If you’re experiencing issues with your fuel pump, it may be because of a faulty module. The fuel pump driver module is a crucial component in the fuel pump circuit that regulates the power supply to the fuel pump.
It’s responsible for ensuring the fuel pump operates at the correct voltage and the fuel pressure throughout. It communicates with the engine control module to maintain optimum fuel pressure levels. If you’re not familiar with the location of the fuel pump module, you may wonder where to look.
The fuel pump control module location is near the rear of the fuel tank or mounted on the frame rail, and its exact location may vary depending on the make and model of your vehicle. In our guide, you can learn more about the ins and outs of fuel pump control modules, including their function, common symptoms of failure, maintenance, and where they are typically located.
By the end, you will stand a better chance of knowing the Ford E250 fuel pump driver module location. (Read Why Is My Floorboard Wet Drivers Side)
What Is a Fuel Pump Control Module?
Before diving into the location of the fuel pump control module, let’s briefly review what this component does. The fuel pump driver module function or the pump control module location is replaced by a small computer that controls the fuel pump circuit in your vehicle.
It receives signals from various engine and fuel system sensors and uses that information to control the fuel pump’s performance.
Symptoms of a Faulty Fuel Pump Control Module
So, how can you tell if your truck, fuel tank, or pump control module is faulty? There are several symptoms to look out for, including:
- Engine won’t start: If your car or fuel pump control module fails, it may prevent the engine from creating.
- Engine stalls: A faulty fuel pump module can also cause the engine to stall or shut off unexpectedly while driving.
- Fuel pump runs continuously: In some cases, a faulty control module may cause the fuel pump to run continuously, even when the engine is turned off.
- Decreased power and fuel efficiency: If the Ford module part is not working correctly, it may cause the engine to use more fuel than usual.
- Check engine light: Finally, a faulty module can cause the truck side check engine light to turn on.
If you’re experiencing any of these symptoms, having your vehicle checked by a mechanic as soon as possible is essential.
Where Is the Fuel Pump Control Module Located?
Now, let’s get to the core: where is your fuel pump control module located?
The answer to this question can vary depending on the make and model of your vehicle. However, in most cases, the answer is the fuel pump control module is near the passenger side fuel or gas tank.
To find the Ford fuel pump control module in your vehicle, you may need to consult a page in your owner’s manual or a wiring diagram.
Some common locations for the fuel pump control module include:
- In the tank: In some vehicles, the fuel pump control module is located inside the fuel tank and the fuel pump itself.
- On the passenger side frame rail: Another common location for the fuel pump control module is on the rear of the frame rail near the fuel tank.
- Under the rear seat: The fuel pump control module may be under the driver-side rear seat in some vehicles. It can also be behind the right-hand side rear seat.
- In the engine compartment: Finally, some vehicles may have the fuel pump control module on the right side of the engine compartment, near the location of the battery or fuse box.
If none of these locations contain your module, chances are you have an older vehicle model, and it may be found beneath the spare tire. It will most often be if the spare tire is in the trunk. Remove this, and you may see a panel.
Remove this, and you should see the control module. Just remember to replace your spare tire once finished. If your control module is exposed, such as outside your gas tank or inside the Ford engine compartment, it may need maintenance more often as contacts can easily suffer from corrosion.
Do You Have A Low or High-Pressure Fuel System?
Do not check the Fuel Pressure from the High-Pressure Fuel Pump if your vehicle has a low-pressure and high-pressure fuel system, even if you have the same problem. It can cause significant injury and is classified at 2175 PSI. To validate the Actual and Requested Fuel Pressure on the High-Pressure side, it is advised to head to your Ford dealer and has the programmed circuit tested by them using their scan tool.

How to Test the Fuel Pump Control Module?
After locating the fuel pump control module, the next step is to test it. Here are the steps to follow:
- Check the voltage at the fuel pump input relay to ensure that the fuel filter relay is getting enough power to operate.
- Use a digital multimeter to test the resistance of the fuel pump control module. You should be able to measure the resistance across the two pins of the fuel pump control module. The fuel pump module is faulty if the resistance is too high or too low.
- Check the wiring diagram to verify that the wiring is correct. If there are any wiring problems, you will need to fix them before proceeding.
- Use a scan tool program to check for any trouble codes related to the fuel pump control module. If you find any codes, you must address them before testing the whole engine control module again.
If all the above steps are successful, you can test the fuel pump control module. To do this, connect a test light to the positive battery terminal and touch the test light to the fuel pump control module’s ground wire. The test light should light up, indicating that the fuel pump control module location is functioning correctly. (Learn How Long Does It Take To Replace A Fuel Injector)
How to Replace a Faulty Fuel Pump Control Module?
If your tests confirm that the fuel pump control module is faulty, you must replace it. Here’s how to do it:
- Disconnect the battery’s negative cable.
- Disconnect the wiring harness from the fuel pump ignition control module.
- Remove the screws holding the module and remove the module from the vehicle.
- Install the new fuel pump control module in the reverse order of the removal process.
- Reconnect the wiring harness to the new module.
- Reconnect the battery’s negative cable.
The fuel pump control module plays a crucial role in the operation of the fuel pump. If you experience problems with the fuel pump circuit or its performance, it could be because of a faulty fuel pump control module.
By understanding the symptoms of a faulty fuel pump control module and its location, you can diagnose the problem and replace it if necessary.
In summary, if you’re experiencing truck fuel pump issues, check the truck fuel pump driver module control module’s functionality and fuel pressure. It’s a small but vital component that can cause significant problems if it fails. (Read Fuel Additive To Remove Water)
Remember to use a scan tool and test light when diagnosing and replacing the fuel pump driver module. If you’re uncomfortable working with the fuel pump control module, it’s best to seek the help of a qualified mechanic to avoid any further damage or injury.
