Even though your car suddenly stalls while you drive and it gets hard to start the engine sometimes, you cannot say the issue is with the fuel pump with certainty. If your fuel pump is showing majority signs of having an issue, you need to test to confirm that the problem is actually with the fuel pump itself.

Now, you are probably wondering how to test a fuel pump, or whether you can do it yourself. Herein, the good thing is you don’t have to be a professional serviceman to run the test. With the help of a couple of inexpensive diagnostic tools, you will be good to go.

First, let’s have a look at what the symptoms of having issues with the fuel system are;

• The engine sputters at high speeds
• Car stalls when car temperature rises
• Vehicle losses performance while climbing hills or hauling heavy cargo
• When the car moves at a constant speed, all of a sudden it picks up and surges forward
• Noticeable poor gas mileage
• Car refuses to start despite making multiple efforts
• Unusual noise from the fuel pump

As I have said earlier, these signs aren’t enough to take any steps regarding fixing or replacing the fuel pump. Doing further test is a must to take any initiatives.
