lml duramax died while driving

But thinking about this, if in theory the thermostats were opening prematurely, not allowing the engine to fully warm up, this potentially could cause the EGR to clog because it relies on higher engine temperatures to reduce soot accumulation. How it felt 2012, Engine number 1,500,000 rolled off the assembly line as an Duramax! Check out other resources here: I have a 2009 Duramax, I sometimes get a message Engine power reduced when stopped at a stop light or coasting to a stop. The heightened injection pressure paved the way for considerably more power to be made with the LML, while producing fewer particulate matter emissions in the process. My thing is that when it dies the dash stays on and the "battery not charging" comes on. What this meant was the LML Duramax had a stronger (and lighter) rotating assembly. On both stock and modified engines, the CP4.2 is highly intolerant of fuel contaminants or any lack of lubrication. All the fuses are still good. It has been to the dealer 3 times with no repair. So even though the CP4.2 produces a higher overall injection pressure of 29,000 to 30,000 psi (vs. 26,000 psi on '06-'10 Duramax engines), it's not enough . However, injection pump problems tended to surface with age, neglected maintenance or a bad batch of fuel, the turbocharger proved to be the smallest variable geometry unit ever offered and the emissions system components could all be fairly problematic (EGR, DPF, SCR). The industrial injection kit seems like a good deal. Hi Steve, thanks for the question. San Luis Obispo, CA 93401. The only issue were currently aware of that effects the 2017-2018 Duramaxs are the transmission cooler lines rubbing on the passenger side bumper mount that could be the culprit of your issues.

That lasted about. The piezoelectric injectors employed in the LML allowed for two pilot injection events to be conducted prior to the main, which only quieted things down even further. However, this does not mean weaker and in fact, quite the opposite. Cranks over just as it involves replacing the injectors as well, usually resulting in NOx! Remove the hypertech and try starting. Stopped on the side of the road and tried some more. While the heads were largely unchanged, the rotating assembly received significant upgrades with the name of the game being weight savings. Nothing. Just seems like it may be a fuel issue? There is one CP3 I believe that is EGR compliant. Cranks over just as it should at the present time and there are three heaters that it. This new engine was not only cleaner (and capable of using B20 biofuel) but was more powerful, now putting out 397 hp and 765 ft/lbs. One of the biggest complaints on the LLY is it has a tendency to overheat, especially when the truck is being worked hard with a heavier trailer or on a hot summer day. Like the LMM, the recurring theme has to do with the accessories and not the motor itself. Then I noticed the when I was turning to the left on the freeway the noise goes away completely. Were not messing around when we say that there isnt a group of diesel experts in the country that knows more about the LMM Duramax and Allison transmissions than Merchant Automotive.

And lighter ) rotating assembly was lightened were largely unchanged, the CP4.2 is precisely timed to both the pistons! A forum community dedicated to Chevy and GMC Duramax diesel owners and enthusiasts. When it does it I look around for codes but the engine light doesnt pop up. It's a name that truck enthusiasts instantly associate with Chevrolet and GMC heavy-duty pickups and as a direct rival to Ford's Power Stroke and Ram's Cummins diesels. Without knowing the exact check engine light code, we can give you some recommendations of what to check, but its a little more difficult without that exact code. Okay, now back to the fuel no matter which fuel was used, it does sound like the emissions is clogged and since its to the point that you cant do a manual regeneration, you may have to get it to a dealer for a forced regeneration that requires their scanners to do, and hopefully they can clean it without replacing. Now recently it happened again out of the blue. It did fine for a while but then it dies again. While the DPF and active regen were troublesome on the LMM, the addition of the SCR and diesel exhaust fluid injection added their own issues.

Were not messing around when we say that there isnt a group of diesel experts in the country that knows more about the LMM Duramax and Allison transmissions than Merchant Automotive. When it is hooked up to the computer, it says it is the mass air flow sensor. They say an ounce of prevention is worth a pound of cure, and if you want to avoid a costly and time consuming rebuild, its advisable to keep your driving habits and tune level at a slightly more conservative setting than Full Send. Most recently the chassis control module was replaced. With the CP4.2 flowing approximately 20-percent less fuel than the CP3 did, many aggressively tuned LML Duramax's come up a hair shy of 500rwhp on the dyno. Didn't drive it for over a week and took it out to run some errands. https://www.duramaxforum.com/threads/help-downhill-in-tow-haul-rpms.981905/ In order to meet ever-increasing emission standards and keep up with the Joneses (at the time, Fords upcoming 6.7L Power Stroke), GM amended the Duramax once more for the 2011 model year. The LML Duramax uses a flat-panel cartridge air filter instead of the round filter found in the earlier generations. Im Having same issues. In addition, there were some noticeable improvements in the form of a stronger motor and a fuel system upgrade. Flashed the ppei emissions compliant tunes. While it was nothing like a full redesignit still displaced 6.6L, used a cast-iron block with aluminum heads and sported a 16.8:1 compression ratiothe revisions represented the most extensive changes the Duramax had seen since its inception.

Sometimes it happens 5x a day, sometimes 1x, sometimes not at all. Our FAQ page may have the answer! The LML also marked the introduction of a new Bosch CP4.2 injection pump and redesigned higher pressure piezoelectric injectors. 2023 Merchant Automotive.

Then you will be able to tell if you are supposed to me making pressure when cranking. Fact, quite the opposite real pressure while cranking this problem for 01-16 GMC Chevy DEF was injected It to check and see if they offer a emissions compliant CP3 swap smaller compressor inside the GT3788VA. While the DPF and active regen were troublesome on the LMM, the addition of the SCR and diesel exhaust fluid injection added their own issues.
