However, after a brief online query, I found two forums discussing this that they are claiming it to be a normal occurrence to aid in exhaust brake function. Quality low fuel injection. Hi Steve, thanks for the question. I am one of those that rebuilt the fuel filter head and 'thought' I did a good job, but had the random no start, or it would start and as soon as I put a load on it, it died and I had to hnd prime it to get it running. dont see any smoke out tailpipe. All told, there are six different iterations of the Duramax diesel engine: LB7, LLY, LBZ, LMM, LML, and L5P spanning from 2001 to the present day. Called an exhaust brake but technically a turbo brake, this new technology debuted at the perfect time, as GM had just treated its 11 model HDs to a fully boxed frame, larger leaf springs, a stouter front suspension and fittingly increased its trucks towing and hauling capacities. I just had the CP4 Fuel Pump changed to a CP3. Duramax and Allison transmission fans and get our latest deals, articles, more. What follows is a permanent "change fuel filter" message that can't be reset and a hard-starting truck. The LML was the first Duramax to get this system. 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). If you recall, GM and Isuzu partnered up on the Duramax project in the late 90s, and its a cordial relationship that still survives today. The trucks computer keeps track of how much fuel needs to be added or subtracted from each individual cylinder to make the engine run smoothly, and this value is called the balance rate. Directly supporting the piezoelectric injectors is the Bosch CP4.2 injection pump. If one cylinder is contributing too much or not as much as the rest, the cause is usually a bad injector and the cure is a replacement. 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.
