What is a fuel actuator?
What is a fuel actuator?
The Fuel Control Actuator (FCA) or Fuel Pressure Regulator is an electronically controlled solenoid valve. The ECM controls the amount of fuel that enters the high-pressure pumping chambers by opening and closing the FCA based on a demanded fuel pressure.
Where is the fuel control actuator on a Cummins truck?
Located on the side of the high pressure fuel injection pump, the electronic fuel control actuator meters the amount of fuel flow to the high pressure fuel pumping chambers in the high pressure fuel pump. NOTE: This is an electrical part and if it has been installed on your truck it is non-returnable.
What to do if fuel control actuator is not working?
Ignition on, engine not running. Disconnect the Fuel Control Actuator (FCA) harness connector. Connect an incandescent test light across the Fuel Control Actuator driver circuit and the Fuel Control Actuator return circuit at the fuel control actuator harness connector.
How does the ECM work on a fuel control actuator?
The ECM detects a discrepancy between the PWM supplied to the Electronic Fuel Control Actuator and the PWM returned from the Electronic Fuel Control Actuator. Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.
How often does Cummins fuel rail pressure Hiccup?
Good price on the product and the replacement screws included were very convenient. 2004 Cummins. Fuel rail pressure was surging roughly 1000psi from desired pressure. Truck also ran with a hiccup every 5 or so seconds when rail pressure would surge 3000 psi.

What are the symptoms of a failing Cummins fuel control actuator-FCA-KLM?
What are the symptoms of a failing 5.9L Cummins Fuel Control Actuator – FCA? A Rattling Noise from the engine, which sounds like Fuel Knock. You have decreased the engine power output level. Engine operation is rough. A faulty fuel pressure regulator causes these symptoms. Replacing your 5.9L Cummins regulator can resolve your problem.
