#6 Most signs of a failing fuel pump
The Fuel pump is an important component in the fuel system that serves to deliver pressurized fuel through the fuel line to be injected into the engine. When the key is turned on, the fuel pump is activated and pressurized, which can be heard as a quiet whine in some cars.
Because the fuel pump is the component responsible for supplying the engine with the fuel required for it to run, any issues with it can cause major drivability and performance problems. Usually, a failing fuel pump will produce one or more of the following 6 symptoms that alert the driver of a potential issue while engine running.
The first symptoms and signs of a failing fuel pump are the engine becomes harder to run on. This cause by the fuel inside of the fuel line is empty. The bad fuel pump sometimes makes the fuel ran back to the tank and leave the fuel line in an empty state.
A weak fuel pump may still pump fuel, but the engine may be difficult starting from the lack of fuel pressure. The empty fuel line causing the engine to have not enough fuel to start the combustion process inside the engine. As a result, the engine to become harder to run on.
In most cases, a weakened fuel pump can cause the engine to take more cranks to start than normal and require multiple turns of the key before it will start. This condition will add more problem like overdrawn electricity inside the car battery.
The next signs of a failing fuel pump are the engine acceleration feels slower, and some other times being interrupted. Even at certain times, the engine feels like had a loss of power when the accelerator pedal is suddenly pressed to accelerate.
This condition is caused by the small amount of fuel sprayed into the engine cylinder. As a result, the amount of fuel that enters the engine cylinder becomes less when it compared to the fuel pump under normal conditions.
This small amount of fuel will affect the engine power because the explosive power that occurs inside the combustion chamber has decreased.
One of the surest signs of a failing fuel pump is a sputtering engine — typically happens at high speeds. If you driving at a consistently high speed and the engine suddenly sputters before returning to normal operation, it may indicate issues within the fuel pump. In this case, the fuel pump cannot provide a constant stream of fuel to the engine at the ideal pressure.
The other signs of a failing fuel pump are car surging. A surge in the car often occurs because the resistance value of the fuel pumps motor changes. However, it occurs at a random or consistent speed. If this happens often, it may be because of problems within the fuel pump.
Other signs of a failing fuel pump are loss of power when the vehicle is under stress in several circumstances such as carrying a heavy load, driving uphill, or while accelerating.
The engine loss of power because the fuel pump cannot provide enough fuel demands in these situations. In these circumstances, the car will feel like it is unable to go or maintain the intended amount of power.
If the fuel pump is the cause, it means it can no longer regulate fuel pressure accurately and provide the appropriate amount of fuel to the engine.
Engine Stalling can happen because of multiple problems within a vehicle but pay attention when it happens frequently at high temperatures shown on the car’s thermometer.
A rising temperature paired with stalling often indicates a problem with the fuel pump motor. If stalling continues to occur with an increasing temperature gauge, it could indicate the fuel pump’s need for replacement.
