2007.5 to 2018 Dodge Ram Commonrail 6.7L Cummins FCA Fuel Control Actuator Sensor
The Dodge Ram trucks from 2007.5 to 2018 with the 6.7L Cummins diesel have an all too common problem of the fuel control actuator failing. The Cummins 4936097 FCA is an electronic metering device for the flow of fuel to the CP3 injection pump.
The 4936097 6.7L Electronic Fuel Control Actuator FCAapplications:
- All 2007.5 to 2018 Dodge Ram 2500 series trucks.
- All 2007.5 to 2018 Dodge Ram 3500 series trucks.
- All 2007.5 to 2018 Dodge Ram 4500 series trucks.
- All 2007.5 to 2018 Dodge Ram 5500 series trucks.
If the Cummins 4936097 FCA is not correctly functioning, the Engine Control Module / ECM cannot determine the fuel flow rate supplied to the CP3 Fuel injection Pump. In most cases, people first know there is an issue when they have a hard start or no start issue because the FCA will not allow the pump to build pressure to start correctly. However, by the time this occurs, the truck has probably been delivering less than the required amount of fueling for a while already as the FCA is a simple spring design that many times takes a rather slow death and not an immediate failure. The Engine Control Module / ECM uses the fuel control actuator to control the fuel pressure in the 6.7L common rail Dodge Ram diesel. The Fuel Control Actuator is an electronically controlled solenoid valve that is constructed with corrosion-resistant external housing for increased component durability.
The ECM controls the amount of fuel that enters the high-pressure pumping chambers by opening and closing the FCA based on demand. The fuel control actuator also controls the return of fuel back to the diesel fuel tank.
What are the symptoms of a failing 6.7L Cummins Fuel Control Actuator?
A faulty 6.7L Cummins fuel pressure regulator causes these symptoms. Replacing your 6.7L Cummins regulator can resolve your problem and get you back on the road.
If you're experiencing hard start or no start issues, one easy way to confirm whether or not the FCA is causing the problem is to unplug it, thus eliminating any metering simply. Presuming the truck starts, immediately turn it off as you will have full pressure running to the fuel rail, but at least you have reasonably high certainty that the FCA was causing the issue.
