Your car’s fuel pump is one of the most important components in your vehicle. Although it may seem that your car could not run without one, this is not always the case. Some cars just run poorly with a malfunctioning fuel pump.

1. How to Know It's Time to Replace Your Fuel Pump
Your car’s fuel pump is one of the most important components in your vehicle. Although
it may seem that your car could not run without one, this is not always the case. Some
cars just run poorly with a malfunctioning fuel pump. Even though your car may still be
limping around, continuing to drive with a malfunctioning fuel pump is harmful to your
vehicle. For this reason, you need to know the signs that indicate your fuel pump is
acting up. Otherwise, you may become stalled in traffic or end up stranded somewhere.
Understanding Your Car’s Fuel Pump
The fuel pump is responsible for moving the fuel from your car’s gas tank to its engine. If
this pump is not working correctly, your engine receives an inadequate amount of fuel.
Several symptoms indicate your fuel pump is malfunctioning:
• You may hear a high pitch sound when you first turn on your engine
• Your car may be difficult to start or does not start at all. If your car is stuttering,
sputtering and stammering as you try to start it, your engine is not getting the
fuel it needs
• Stalling during operation is another concern.
• Slow acceleration
• Jerking while driving

2. While a car could stall and sputter for numerous reasons, you can determine if
the problem is your fuel pump by performing a simple test:
1. Drive your car into your garage or to a silent environment.
2. With the car turned off, place the key into the ignition and turn it to ‘accessory’ or
‘on’ – do not try to start the engine.
3. If your car has an electric fuel pump and fuel injection, you should be able to hear the
pump turn on. It will make a buzzing or clicking sound.
If you perform the first test and you cannot hear your fuel pump, try this test:
Use a fuel pressure gauge to ensure enough gas is reaching your engine. If you do not
own a fuel pressure gauge, bring your car to Premier local auto repair shop Cape Coral
so one of our technicians can perform this test for you.
1. Near the engine, you should see a fuel pressure valve. This is where you attach the
gauge.
2. Find your car’s recommended fuel pressure in your owner’s manual.
3. Compare your fuel pressure measurement with the recommended pressure.
4. If your vehicle has less pressure than it should, this is a sign your fuel pump is
malfunctioning.
Other Problems that can Cause Incorrect Fuel Pressure
A few other issues could cause your fuel pressure to be incorrect.
These Issues Include:
• A Failing Fuel Pressure Regulator
• An Obstruction in the Fuel Line
If you notice that your fuel pressure is too high, it could be the fuel pressure regulator.
Whether you need to have your fuel pump replaced or a new fuel pressure regulator
installed, the certified technicians at Premier Local Auto Repair Shop Cape Coral can
diagnose and then correct any problems you are experiencing with your car.
