The remanufacturing business supplies fully reconditioned products for engine remanufacturing and field service needs. The spec. Among other differences, the most significant was the change to the High Pressure Common Rail (HPCR) fuel system. If fuel pressure drop is within specifications, the fuel pump outlet check valve and the fuel pressure regulator are both operating normally. The low pressure fuel pump draws fuel from the fuel tank through the 10 micron primary fuel filter and pushes it to the engine mounted fuel filter. The weight of fuel also helps add pressure to push liquid through your pump, and without this pressure, your pump has to work harder, shortening its lifespan. I am going to check the pressure then change the fuel filter, then check the pressure. Low fuel pressure (weak pump, restricted fuel line, low voltage to the pump or a defective fuel pressure regulator) If the pump runs and generates normal pressure to the engine, but the engine still does not start, the problem may be: 1.
