A “fuel pump control module” is a device that controls the amount of voltage delivered to the vehicle’s fuel pump. Controlled voltage is necessary to maintain optimum fuel delivery and pressure in the fuel pump. Smooth and efficient working of the fuel pump control module is essential so that your car may not halt. It ensures the optimum working of your vehicle.
The “fuel pump control module” location varies from vehicle to vehicle. In the older cars, it was installed near the fuel pump. But, this installation setup led to overheating problems. Now, the module is installed under the seat or on the vehicle's floor covered by a carpet.
The proper calibration software is required for the appropriate programming of the fuel pump control module. The module uses and stores the software information to control the fuel pressure. Configuring the module with the wrong calibration software doesn’t enable it to control all vehicle features properly. The battery of the fuel pump module should be fully charged before programming. Make sure to load the scan tool with the latest software version. If the module doesn’t respond to the program, verify the module's connections again.
The ‘fuel pump control module’ enhances the efficient working of the vehicle. It provides the following benefits to the engine and the car:
Uncontrolled fuel pressure can lead to high consumption of fuel. The fuel pump module controls the amount and pressure of the fuel pump to the engine. Hence, it improves fuel economy and provides the necessary voltage to maintain fuel pressure.
The fuel pump control module can be used with any variety of fuel pumps, such as:
The fuel pump module helps your vehicle to start quickly. The car will not take long to start and will help you reach your destination quickly.
Turbulent fuel can decrease the efficiency of your engine. That’s why a fuel pump control module is required to enhance the efficiency of your engine. It decreases the resistance offered to the engine by the fuel. It also increases the life of the engine and makes it last longer.
Installation of fuel pump module provides overall good acceleration to your vehicle. It maintains the speed of the car and prevents jolts and halts. It also reduces the loss of boosts during the turns.
It gives a quiet startup to the car by reducing the amount of noise made by the engine. Hence, a fuel pump control module increases the overall efficiency of your vehicle.
Yes, you can drive a car with a bad fuel pump control module, but not permanently. After a while, your vehicle will start showing the symptoms of a bad fuel pump module. Sudden stalls and halts of the vehicle will make it challenging to drive your car efficiently.
Some car engines are really sensitive to changes in fuel pressure. If you feel poor working of your fuel pump module, take your car to the mechanic immediately. For more, please refer to Can I drive with a bad fuel pump
If the faulty fuel pump is not changed, it can destroy your engine's working. A faulty fuel pump module does not provide enough pressure to the fuel pump. Decreased fuel supply to the fuel pump will result in overheating of the engine. Contamination of fuel also leads to wearing out of the engine. Dust particles, moisture, foul gas, and rust can clog the fuel strainer and decrease the fuel pressure.
A fuel pump control module is installed on the floor of the vehicle. So, it is vulnerable to road debris and other chemical compounds, which may lead to module corrosion. Corrosion damages the electronic circuits of the module and produces “whirring sounds” in the regulator. The sound is especially noticeable when the car accelerates or climbs a hill.
If you observe any of the following signs in your car, there is a possibility that your module is faulty. However, they can also be because of any other car problem. So, a proper diagnosis is needed by an expert mechanic.

If you continuously feel difficulty starting your engine, then probably your fuel pump module is why. Decreased fuel pressure in the engine will make it difficult to start.
A faulty fuel pump module decreases the efficiency of both fuel and the engine. It creates the problems like surging, misfiring, and lack of power.
Usually, the engine makes slow humming sounds. But when it produces loud whirring sounds, there is something wrong with the fuel pump module.
Smoke rising from the engine is another indication of a faulty fuel pump control module. If you observe a large amount of smoke from the engine and the burning smell, immediately call a mechanic.
Decreased engine efficiency due to faulty modules will automatically lead to overheating of the fuel pump. This can be dangerous if not treated immediately.
You may experience sudden jerks and jolts during driving due to a bad fuel pump control module. The acceleration of the car is also reduced, which decreases car efficiency.
A handheld scanner is used to detect faults in the fuel pump control module. Mechanics use this to diagnose the error code. A multimeter can also be used to test the fuel pump control module. The reading of the meter should be within one volt.
If your car gets into an accident, then there are chances that you may need to restart your pump module. Your dashboard will warn you to restart your fuel pump control module. You just have to follow the following simple steps to restart it:
The cost of replacing the “fuel pump control module” depends upon the type of vehicle and engine. The average cost to replace a fuel pump module ranges from 220 dollars to 1100 dollars. This is an estimated cost and does not include taxes and fees. It takes almost 2 to 3 hours to replace a fuel pump control module. It is a pretty challenging process. So you should take your car to the mechanic to replace the module.

If you are looking for a new fuel pump control module, you should do little internet surfing before buying it. It is essential to purchase the product from a reliable automobile company for the best results. A good fuel pump module manufacturer provides you with the following benefits.
The fuel pump control module can get corroded by rust substance, moisture, and dust from the road. A good manufacturer provides corrosion-resistant fuel pump modules. They manufacture products that offer high tensile strength and durability.
Good manufacturers also provide a handout containing all the instructions to assemble a fuel pump control module. The assembly consists of parts like a fuel pressure regulator, screen filter, no return valve, sender unit, etc.
A reputable automobile company offers shipping services all across the globe. They have branches all around the world to fulfill the demands of people. They also provide a guarantee and return policy for their products.
You should never compromise on good customer service. It’s important to check if manufacturers respond to their customers, solve their problems, and satisfy their queries.
Overheating is a common issue for various fuel pump control modules. But good manufacturers provide modules that work efficiently at elevated temperatures and ensure the safety of your vehicle. Vehicles with modified engines, such as sports cars, require special fuel pump modules for their work to prevent overheating.
Check the customer reviews before buying the product from any company. Or you may ask for suggestions from family and friends. If the customers are satisfied with the quality of the products, you can buy them too.
