First thing you should know： Fuel pumps are not part of a regular maintenance schedule and only need to be replaced when they fail. Most fuel pumps should last well past 100,000 miles, but it doesn’t mean yours won’t fail before 100,000 miles.
Here are some of the symptoms of pump failure:
1. A well-functioning fuel pump generally gives off a soft humming noise when your vehicle starts up. If instead you hear a sharp whining sound from your fuel tank, then this is very likely a sign you need a new fuel pump.
2. If your car is not starting well but you do not hear the sharp whining noise mentioned above, it is possible that your fuel pump is still functioning, but weakly. This means that the amount of pressure the fuel pump delivers is less than necessary. If the fuel pump is weak, this means that it takes more cranks to start the engine.
3. Sudden lost of speed or power while driving
4. If you notice an increase in fuel consumption, requires stepping on the gas to give the necessary power, it could be the pump’s fault. There are valves in the pump, it might not give too little or too much fuel to the engine”

Fuel pumps are usually found inside of the fuel tank. So its not easy to check it.
Here’s simple method to check if a fuel pump is turning on is to listen for it. Open the fuel door, remove the fuel cap (if your car has one), and turn the cars ignition to “On.” Put your ear next to the fuel door and listen for a humming noise. If you don’t hear any noticeable action, the pump is likely not working.

You should look for a pump part that is compatible with your vehicle, and search for that part# on the web. I bookmarked an eBay store, they sell good quality pumps. I put one in a couple of years ago and it’s still running great. Here is the link https://www.ebay.com/str/originalpartsgiant，I hope this helps you out.”
