P0308 - Faulty cylinder H
P0683 - Glow plug ctrl mod to pcm

P0308{5}
Injector Driver Circuit
P1211{2}
ICP Pressure Is Above/Below Desired, Faulty IPR Valve
P1211{1}{3}
ICP Pressure Uncontrollable, Pressure Above/Below Desired
Sounds like you have a couple things going on, Bad GPR, Bad ICP, and possibly bad IDM. ICP is easy to check, just unplug it and run it without. (If it's running.) If it clears up and/or there is oil on the plug/wires, the ICP is bad. If not, it could be the IPR.
What are you using for a scanner?
What are the symptoms you are having?

I was getting a 1211 and it was the IPR, not the ICP. It gets stuck. There is a procedure to pull it out and break it apart and clean it. Worked for me.
308 could be the connectors on your valve cover.
670 & 683 I would check your glow plug relay first.

2) never take to Stealer untill all avenues have been crossed.
3) look over the questions asked and take to heart the answers given
4) she is not old, she is Mature and needs a little TLC. Give her what she needs and she will never fail you.

I'm using the programmer that was on the truck when I got it. Superchips Cortex. The check engine light came on so I hooked it up to check and that was what I got. Unfortunately this is my first diesel so I'm not real familiar with all of what it takes to fix these things. I guess it's time to do some searching unless you could point me in the direction of these fixes.

The Superchips programmer should read the codes fine. That is what I use.

UVCH - check the connectors on your valve covers that feed the injector & glow plug wires into the VC. Make sure they are pushed in. Could also be loose under the vc.

With that many miles (which it is now just broken in) you might, after you get the check engine light problem fixed, look at the threads of RR your transmission oil and filter.

Txtinct, the excursion would have a glow plug control module, in the same location as the GPR. It could be a bad GPCM or a bad glow plug.
For reference This is what the GPCM looks like
Riffraff Diesel: OEM GPCM/ Glow Plug Control Module
I have the same codes P0683 and P0670 on my excursion. I made it through last winter but had to plug the truck in a few times to crank it over on the coldest days. I really need to do this procedure myself.
Here is a thread with some useful info on checking the glow plugs.

Okay, I replaced the GPCM and that fixed the no start issue I ended up having. Got two new codes.
P0672 GP# 2 Circ failure
P1316 Injector circ/IDM codes detected
Runs fine and smooth, what am I dealing with here?
