Order of inspection
P0254 Injection Pump Fuel Metering Control A High (Cam/Rotor/Injector) High
The P0254 code means there is a fault in the control of the amount of fuel the diesel injection pump (A) delivers, with the circuit voltage higher than expected. It usually causes a loss of power, hard starting or an engine that stalls. Check for an open circuit or a short to voltage first.
