Relay Mod!!
