Updating both threads: Every single glow plug from this truck failed the continuity tests. Completely open circuit on every one of them. I thought I was testing them incorrectly until I went and got the other 8 new plugs (I bought 16 new ones to have more on hand) and they tested perfectly.

The glow plugs I removed from my system look exactly like the "non-swelling" Swellman's that I bought. They even have the same numbers on them. They were swollen, drooping, and had burn outs. Whether that is due to improper starting procedures or the Nartron EESS, I can't say. But I did...

Why are you replacing the steering column? I'm glad to hear yours was as successful as mine was. It's interesting watching this work. Before I would get a wait light for at least 5 seconds every time I turned the key. With the new system, I illegally drove to the store and a little bit...

You are welcome, and good luck! I purchased the kit from HummerPartsGuy.com, item 01-542-7901.

Success! S3 EESS kit installed and all glow plugs replaced. The existing glow plugs exhibited all conditions. One was drooping so much that it required pliers, three were swollen up but only one of those required pliers to remove, a few had pitting and a few looked fine. None broke off in...

You are a pretty bad (good?) influence. S3 EESS kit ordered. Thank you for your guidance! :tinkerbell:

Thanks guys, I just ordered more plugs because I'd like to replace them anyway if I take them out to get everything on a good maintenance schedule. If that fixes it, I'll hold off and get an S3 EESS at a later date, possibly at the end of winter when glow plugs aren't needed every day. I'm...

I believe you. I just have no idea what I'm talking about so I didn't know if my truck already had the S3. :) I'll pull all the glow plugs when I get back from vacation. I'll likely go ahead and order new ones and look into a new EESS. Do you know what year the S3 was standardized?

The white smoke does go away. I will check the GP voltage on more than just the one. I did that troubleshooting on a lunch break so I was short on time. How long would you say the glow plugs should stay on? Being a 2005 truck, I think it's got a green label EESS already.

So my M1123 is having trouble starting when it's cold out. I checked the cold advance circuit and everything is working the way it should. Manually hitting the throttle after the wait light goes off is done regularly to engage the cold advance plunger since apparently the electrical system...
