Fuel pump failure signs: car won't start, stalls, or runs with a lack of power
The fuel pump is one of the most important parts of a car. It pumps fuel from the fuel tank to the engine, which is then burned to create power. The pump also sends fuel to the fuel injectors, which spray it into the engine. If the fuel pump fails, the car will not run.
Signs of a failing fuel pump
A failing fuel pump will not create enough pressure in the fuel system, possibly causing a loss of engine power or preventing the car from starting. Here are some signs that your fuel pump may be failing:
- Car won't start or stalls unexpectedly: A failing fuel pump may cause your car to fail to start or stall unexpectedly. This is because the pump is not providing enough fuel to the engine.
- Engine misfires: Your engine may sputter or misfire frequently, especially during acceleration. This is caused by a lack of fuel and air needed to initiate combustion.
- Sudden surges: Your engine may surge unexpectedly while driving, causing the vehicle to repeatedly pick up and drop speed. This is caused by too much fuel being sent to the engine.
- Poor fuel efficiency: You may notice a significant drop in your car's mileage or fuel efficiency. This is caused by damaged or worn components in the fuel pump, which allow excess fuel into the engine that goes to waste.
- Whining noise: A low-grade whining or whirring noise coming from the fuel tank area, towards the rear of the car, could indicate a failing fuel pump.
Fuel pump replacement cost
The average cost for a Ford Mustang Fuel Pump Replacement is between $1,369 and $1,591 but can vary from car to car. It is recommended that you have your fuel pump replaced by a professional mechanic due to the risk of fire when working with the fuel system.

Fuel pump replacement procedure: disconnect the battery, remove the pump, and install a new one
The fuel pump in a car is responsible for delivering gas from the fuel tank to the fuel injectors. The pump delivers the right amount of fuel and at a high enough pressure to keep the engine running smoothly. The pump can be located inside or outside the fuel tank.
Disconnect the battery
Before starting any work on your fuel pump, it is important to disconnect the battery to reduce the chance of a fire. Disconnect the negative battery cable.
Remove the pump
First, relieve the fuel system pressure. Siphon or drain as much fuel as possible from the fuel tank. If your Mustang has an access panel, you can access the pump without removing the tank. If there is no access panel, you will need to lower the fuel tank to access the pump. Remove any retaining straps or bolts holding the tank in place and carefully lower it. Once you have access to the pump, disconnect the fuel lines and any electrical connections to the pump. Remove the pump assembly and transfer any necessary parts from the old unit to the new one.
Install a new pump
Compare the new fuel pump with the original to verify that you have the correct part. Install the new pump and any reusable brackets or pick-up screens. Reconnect the fuel lines and electrical connections to the pump. If you had to lower the fuel tank, raise it back into position and reconnect any straps and fill lines.
Finally, partially fill the tank and run the vehicle to test for leaks. It is important to follow safety precautions when working with fuel. Work in a well-ventilated area away from any potential sources of ignition, such as open flames or sparks. Have a fire extinguisher on hand and do not smoke.

Fuel pump types: mechanical or electric
The cost of a fuel pump for a Mustang depends on the model of the car and the type of fuel pump. On eBay, there are several fuel pumps available for the Ford Mustang, with prices ranging from $150 to $300. The cost of replacing a fuel pump for a Mustang is estimated to be between $1,369 and $1,591, but this can vary depending on the specific vehicle.
Now, let's discuss the two types of fuel pumps: mechanical and electric.
Mechanical Fuel Pumps
Mechanical fuel pumps were the first type of fuel pump and were standard for many years. They use an internal spring-loaded diaphragm to pump gasoline from the tank to the engine. Mechanical pumps can be belt-driven, and there are two types: positive displacement and centrifugal. Positive displacement pumps are more common and work by squeezing the fuel through a small opening. Centrifugal pumps use centrifugal force to draw the fuel and are typically used in high-pressure applications.
Mechanical fuel pumps have several advantages. They don't make any noise and don't require additional plumbing or wiring. Additionally, they are less expensive than electric fuel pumps. However, they require more frequent maintenance and upkeep. They also have lower operating pressures, typically handling 10 to 15 PSI, while electric pumps can manage 30 to 40 PSI.
Electric Fuel Pumps
Electric fuel pumps use an electric motor to push gasoline or diesel fuel from the storage tank to the engine. They are usually located inside or very close to the fuel tank and are turned on and off by the engine's computer. Electric fuel pumps offer several benefits, including more efficient and consistent fuel delivery. They are also easier to install and less affected by changes in temperature, altitude, and other environmental factors.
Electric fuel pumps are generally more flexible and can handle higher pressures than mechanical pumps. They are also more cost-effective, with inline fuel pumps being a popular choice. However, they do produce audible noise, and there is a risk of fire if a leak is left unchecked.
In summary, both mechanical and electric fuel pumps have their advantages and disadvantages. The decision between the two depends on your specific needs, preferences, and vehicle requirements. Consulting a professional mechanic or auto parts specialist can help you make the best choice for your car.
