Quick Answer

Quick Answer What is FCA on Cummins?

The Cummins 4932457 FCA is a metering device that determines the flow of fuel to the CP3 fuel injection pump. The Cummins 4932457 Fuel Control Actuator determines the rate of fuel pressure provided by the fuel injection pump for proper engine operation.

How do I know if my Cummins is 5.9 FCA?

Dodge Ram 5.9 Cummins diesel FCA (fuel control actuator) replacement

Where is the fuel control actuator located on a 5.9 Cummins?

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.

What is an FCA on CP3 pump?

5.9 Cummins FCA Replacement Video

What causes low fuel rail pressure Cummins?

Most starting problems due to low pressure are caused by bad (eroded check ball seat) injectors. You can unplug the fuel control actuator and the pressure should default to maximum (26,107 PSI), however if there is a leak in the injection system then the pump will not build enough pressure.

How do I know if my CP3 pump is bad?

This is a one-stop symptom checker for issues related to common rail injectors and CP3 pumps.

  1. High-Pressure Common Rail Basic Information and Function.
  2. Do You Have No Start Or a Hard Start?
  3. Do You See Black Smoke?
  4. Can you hear Knocks?
  5. Do You Have Slow Deceleration?
  6. Is there Blue/White Smoke at Idle When Cold?

What should fuel rail pressure be 5.9 Cummins?

Your idle pressure should be around 7k , and max at WOT should be 25k’ish .

What is a fuel control actuator?

Basically, the fuel control actuator is the metering device for the CP3 injection pump. If the FCA is not working properly, the ECM cannot communicate to the pump how much fuel it should be delivering.

What is FCA on 6.7 Cummins?

The Cummins 4936097 FCA is an electronic metering device for the flow of fuel to the CP3 injection pump.

Where is fuel rail pressure sensor?

A fuel rail pressure sensor (commonly known as a fuel pressure sensor) is used in many diesel and some gasoline engines. This sensor is usually located near the middle of the fuel rail and is linked to the engine control unit (ECU), which is the central computer of a vehicle.

Where is the fuel control actuator 6.7 Cummins?

OEM fuel control actuator for ‘07.5-’18 Dodge Turbo Diesel trucks equipped with the 6.7L engine. Located on the side of the high pressure fuel injection pump, the electronic fuel control actuator is the metering valve of the fuel system.

How does CP3 FCA work?

What is a cp3 and how does it work

How long does a CP3 pump last?

The Bosch CP3, used on the ’01-to-’10 Duramax and ’03-to-current Cummins engines, is known to last 250,000 miles or more before needing to be replaced. Of course, performance enthusiasts also know these pumps are only capable of supporting approximately 500 hp.

How much fuel pressure does a CP3 need?

If you are running a CP3 in a high-performance application, we highly recommend installing a fuel supply pressure gauge to ensure there is correct fuel pressure at all times. Recommended feed pressures for CP3 and CP4 equipped engines: Dodge/Cummins ’03 – ’16 (5.9L &amp
6.7L) no less than 8 PSI / no more than 15 PSI.

How do you fix code P0087?

What repairs can fix the P0087 code?

  1. Replacing the fuel filter or screen.
  2. Replacing kinked fuel lines.
  3. Removing and replacing the fuel pump.
  4. Replacing a faulty fuel pressure sensor.

What should common rail fuel pressure be?

Common rail direct fuel injection is a direct fuel injection system for petrol and diesel engines. On diesel engines, it features a high-pressure (2,000 BAR – 29,000 PSI) fuel rail feeding individual solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors or pump nozzles.

How do you check the fuel pressure on a 5.9 Cummins?

The fuel-pressure gauge can be screwed directly onto this port for testing.

  1. Pop the hood on the Dodge Ram and locate the test port on the left-hand front side of the engine compartment.
  2. Unscrew the valve cap and pull it back out of the way.
  3. Start the Dodge Ram and allow it to run for around five minutes.

How do I know if my 5.9 Cummins has a bad injector?

How can you tell when a 5.9 Cummins injector pump replacement is imminent? Some symptoms of 5.9 Cummins injector pump problems include lack of power, not starting, or hard starting. Bad injectors can also cause a knock in the engine.

Does a CP3 pump need to be timed?

The CP3 isn’t timed. It has about the same operating principle as your power steering pump.

What should my fuel pressure be in 24v Cummins?

The FSM states that fuel pressure should be 10psi at idle, no other specification. That said the experienced members state that 10 psi should be the minimum at WOT, and I agree.

How much fuel pressure does a 12 valve Cummins have?

For a 12 valve the gauge must be at least 40 psi, 60 psi is best. The gauge can say boost, air, water, fuel or nothing on it, they will all work excellent.

How much fuel pressure should a 24v Cummins have?

cummins spec is the vp44 must have no less than 10psi any time the motor is running, and 7psi while cranking.

Is a fuel pressure regulator a actuator?

WHAT DOES A FCA DO? The Fuel Control Actuator is located at the rear of the high-pressure, fuel injection pump (Fig. 13).

How does a fuel actuator work?

The actuator is controlled either by a mechanical governor or an ECU / ECM. When you apply load to a diesel engine, the actuator reacts by allowing more fuel into the engine, to try to maintain its speed. When you remove load, the actuator restricts the fuel, again to maintain the speed.

What fuel pump does the 6.7 Cummins have?

The factory fuel system on your 6.7L Dodge Cummins consists of your underbed fuel tank, fuel or lift pump, high pressure CP4. 2 injection pump featuring a twin piston pump that can handle up to 39,000psi, and electronically controlled injectors (simplistically put).
