Meet the fuel pump control module, the small yet mighty component that keeps your vehicle running smoothly. However, where is the fuel pump control module located?
In most cases, you’ll find it mounted on or near the fuel pump assembly or within the engine control module (ECM) housing. That said, its precise position can vary from one vehicle model to another.
There is a lot to be discussed regarding this subject. Please keep reading.
What is a Fuel Pump Control Module?
The Fuel Pump Control Module (FPCM) is a crucial component in your vehicle’s fuel system. Its responsibility is to regulate the operation of the fuel pump. In addition, the fuel pump control module makes sure, that the right amount of fuel is delivered to the engine at the correct pressure, which is essential for optimizing the performance and efficiency of your vehicle.
We would say, the FPCM is the brain behind the fuel pump, as it handles signals from sensors to adjust fuel flow to match your driving habits and driving conditions.
Where is the Fuel Pump Control Module Located?
The Fuel Pump Control Module’s (FPCM) location can vary across different vehicle models. In some cars, particularly older models, you might find the FPCM mounted directly on the frame near the fuel tank, easily accessible for maintenance.
However, in modern vehicles, with more complex fuel systems, the fuel pump control module is located in the Engine Control Module (ECM) or Powertrain Control Module (PCM).
This integration helps wiring and improves efficiency, but it also means that accessing the FPCM for fixing issues can be difficult and it may require specialized tools. As you now know the location of the fuel pump control module, let’s discuss more important details about this invaluable component.
Symptoms of a Faulty Fuel Pump Control Module
Here’s a list of symptoms of a faulty Fuel Pump Control Module (FPCM).
- Difficulty starting the engine: You will experience vehicle starting issues when the fuel pump module control module malfunctions. You may notice prolonged cranking or the engine failing to start altogether.
- Engine stalling or hesitation: As the FPCM maintains consistent fuel delivery to the engine, the engine will stall when it is faulty. This can be especially true during acceleration.
- Unusual engine performance: A malfunctioning FPCM can result in unusual engine behavior, such as jerking while driving. When the fuel supply becomes inconsistent, the engine will display abnormal behaviors.
- Reduced fuel efficiency: As you know an improperly functioning FPCM fails to optimize fuel delivery, which obviously suggests that the fuel efficiency will decrease.
- Warning lights: Fuel pump control module-related issues may cause warning lights on the vehicle’s dashboard, such as the Check Engine Light.
Can I Replace the Fuel Pump Control Module Myself?
Well, replacing the Fuel Pump Control Module (FPCM) yourself is possible, but it can be challenging if you lack a certain level of automotive knowledge. The replacement of the fuel pump control module is often done by the mechanics as it involves removing various engine components and dealing with electrical connections.
In addition, the process requires specialized tools in order to complete a proper installation and calibration. If you don’t possess adequate automotive repair knowledge and have the required tools we recommend you visit a professional for the fuel pump control module replacement.
How Much Does it Cost to Replace the Fuel Pump Control Module?
On average, you can expect to pay anywhere from $200 to $800 for parts and labor to replace the fuel pump control module. However, according to our experience, the prices can be higher for luxury or high-performance vehicles due to the complexity of the FPCM.
In addition, those types of vehicles require a certain degree of expertise for installation. So, it would be best if you obtain quotes from multiple mechanics and compare them for the best solution.
How to Install Fuel Pump Control Module?
Installing a Fuel Pump Control Module (FPCM) involves several steps and we have explained them below for your observation. In addition, you can find a helpful video at the end of this article.
The first step is to park your vehicle on a level surface and turn the engine off. Also, it is important to disconnect the negative terminal of the vehicle’s battery in order to prevent any electrical accidents.
Now locate the duel pump control module as we described earlier. If not, refer to your vehicle’s service manual to find the exact location of the FPCM. As said earlier, it’s typically located near the fuel tank or within the engine compartment.
Now, disconnect the connectors and bolts securing the old FPCM in place and carefully remove the old FPCM from its position.
Now simply, position the new FPCM in place, aligning it with the mounting holes. Secure the FPCM with the mounting bolts and reconnect the connectors.
If you had to remove any components to access the old FPCM, reassemble them in reverse. Now it’s time to reconnect the negative terminal of the vehicle’s battery that you removed in the first place to restore power to the vehicle’s electrical system.
