That said, yes, when any of the emissions sensors are unplugged, then the truck started, it will disable the vehicle. The LBZ injector nozzle has seven holes for fuel to spray out of, but the LMM has six which means there are two opposed streams of fuel directly above the wrist pin area of the piston, which causes hot spots directly on top of the weakest area which can lead to cracking. 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. Coasted down a hill and put it in neutral and tried to restart. Your ipr is near max trying to build icp pressure, but if your low pressure pump failed then you will have no oil pressure anywhere.

Customer states that if he lets it sit for a while, it will start. JavaScript is disabled. 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 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.
