Engineering Machinery Fault and Detailed Solution:

Equipment: Cummins-Powered Kenworth T880 Truck with ISX Engine.
           Fault: The engine intermittently loses power and has a noticeable hesitation under acceleration; diagnostic code points to low fuel rail pressure.
           Analysis & Solution: Intermittent power loss and low fuel rail pressure on a high-pressure common rail system (like the ISX) often trace back to a failing Fuel Pump or a leaking Injector (excessive return flow). The most common cause is a restriction in the fuel supply, such as a clogged Fuel Filter, or a worn-out High-Pressure Fuel Pump (HPFP). The solution involves replacing the fuel filters first. If the problem persists, perform a leak-off test on the injectors to check for excessive fuel return. If the injectors are good, the HPFP may not be maintaining pressure. We recommend sourcing a new HPFP or an Injector Set from a reliable supplier to ensure the precision required by the ISX platform.
