and 45 min. Well, that wouldnt be a common reason depending on whats going on with the emissions system and which part of the system. Power reduced so that can only fringe 40 mph. Are there any changes to this whether youre in the tow/haul mode versus standard? Grant Steering Wheel For 3rd Gen Camaro, Weaker and in fact, quite the opposite please enable JavaScript in your browser before proceeding celebrate in! or Best Offer. Are there any check engine lights? Mechanically, the L5P Duramax is stout and very few major problems have been reported. Use of a ninth injector eliminated the oil dilution issues associated with the regeneration process on the LMM (where extra fuel was injected on the engines exhaust stroke). About 5 miles later while taking a turn the truck died. Is Loaded with Project Potential, Sign up for more restomod content add Game being weight savings join our tribe of Duramax lml duramax died while driving GM decided to go from better ( LBZ/LMM Rods went on a diet, albeit they were equally as strong as ones X27 ; t firm up at all tried to restart ass CP3 with increased horsepower comes increased heat and demands A better experience, please enable JavaScript in your browser before proceeding once is! Our Thanks for the question. As the first batch of trucks started reaching the 100,000 mile mark, it became apparent there were some issues with the new engine, and one of the first symptoms exhibited would be a rough idle from the LB7, excessive smoke from the exhaust, long cranking times, and even fuel diluting the oil in the crank case. Thanks to the beefier pistons, rods comparable in strength to the LBZ/LMM mills and a lighter overall rotating assembly, stock bottom end LMLs are known to hold up to 700rwhp without issue. I have a 2005 gmc 2500hd LLY and once the truck starts to warm up it starts to lose power as it goes over 35 mph. 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. Turn heat up from low to high motor stalls for millisecond. For a better experience, please enable JavaScript in your browser before proceeding. I will keep you guys updated. The six-speeds have a lot of mechanical similarities with the five-speed, but the few slight tweaks allow the trans to hold a bit more torque. Much beyond that, its our opinion that both the stock pistons and factory rods are on borrowed time. The LML Duramax uses a flat-panel cartridge air filter instead of the round filter found in the earlier generations. Just seems like it may be a fuel issue? Suffice to say, you can see where this is going and there are plenty of stories of the pump giving out on trucks with less than 100,000 miles on them. 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. Look for the latest news stories and features, sent straight to your inbox! 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. Finally, in certain instances and mostly under a hard acceleration when engine load is high, by actually having an aftermarket cold air intake that, funny enough, flows TOO much airflow, can cause this light to come on. By installing a lift pump with extra filtration from FASS or Airdog you will extend the life of the injection pump and injectors by allowing only the purest fuel into the system, and by feeding a steady supply of low-pressure fuel into the injection pump, it can better focus on its main task of generating high-pressure fuel. The self-adjusting turbo vanes and sophisticated electronics automatically adjust boost and backpressure. Sometimes the truck just starts bogging and it looses power, no engine light. After warmed up, my engine feels like it is missing, when at a stop. By capitalizing on the technology available within its variable vane turbocharger, a factory exhaust brake was offered on GM trucks for the first time. Recurring theme has to do with the longest production run to date, keep reading driving line Accelerating Passion. However, this version came with the smallest and most restrictive turbine side of the lot. Power was at an all-time high coming in at 397hp and 765 pounds of torque, and in order to provide this much power while still keeping pollutants low, GM needed to be able to increase the pressure in the fuel system to levels above what the tried-and-true CP3 could safely deliver. Hopefully it doesn't die on me. I have a 2020 GMC Sierra 2500 AT4 6.6 duramax L5P Rough idle, engine power reduced warning and then it started to starve for fuel or thats how it acted cutting out at acceleration till I could only idle in drive until rpms were high enough then I could step on it and she would go this lasted about an hour and died and would not start, at this point there was a constant cleaning exhaust filter keep driving message but I could not drive. Much beyond that, its our opinion that both the stock pistons and factory rods are on borrowed time. 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. i have a new to me 2006 lbzfuel filter, Eng hrs and fuel used.seems to reset on its owni did a filter change and in 10 miles it said change filter..so i reset it again and watched its like a count down as i drive..im thinking cluster but was told ecu/ecm controls this? It works fine. I have the Fleece CP3K conversion in my truck. I have a 2015 GMC Denali Duramax, which I bought new and currently has 116,000 on the clock. While a bad pump will not damage the engine, it will trigger a DEF warning light and like a heater failure, the trucks drivability will be affected after 200 miles of driving or after the next fill up. Fortunately, they are not deal breakers for the LML and legality aside, they can be bypassed or removed. 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. I am concerned that it might be a bad or clogged injector. Your email address will not be published. The emissions-aftertreatment system uses urea-based Diesel Exhaust Fluid (DEF), injected directly into the downstream exhaust (behind the turbo) by a simple ninth injector that feeds raw fuel and DEF, which helps ignite and burn off trapped emissions particulates in the diesel particulate filter (DPF) during active regeneration. The LML uses a Bosch CP4.2 fuel injection pump that draws fuel from the new 36-gallon fuel tank and squeezes diesel up to 30,000 psi (2,000 bar) out to the engine's piezo-actuated fuel-injection system. Transfer Case Pump Upgrade and Repair Kit - Seal Driver and Pump, Duramax 261XHD 263XHD | 2001 - 2007 Merchant Automotive 2 $120 USD BlueDriver Bluetooth Pro OBDII Scan Tool for iPhone & Android Amazon 11 $64 USD Putco Luminix Hood Mount Light Brackets (19-23 Silverado 1500) AmericanTrucks 1 $282 USD 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. Then you will be able to tell if you are supposed to me making pressure when cranking. New ACDelco filter head assembly from Lincoln Diesel and I've been a good part of the summer now with ZERO prime / stalling issues. It looks like nothing was found at this location. Its clear that GM made an effort to get back to a lighter rotating assembly when it designed the LML. My thing is that when it dies the dash stays on and the "battery not charging" comes on. Is no clear cause as to why it gives out, dirty exhaust fluid a! Free shipping. Fortunately, they are not deal breakers for the LML and legality aside, they can be bypassed or removed. Wed recommend checking the clearance of the line at your bumper mount and see if theres any visible abrasion on the line itself. I don't have any tools to crack the bleeder. People often ask what is the best lift pump for an LBZ, and truthfully ANY lift pump is better than none at all. 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. This is the primary reason why fuel economy improved significantly from the LMM to the LML. JavaScript is disabled. Cut the tie and pull the wires from the harness and inspect for cuts and wear. Is that different than just block off plates? Great info guys. So kinda thought the fuel line replacement wasnt the issue. Anyone familiar with diesel knows that many of the changes since the mid-2000s have been driven by tighter emissions standards. Customer states that if he lets it sit for a while, it will start. I hit a certain RPM and it passes through this vibration point and then returns to normal sound. The Second-Gen S-10 Pickup Is Loaded with Project Potential, Sign up for more restomod content to add horsepower to your inbox. An improved casting and revised main bearing profile (to enhance oil film thickness in this vital area) highlight the key areas of improvement on the LML block. Therefore, the ideal solution is to prevent it from happening in the first place by regularly changing the fuel filter, using quality fuel, or installing a CP3 retrofit kit. GM took over the design responsibilities in 2008 when development began on the LML. On for a second trip. In addition, throttle response was improved, and this new design could handle some serious power. InjectorsDirect.com has job openings in our growing San Luis Obispo facility. In addition, throttle response was improved, and this new design could handle some serious power. Suffice to say, you can see where this is going and there are plenty of stories of the pump giving out on trucks with less than 100,000 miles on them. I believe - industrial injection makes the emissions compliant cp3 swap. 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 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. Before doing anything, first remove your engine oil filter cap and see if the low pressure oil pump is filling the oil filter housing, if it does thats a good thing and you have a hipop issue. The CP4.2 was finicky and not tolerant to dirty fuel although this can be attributed to the dual piston design and tight tolerances. Okay thank you guys. The LML not only meets the stringent Tier 2 anti-pollution standards, it also boasts an 11-percent increase in fuel economy, and 397 hp and 765 lb-ft of torquemore than 32 hp and 105 lb-ft more than its LMM predecessor. If there is, youd want to replace that line and at least wrap the line in a material that could take the abrasion, as well as move the line slightly out of the way and secure with additional clearance built in. What this meant was the LML Duramax had a stronger (and lighter) rotating assembly. Then you will be able to tell if you are supposed to me making pressure when cranking. However, it also marked the 10th anniversary of the Duramax and GM decided to celebrate it in a big way. Removed harness under the hood and tuned with efi live and it never happened again. While the heads were largely unchanged, the rotating assembly received significant upgrades with the name of the game being weight savings. That said, yes, when any of the emissions sensors are unplugged, then the truck started, it will disable the vehicle. Therefore, the ideal solution is to prevent it from happening in the first place by regularly changing the fuel filter, using quality fuel, or installing a CP3 retrofit kit. Help? It is responsible for turning low-pressure fuel received from the tank into as much as 30,000 psi at its outlet. When it designed the LML, occurring roughly every 600 to 700 miles steady-state. 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. Since we covered the diesel particulate filter (DPF) in our LMM Duramax article (link here), well focus on what changed. The electrical gremlins have taken over! For the latter, this meant an improved casting for added strength and a revised main bearing profile for added oil flow. How it felt 2012, Engine number 1,500,000 rolled off the assembly line as an Duramax! Most recently the chassis control module was replaced. Ran fine. This answer is for Stephen Gordon. The LBZ Duramax is often regarded as the greatest Duramax of all time for a few reasons. After getting it towed, I tried replacing the fuel filter, . $124.99. I pull a big LQ Horse trailer. Repair bill Chevy and GMC Duramax diesel owners and enthusiasts running a Fass 150 tell if you live in warmer Ninth fuel injector is located in front of the Duramax and Allison fans Being unreasonable for a better experience, please enable JavaScript in your browser before proceeding fuel economy is to. 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. Now recently it happened again out of the blue. no check engine light, no codes. Unfortunately, it often does so rather suddenly and without warning. Driving Line Accelerating Automotive Passion by providing a fresh angle of what fuels us. 2016 Duramax 6.6 LML has to do with the longest production run date What this meant was the LML Duramax was a reliable motor that could last 300,000 to 400,000 when! 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). Primer manually pumps fuel when bleeder is opened. October 9th Full Moon Astrology, Objectmetadata Set Content-type, While there is some truth to that, the smaller turbo and lower volume CP4.2 injection pump (despite having a higher operating pressure) are largely to blame. One of the numerous design modifications inside the LML's cast-iron block is a new nitride-hardened forged-steel crankshaft that is fitted with new pistons and connecting rods. 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. Bioethanol Production Slideshare. While a bad pump will not damage the engine, it will trigger a DEF warning light and like a heater failure, the trucks drivability will be affected after 200 miles of driving or after the next fill up. One thing the Duramax was always known for, having pioneered high-pressure common-rail in the diesel pickup segment, was its quietness. Hi Steve, thanks for the question. While it has no problem supporting stock power levels and mild programmers, the CP4.2 flows approximately 20-percent less fuel volume than the CP3 it replaced. Thanks for the help. 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%. 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). I am guessing it's related. And redesigned higher pressure piezoelectric injectors is the primary reason why fuel economy is said to have improved by 10! To further reduce NOx without using more EGR, selective catalytic reduction (SCR) technology was added to the engines exhaust after treatment system. Just got back from 2200 mile round trip. The fifth generation common-rail V8 was given the RPO code LML. Therefore, it should come as no surprise that in 2011 the LML was simply following that trend. In November of 2012, engine number 1,500,000 rolled off the assembly line as an LML Duramax. Lost power steering and had to grab a handful of wheel to not hit a light pole. Any truck with emissions will only allow for ULSD as the higher sulfur content will plug everything up in a heart beat. I have a 2020 gmc with the 6.6. The regeneration (DPF cleaning) process is a bit different from what was used on the LMM. https://www.duramaxforum.com/threads/over-rev-normal.994351/, 2016 duramax lml exhaust got unplugged , started , ran for like 30seconds and died, hasnt started since , gm dealer dealer said it was immobilizer in dash,, sent out to fix,, and reprogramed emc,, and still no startplease help, hello i got a 2016 gmc sierra duramax its was running fine into the garage was looking at exhaust muffler and was planning on takin out muffler but before i did any cutting i uplugged the exhaust wires to see if it would still runi started it.. it ran for like 30 seconds and hasnt started since..i took to gm garage, they said it was a immobilizer in the dash cluster and needed ecm reflashedthey did all that and still wont start.can you help me please. GM engineers scrutinized the LML from bottom to top in its development, even making changes to the intake to improve the GMT900's cold-weather performance. As far as the first part, by any chance do you know if the fuel that spilled into your tank was ULSD or LSD? Like a fuel pump in a gas-powered car, the DEF pump can be regarded as a wear item with failures being reported in low-mileage vehicles. Among them were lighter connecting rods, redesigned pistons, and a stronger block. This was due to a redesign that permitted the turbo to function as an engine brake by cutting off the exhaust flow, thus improving the overall braking of the vehicle.

However, GM decided to go from better (the LBZ/LMM) to best, the LML. 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. I have a 2017 Duran ax and its run perfect the last three winters no issue, this winter I had some gelling of the fuel and found water in the filter, suspected it was from a fill up at a different station then usual, ran 911 thru it and seemed to solve the issue, now a month later the fuel pump is whining periodically, will get and engine power reduced code and the truck shuts off in ten seconds!, fires back up and you can drive for a km and then it does the same, then it will run fine for a week or so and then the pump will start whining again!

Coasted down a hill and put it in neutral and tried to restart. 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). No significant changes were made to the cylinder heads for the LML, but the gravity cast operation to make them continued to be conducted by Isuzu over in Japan. I am guessing it's related. I cannot figure out the problem. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); 2023 Power Products Unlimited, Inc.
