P2A1CInjection Pump Fuel Metering Control E Low (Cam/Rotor/Injector)

P2A1C indicates that the engine control module (ECM) has detected an abnormally low electrical signal from the fuel metering control circuit of the injection pump, specifically the circuit associated with the cam, rotor, or injector. This low signal prevents the ECM from accurately commanding fuel delivery, which can lead to poor running or a no-start condition.
