Fuel Rail Pressure Too High Dd15 at Nate Catt blog

Fuel Rail Pressure Too High Dd15. Recently we found that the water separation unit was empty and adding fuel then priming got the truck to start and drive but only a few miles till it shuts down again. Internal or external leakage of the high pressure fuel system (too high, leak down test) the motor control module (mcm) monitors rail pressure. When rail pressure deviation is greater than 200 bar while under a load this code. Charts were looked at after test drive by dealer and it matches what is their normal. Use dddl to check for stored or active codes and repair if necessary. The fault condition is typically related to an internal or external leakage of the high pressure fuel system (too high, leak down test). Install a clear hose or site glass in line between the fuel tank and fuel pump on the supply side but also on the return. Check fuel level and correct if necessary. ⚠️⚠️⚠️always use the proper tools and safety equipment to perform this job. Most commonly would be a problem with either fuel supply or injectors.
