What is a diesel FCA?

Basically, the FCA is the metering device for the CP3 injection pump. Presuming the truck starts, immediately turn it off as you will have full pressure running to the fuel rail, but at least you have fairly high certainty that the FCA was causing the issue.

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.

Is the ECM the same as the fuel control actuator?

“The Fuel Control Actuator (FCA) 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.”. You are correct, it’s not the same as the fuel pressure limiting valve..

How to test a Cummins fuel control actuator?

1. FUEL PUMP 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. Observe the test light.

How to measure resistance of fuel control actuator?

Measure the resistance of the (K65) return circuit between the FCA harness connector and the ECM harness connector. Is the resistance less than 10 Ohms? Repair or replace the engine wiring harness. Perform POWERTRAIN VERIFICATION TEST (DIESEL). (Refer to 9 – ENGINE – STANDARD PROCEDURE) 4.

What is voltage of fuel control actuator k604?

(K604) FUEL CONTROL ACTUATOR DRIVER CIRCUIT SHORTED TO EXTERNAL VOLTAGE Measure the voltage between the (K604) FCA driver circuit in the FCA harness connector and battery negative. Is the voltage greater than 1 volts? Repair the (K604) FCA driver circuit shorted to external voltage.
