It has been suggested I change out the fuel solenoid at the pump.


Help???

Check the fuel pressure going to the injection pump and then the pressure going back to the tank. Possibilities are, pump regulator control or injector pump fuel valve feedback. Chrysler training video. Chrysler Master Tech videos

If anyone needs a laugh watch the old videos Like this one LMAO/ROTF

P0251 - CP3 Pump Regulator Control; Injector Pump Fuel Valve Feedback: The ECM detects a discrepancy between PWM supplied to FCA and PWM returned from FCA.
Possible causes:
- Intermittent condition
- Fuel Control Actuator
- Return wire open from FCA to ECM
- Supply wire open from FCA to ECM
- Supply circuit shorted to voltage
- ECM
Also check the 15/16 nuts on your injector tubes, sometimes they're loose and will throw that code.
