your still under your powertrain warranty so take it in. The most you sould get charged is 100.00 for your diesel deductable. there are so many things this could be its hard to guess ove the net. if its running fine and not smoking dont imediatly think you have bad injectors.
when is the last time you changed your fuel filter? air filter? did the truck derate and go into "limp home mode"? or did the light just come on while driving after the truck was up to temp?
unlike some internet durimax kings i work on them almost everyday and have since 01. ive had that engine scattered and put back together done 1000's of injectors so get the code and let me know if you want my 2 cents.
04 is a good year, has the new style injector for that engine (lb7) and do not see to much of them.
happy truckin
This was done back in 2003 when I had bought the machine new in 2002. It was running fine at the time of discovery but within the course of 10 - 15 miles, I knew it was off. I travel more miles in a week than do most in 3 months. Trust me, I know all there is to know about this issue (other than being the mechanic as yourself, in which I am totally ignorant), the TSB, and the GM extended warranty. I wish we had a good mechanic here. The hicks where I live and even in nearby Knoxville, TN are about as trustworthy and experienced as nothing at all. It's not an option here. Most all of these folks are gasser and shadetree mechanics.
I finally found a mechanic in Bloomington, Illinois on my third failure (as I travel all over the US to work). It failed at 36K, 54K, and again at 68K.
I'm not sure what one would not understand about diesel dumping like this...(in the pic).. LOL... I mean, what else would you think? It was failed injectors that further cause this result. And with that said, I need not have to tell you that this strips all of the cheap-@$$ coating from the entire underbody. Ask them to replace it? That is another joke on me to think GM would do that.....
These are pics of the last time the system went down. No light came on, no smoking guns, not whistles..... I knew the truck was not performing at peak, when I looked at the oil pressure gauge and it was down significantly, thus the engine was not making pressure. The tranny did go into limp mode. There was no need for a temperature light to come on. It wasn't overheating.
One thing GM under-estimated about this not so fine engine is that I drive a truck like I stole it. I don't abuse one as such but I do expect it to perform, just as my always reliable Honda Accord. I have used this truck beyond its capacity, leaving me still with a desire for a 500 HP Cat diesel and the T2000 series tranny. Poor old GM. They don't get it. No GM stock in my portfolio.
At that third time the dealer decided that they would enact upon good faith as was directed by GM and replace all 8 injectors along with cleaning the entire fuel carriage. I replace the fuel filter as required by service intervals, but it's a crying shame that this product will not hold up to the price tag.
At that time I had it repaired, and brought it back to TN as I continued to travel in the Honda while working in other states. It has sat mostly in the garage with less than 20K miles on the new iinjector rebuild, but I do use it weekly. From that last rebuild, there was a remaining oil leak. It got worse, and now I am in the process of finding a mechanic to fix it. It's not an engine leak, so I suspect a seal near the converter or the block. I'll get it up on a rack next week. I talked to a mechanic a few weeks back and he said the problem now is the availability of the injectors.
Please don't take this as a GM bashing post. It's not. I call it like I see it.
Have you ever seen a mechanic let the air out of $800 set of Michelins, crushing the sidewalls for days (as they kept my truck hostage for 3 weeks waiting on parts), in order to get his big @$$ into the engine compartment?
Mostly, I'd like to thank you for the time and consideration of this problem. I appreciate your thoughtfulness. I will keep this truck a few more years then trade into a new one again. Or not.
Maybe look into the 08s. I like to trade on even year models. It's an obsessive compulsion of mine, among many others... LOL...
