Your automobile relies on the fuel pump to draw the gasoline or diesel fuel out of the tank and move it into the engine so it can be burned in the combustion chamber. Service Masters can replace your fuel pump if it is going bad, which it might be if your vehicle has over 100,000 miles on it. We are going to talk about the signs of a bad fuel pump below so you know what to look for in your car, truck, or C/SUV.
A Constant Overheating Engine
One strange side effect of a faulty fuel pump is an engine that overheats constantly. The fuel pump has its own motor to help it operate. This motor relies on the fuel drawn from the tank to keep it cool. If the malfunctioning pump cannot draw enough fuel to cool the motor, it will overheat. This can actually make your engine overheat every time you drive your automobile.
A Reduction in Fuel Economy
A malfunctioning fuel pump will also reduce your vehicle’s overall fuel economy. This reduction may be subtle at first, only to get worse as the fuel pump gets worse. Anytime the engine is not receiving the fuel it needs, it will suffer and struggle to run – more on that below. Consequently, it will burn away the fuel it does have quickly, and you won’t get as many miles to gallon.
A Reduction in Fuel Pressure
The fuel pump helps to keep the fuel pressure within the necessary range to sustain engine operation. If the pump is dying, there may be a significant reduction in fuel pressure. This will cause engine performance problems and could even make it impossible to start your car.
A Reduction in Power When Stressed
The engine requires more fuel to sustain speed when it is under stress. For example, the engine will need excess fuel to sustain speed when you drive the vehicle up a steep mountain road. If the fuel pump fails to push more fuel into the engine, the engine will lag.
High-Speed Engine Sputtering
The same is true when you are driving at higher speeds. You need more fuel to sustain a steady speed. If the pump cannot move enough fuel into the engine, the engine will start to sputter and lag. This can definitely be a sign of a faulty fuel pump.
