Decided to create a separate thread for this issue. My old thread can be found here http://www.duramaxdiesels.com/forum/showthread.php?t=77913
So long story short, I had an injector fail that caused knocking. I got hosed on the replacement of the injector (dad's friend's shop, which is the most frustrating part) and the diesel tech there said I had one other injector after the replacement that was a bit out of spec and could be an issue and that the truck isn't running 100% still. The tech recommended running some injector cleaner through and see if that helps, and if not the other injector could probably stand to be replaced. I drove the truck about 20 miles and it ran/drove good, and still sounded a tad "choppy" (for lack of a better term), but better that it sounded when I first created this thread. Still no smoke or haze.
I bought some Kleen Flo injector cleaner stuff (wasn't my first choice, but was all they had available at my local parts store and I figured it was all the same snake oil anyway), put it in the tank along with a full tank of fuel as recommended on the bottle. I drove it maybe a total of 50 miles when this morning. I was sitting at a red light, and suddenly started smelling what sort of smelled like a mixture of diesel fuel and that additive, and the truck started making a few quiet, but strange sounds. Can't even really describe what they sounded like, but it wasn't a knock or anything. Drove off from the red light, was still driving fine with full power, then I yielded to oncoming traffic, tried to accelerate again and suddenly the truck had no power, started making the strange noises again, the smell in the cab became more prominent, and then died and shut off. Truck still cranked but no start.
Popped the hood, didn't see any oil sprayed everywhere, but didn't get any kind of close look because the ****ing thing broke down on the busiest, narrowest two lane bridge in the city in the middle of morning rush hour traffic on the first cold and snowy day of the year, so it wasn't really safe to be around the vehicle. I'm having the truck towed to my backyard for the next bit until I can find a good, reputable diesel shop that won't completely rip me off, and as soon as I get home I'll take a much closer look at it.
In the mean time, any ideas? I'm hoping the engine, since it still cranks, isn't totally FUBAR'd, but I wouldn't be shocked if an injector tip dropped or something knowing my luck at this point. I know the CP3s are pretty bulletproof on these trucks, but would an injection pump failure make sense? It would certainly explain the smell of diesel fuel in the cab, and if it died then the truck would definitely not start, but in theory still turn over, correct?
