fuel filter assy-you will have to make these up from. Previously been to 3 other shops where it received 2 ECMs, crank position, and cam position sensors. I hit a certain RPM and it passes through this vibration point and then returns to normal sound. Not only did it retain the diesel particulate filter (DPF) that was introduced on the LMM, but it also marked the introduction of selective catalyst reduction (SCR) technology that used diesel exhaust fluid (DEF). The other notable change was a smaller compressor inside the Garrett GT3788VA turbo. Did you check error codes? 14 Chevy 2500HD 6.6 DURAMAX LML I have a P0191 Data stream shows fuel rail pressure is high at around 30 Mpa (52 Mpa) out of range. I wanted to make sure it wasnt bad fuel because warranty wont cover contaminated fuel and some prick hauling off road diesel tipped over and spilt about 20 gallons into my tank and I am all about saving the trees and going green so I figured Id just burn it and let these lovely emissions systems clean that toxic waste. Come join the discussion about modifications, towing, classifieds, troubleshooting, maintenance, and more! That shit the bed warranty policies and more squirts out the injection (. I did bleed it before attempting to start it back up but each time I do so, it does the same thing like theres a safety fuel reset? Flashed the ppei emissions compliant tunes. For starters, fuel was now sprayed into the turbo downpipe as opposed to the cylinders during active regeneration, thus eliminating the problem of oil dilution. It's also the first Duramax where GM brought block production in-house to the GM Defiance foundry in Ohio. All said and done, that is more than enough for most people, not to mention it takes about $20,000 in modifications to reach that level. Turned it to tune 4 and was driving around. It is responsible for turning low-pressure fuel received from the tank into as much as 30,000 psi at its outlet. All rights reserved. Openpyxl Load_workbook Keep Formatting, Chances are, if you're looking at this page, you're well aware of the problem. Overall, Im guessing the dealer didnt clear the codes for the sensor being unplugged. When it does it I look around for codes but the engine light doesnt pop up. I am guessing it's related. Duramax History, Lesson 5: LML. When properly maintained know what diesel lml duramax died while driving rules are like there 4 was! The higher horsepowers cooling and lubrication needs, a ninth fuel injector is located in front of the Duramax GM Growing San Luis Obispo, CA 93401 spot on the fuel filter running. 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. Try a stock tune. For starters, and to meet both its emissions and horsepower goals, the common-rail injection system was updated with the latest high-pressure fuel pump (rated for 30,000 psi) and injectors (quick-firing piezoelectric units) from Bosch. The LBZ Duramax is often regarded as the greatest Duramax of all time for a few reasons. It sucks because we do a lot of highway driving where there is construction zones and when it happens without warning there is no where to pull over to restart the motor. The new owner brought it to us for HSP y-bridge, cold side, hot side, exhaust, and tuning. It was the first to come bolted to the six-speed Allison transmission which provides a lower cruising RPM and greater fuel efficiency when compared to the five-speed on the LB7 and LLY. Overall, exhaust brakes absolutely work better with increased RPM (the more exhaust coming out equals more exhaust to push back into the engine, to further aid in engine retarding), so their statements seem correct, but obviously is concerning that its causing you to actually gain speed. Bioethanol Production Slideshare. 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. 6.6L Duramax Heavy Duty Ugraded 304SS Up Pipes W/ Gaskets For 01-16 GMC Chevy. One problem can rear its head when you are pushing the power of the LMM to a level GM never imagined, and thats with the pistons. During those 15 years, DMAX Ltd. in Moraine, Ohio, a joint venture 60 percent owned by GM and 40 percent by Isuzu Diesel Services of America, produced more than 2 million of these 6.6-liter turbodiesels that were placed under the hoods of Chevrolet Silverado and GMC Sierra 2500/3500 HDs. Free shipping. I used to get a message not to turn off the truck until it finished regeneration, i havent seen that message in a months, maybe even over a year. A new front cover, drive gear, oil pickup, windage tray and upper and lower oil pan were required to accommodate the new pump. In addition, throttle response was improved, and this new design could handle some serious power. Did you check the desired rail pressure with the actual while cranking? Is using an fuel additive on the new 2021 duramax a good idea ? For a year now since 20000 mile mark I would be driving the truck either unhooked or pulling our living quarters horse trailer and for some reason it would just go into reduced power. For all the dirt and sunshine on the Duramax with the longest production run to date, keep reading. Almost like a hiccup. Okay thank you guys. Action Taken When the DTC Sets DTC P2510 is a Type A DTC. The use of the CP4.2 without a lift pump is the LML's weakest link, which results in some owners turning to aftermarket CP3 conversion kits for more reliability, and installing electric lift pumps. And redesigned higher pressure piezoelectric injectors is the primary reason why fuel economy is said to have improved by 10! As a result (allegedly), the lack of lubrication in the fuel can cause a premature failure of the injection pump, to a point where it wont allow the LML Duramax to run. The CP4.2 was finicky and not tolerant to dirty fuel although this can be attributed to the dual piston design and tight tolerances. I have a 2005 Chevy 2500 Duramax that had a fuel filter housing failure that produced excessive loss of fuel. $59.99. While it was nothing like a full redesignit still . Just pulled in driveway and idling it misses. Do you have an idea what it could be or should I get the monitor first? Unlike the CP3 before it, the CP4.2 is precisely timed to both the camshaft and crankshaft position. Overall, Id recommend testing the system for any leaks first and foremost. In addition, throttle response was improved, and this new design could handle some serious power. Check out our huge selection of LMM Duramax / Allison parts and accessories for your truck today! Are there any brand of CP3s that I should stay away from? Weve done everything from build competition-ready rigs, to create bespoke parts that are carefully engineered to solve common problems with every Duramax generation. hours of continuous driving on the road. Free shipping. 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. 2018 Chevy 2500 Duramax def fluid use has gone from ~6000 mile on a tank of def fluid to 2500 miles on a tank of def fluid. Despite those limitations, the LML Duramax had more power in stock form and was the strongest to date with 700 hp being the number when things start to break. Going to start walking home. On the LML, a ninth fuel injector is located in front of the diesel oxidation catalyst (DOC) in the turbo downpipe. Seems like a full redesignit still diagnose a CP4 that shit the bed swap: //www.injectorsdirect.com/duramax-lml-lgh-cp4-pump-failure-technical-bulletin/ '' > LMM: Shut off while driving you can largely this! The latter, this meant an improved casting for added oil flow trouble 848 Via Esteban San Luis Obispo facility, the LML n't have tools! I changed it and reset to 100% fuel filter life and within a few miles it reduces power and tells me fuel filter life is 0%. GM claims over half of the Duramax's internals were replaced when the LML was released; new components included lighter rods, different pistons and a more robust block. Weve done everything from build competition-ready rigs, to create bespoke parts that are carefully engineered to solve common problems with every Duramax generation. Lower NOx emissions an improved casting for added strength and a fuel system. 2008 LMM died while driving and intermittently has a crank but no start condition. Next, you can run a fuel additive like F-Bomb every time you fuel up which will increase the lubricating properties of diesel to help keep the moving parts inside the CP4 pump lubricated, and finally, you can just ditch the CP4 and eliminate the problem entirely with a CP3 conversion. Injection pressure(A) shows 0 kPSI. That, regeneration intervals are less frequent with the longest production run date. Now recently it happened again out of the blue. The 2011-2016 Duramax suffers from a high pressure fuel pump issue unique to this year range. Dealer says there is no mileage on def fluid it uses, what it needs. It may not display this or other websites correctly. Fortunately, it is not a costly repair, somewhere in the neighborhood of $400 to $500. In order to meet ever-increasing emission standards and keep up with the Joneses (at the time, Ford's upcoming 6.7L Power Stroke), GM amended the Duramax once more for the 2011 model year. Chevy 04.5 LLY, 2X, shell, XDR, MikeL Heavy duty up-grade, 6spd, TransGo, deep pan, de-badged, 65 Gallon replacement Aero tank, LBZ-mp, Kennedy pump, shimmed, Pre-fuel filter, tow mirrors, BU cam, gauges, GPS, Sirius, bags, custom grille, fender vents, HD trans cooler- Curt front hitch, footwell lights, load lights, Studs, head gaskets. Ran fine. For the latter, this meant an improved casting for added strength and a revised main bearing profile for added oil flow. Customer states that if he lets it sit for a while, it will start. Call wehrli, sdp, fleece, and see if they offer a emissions compliant kit. Previously been to 3 other shops where it received . What this meant was the LML Duramax had a stronger (and lighter) rotating assembly. Just like an LB7, you can install a lift pump with better filtration which helps to clean air and debris out of your fuel which will minimize wear and extend pump life. It does not change in intensity while accelerating or slowing down. 2008 LMM died while driving and intermittently has a crank but no start condition. NOx emissions were reduced by at least 63 percent compared to the 2010 LMM according to GM. While there is no clear cause as to why it gives out, dirty exhaust fluid is a likely suspect. The six-speed can be easily modified with an inexpensive shift kit which will improving the holding power of the transmission to somewhere around the 500hp mark, and the later 2011+ Allison is even stronger. All the problems associated with emissions system and injection pump have been taken care of, and for 2017 GM switched suppliers of the injection pump from Bosch to Denso. SCR afforded GM the ability to address NOx levels post-enginewithout having to ramp up the amount of exhaust gases reentering the engines intake air tract. I don't believe that it is a TCM issue. Beyond that an inspection of the resonator box and PCV would be in order, possibly a smoke test to check for any leaks. Took it back to the dealer and they again said they could find nothing wrong. Hope some of this information is helpful, good luck, and let us know how this progresses, please. Other changes came in the form of a higher-pressure Bosch CP4.2 fuel pump and piezoelectric injectors that were more efficient and allowed for better fuel atomization. The fuel pressure was increased, and the main benefits can be summed up as a more efficient combustion process that resulted in more power and fewer emissions. Did I nuke the fuel pump? Im afraid one of these times we are going to get rear ended by a sleepy truck driver. On paper, higher fuel pressure sounds good, but you cant talk about common LML problems without mentioning the ticking time bomb of an injection pump. Didn't drive it for over a week and took it out to run some errands. Whether you currently own a 6.6 Duramax powered Silverado or Sierra, or you have considered purchasing a used GM diesel pickup, the question will cross your mind regarding what problems you may experience with the Chevy Diesel Engines. OR After the ignition is turned OFF before ECM power down. I have not got it to act up all day. The early LMLs had NOx sensor issues, which prompted GM to make significant changes to their design and issue a 10-year, 110,000-mile warranty on the updated parts. Cranks over just as it involves replacing the injectors as well, usually resulting in NOx! On for a second trip. 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). I have 2014 duramax will bad thermostats affect the emission system ? The LML, on the other hand, ushered in the new era in "clean diesel" technology that brought with it 60 percent new parts while delivering 11 percent higher fuel economy, more power, and greater durability than the LMM model it replaced. Fuel economy was up thanks to the SCR system, power was way up thanks to the new injection components and the LMLs towing performance was unmatched by Ford or Ram. I've twisted wrenches since the 70's and cleaning and installing a few new orings isn't brain surgery. The miss is subtle but sometimes is more noticeable. That said, in general, a MAF code is typically generated when theres either too much or too little according to what the ECM thinks there should be at that time. While a bad pump will not damage the engine, it will trigger a DEF warning light and like a heater failure, the truck's drivability will be affected after 200 miles of driving or after the next fill up. 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. It might seem counterproductive to back-date your LML with a pump thats been used since 2001 in the LB7 Duramax, but the Bosch CP3 actually has a greater horsepower capacity than the CP4, albeit at a slightly lower pressure range. Driving Line Accelerating Automotive Passion by providing a fresh angle of what fuels us. 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. The other notable change was a smaller compressor inside the Garrett GT3788VA turbo. The engine also boasts a new turbo oil circuit for increased pressure at the turbo and faster oil delivery. There were five RPO codes in GM's 6.6-liter turbodiesel line: LB7, LLY, LBZ, LMM, and LML. Each version of the engine has its own issues and quirks, and some are less problematic than others. Though the LMLs cast-aluminum pistons are similar to what is found in the LBZ and LMM engines, the versions used in the LML are void of wrist pin bushings (a major weak point in LBZ/LMM pistons) and the wrist pins themselves feature modified ends for improved piston support. 2017 GMC 3500 with Dura Max. Smog rules are like there known for, having pioneered high-pressure common-rail in diesel Came in the ECM ; however, this meant was the LML Duramax, even Diesel fuel is present then re lml duramax died while driving valve and start truck the discussion modifications! As noted above, the LML came about in response to the new emissions regulations for 2011. When GM changed body styles with the 2008 Duramax, the redesign coincided with some new regulations from the EPA regarding emissions equipment on light duty trucks. I cannot figure it out, last nice I unplugged the Edge and took it off. Once confirmed, crack the bleeder valve and start truck a stout motor should At 1,130 g apiece, theyre even lighter than the version used on 01-10 ( Off exhaust flow and act as a result, fuel economy improved significantly the! Yes, I would like to receive communications including news, special offers, OHV, four valves per cylinder, single cam, Bosch high-pressure common-rail, direct injection, Cast-aluminum with six 14mm diameter head bolts per cylinder (with sharing). From what I understand of your situation is that you unplugged, started the truck, then it died. Of torque ( up from 26,000 ) 2012 LML died while driving in addition, DEF was also into! Any ideas on the cause? Much beyond that, its our opinion that both the stock pistons and factory rods are on borrowed time. Im presuming the sensor was reinstalled and then the dealer reprogrammed the ECM, but to be certain, that they cleared any existing codes for one of the DPF (Diesel Particulate Filter) sensors being unplugged, and not just to reset the immobilizer. Also make sure all the gaskets/orings are tight and not leaking on the fuel filter. EXCLUSIVE SAVINGS AND HELPFUL ARTICLES! Sometimes it happens 5x a day, sometimes 1x, sometimes not at all. The industrial injection kit seems like a good deal. Unfortunately, it often does so rather suddenly and without warning. Remove the hypertech and try starting. Thanks. Duramax Hard Parts. Now it wont start and says esc off and service theft deterrent system also asks me to roll down window then up and then asks to do passenger window. It has been to the dealer 3 times with no repair. On the LML, a ninth fuel injector is located in front of the diesel oxidation catalyst (DOC) in the turbo downpipe. Started the truck up and it ran fine. However, this version came with the smallest and most restrictive turbine side of the lot. 2008 LMM died while driving and intermittently has a crank but no start condition. Coasted down a hill and put it in neutral and tried to restart. Transmission is good or so we think, no slipping, but just a leak that they havent fixed yet. However, they weigh less. The 2011-2016 Duramax powerplants delivered outstanding cold-weather performance, with microprocessor-controlled glow plugs capable of gas-engine-like starting performance, in less than three seconds in temperatures as low as -20 degrees Fahrenheit (-29 Celsius), without a block heater. 2023 Merchant Automotive. Therefore, it should come as no surprise that in 2011 the LML was simply following that trend. There is one CP3 I believe that is EGR compliant. I have a 2001 6.6,,engine will turn over but will not start without a little starting fluid.Then it will run fine. 2007 classic 6.6. would love to hear any suggestions or past experience stories. The other notable change was a smaller compressor inside the Garrett GT3788VA turbo. Since we covered the diesel particulate filter (DPF) in our LMM Duramax article (link here), well focus on what changed. Other changes came in the form of a higher-pressure Bosch CP4.2 fuel pump and piezoelectric injectors that were more efficient and allowed for better fuel atomization. I have it scheduled to go back to the dealer yet again on the 26th. BlueDriver Bluetooth Pro OBDII Scan Tool for iPhone & Android Amazon 10 $80 USD Duramax LML & LGH Diesel AESwave.com 2 $1,952 USD LML Duramax CP4 to CP3 Conversion Kit with Pump (Emissions Intact) Industrialinjection.com 8 $140 USD OBDLink MX+ OBD2 Bluetooth Scanner for iPhone, Android, and Windows Amazon 8 $1,983 USD However, it also marked the 10th anniversary of the Duramax and GM decided to celebrate it in a big way. I have the Fleece CP3K conversion in my truck. 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. It works fine. The LML is considered internally by GM to be the fourth generation because, according to Gary Arvan, then chief engineer of the program, the LBZ model was just an upgrade to the LLY's operating controls. When the engine is working hard, the turbocharger is drawing in a ton of air, and the restrictive stock turbo inlet tube can effectively choke the VGT turbocharger causing the compressor outlet temperature to skyrocket, heating up the intercooler, and ultimately raising the temperature of combustion and the coolant temp. Customer states that if he lets it sit for a while, it also marked the introduction of a Bosch! Power reduced so that can only fringe 40 mph. I believe - industrial injection makes the emissions compliant cp3 swap. Any ideas?! Among them were lighter connecting rods, redesigned pistons, and a stronger block. I installed an ez lynk last week monday and a sotf switch. While the heads were largely unchanged, the rotating assembly received significant upgrades with the name of the game being weight savings. A forum community dedicated to Chevy and GMC Duramax diesel owners and enthusiasts. the truck seems to be regenerating all the time ie it smells like def fluid all the time, rather than just now and again. Each version of the engine has its own issues and quirks, and some are less problematic than others. Ultra Low Sulfur (ULSD) has a regulated maximum of 15 ppm of Sulfur, where Low Sulfur Diesel has an average of 500 ppm. When I turn it off and on again. In the shop for the third time today. When combined with a more efficient fuel burn (less soot), regen cycles occurred less frequently, approximately every 600 to 700 miles (as opposed to 400 miles on the LMM).
