Your automobile’s engine relies on the fuel pump to deliver it fuel. Vielhaber’s Garage advises that the fuel pump lasts, on average, 100,000 miles. If you notice any of the problems listed below and your vehicle has at least one hundred thousand miles on it, there’s a strong possibility that the fuel pump is going bad. Don’t worry. We can test the fuel pump and replace it if necessary.
Engine Performance Trouble
As we just mentioned, the fuel pump supplies the engine with fuel. If it is unable to provide the necessary fuel when the engine needs it, the engine will struggle to perform. Specifically, the engine may hiccup at high speeds and lose power when it is under stress.
An Engine That Picks Up Speed
The opposite can also occur. A faulty fuel pump can send too much fuel into the engine and this will cause the engine to pick up speed. This can be unsettling if you haven’t pressed down harder on the accelerator. These engine surges can be caused by a bad fuel pump.
A Reduction in Gas Mileage
Whether your engine is sputtering or surging, you will notice a significant reduction in your vehicle’s gas mileage if the fuel pump is not operating efficiently. The engine cannot operate efficiently if the fuel pump is malfunctioning. Consequently, you will need to fill the tank more often.
A Reduction in Fuel Pressure
If you suspect that your fuel pump is going bad, you can test the fuel pressure to see if it has been reduced. If it tests lower than normal, this is an indication that the fuel pump is unable to pump the fuel through the system using normal force. You will need to replace the malfunctioning fuel pump.
An Overheating Engine
Another sign that your fuel pump is going bad is an overheating engine. This is strange, but it can happen. The fuel pump motor can overheat if the pump is unable to draw enough fuel through it to cool it off. When this happens, the engine can overheat, as well.
An Engine You Cannot Start
Finally, you may end up with a dead engine if the fuel pump is not working. You may also hear whining or humming sounds coming from the gas tank. These are signs that the fuel pump is unable to move the gasoline out of the tank and into the engine.
