There are five symptoms and conditions that will lead you to replace a fuel pump. Fuel pumps are usually good for between 100,000 and 150,000 miles. If your car experiences noticeable loss of power, and it stalls or struggles to pick up speed especially when you are accelerating; this may indicate a failing fuel pump. Research from the National Institute for Automotive Service Excellence reveals that 20% of fuel problems result in a bad fuel pump.
The other important parameter is having problem in the engine start. If the engine will turn over but not fire up it could possibly be that you arent getting enough fuel to your pump. Industry standards dictate a good fuel pump will be able to keep the correct amount of pressure (30-60 psi, depending on year make and model). If the pressure falls off drastically, it may be time to change the fuel pump.
Also, a going-fuel pump would make the fuel gauge display unpredictable readings or remain at empty instead of full even though there is still gas.

When the pump stops working, it also makes different sounds like whining or buzzing type of noise coming from fuel tank. According to Auto Repair Monthly, the cost of repairing a fuel pump replacement for ANY vehicle can be around $400–$800.

John Davis, an automotive expert, comments on the same stating “The fuel pump has no warning life and will just fail unexpectedly. An ounce of prevention by replacing the pump proactively can save you a lot in repairs as well as inconvenience.”
