Do you suspect that something is wrong with your vehicle's fuel pump and you are unsure how to diagnose the problem? If so, it will help to know some of the common signs that can come up when this part is in need of replacement.

Error Code Problems

One of the first things that you may notice is that a service engine light soon appears on your dashboard. You'll need to take your vehicle to a local auto shop to have them tell you the exact error code that triggered the warning light. One common code associated with the fuel pump is P0087, which identifies a problem with your vehicle's fuel pressure. You may have a problem with the fuel pump's driver module that requires your attention.

Engine Problems

The engine may behave oddly because the engine is not getting the fuel that it needs. You could notice this immediately when you start your vehicle, since the engine may struggle to turn over or not start at all. 

There are also various symptoms that can happen while you are driving, such as the engine struggling due to not getting enough fuel from the fuel pump. A vehicle can stall when you come to a complete stop at a red light or stop sign, or the engine sputters when you go to accelerate. You can also have a problem where the engine seems to be losing power and cannot accelerate to the speed you want to go.

Noise And Odor Problems

A bad fuel pump can also cause a distinct sound that seems like it's coming from the fuel tank. There could be a buzzing or whining sound. While the fuel pump normally makes a low pump sound, it can get louder as the fuel pump becomes defective. If the fuel pump is causing fuel to leak out of the vehicle, you'll also smell gasoline when you're outside the vehicle. 

Fuel Gauge Problems

A problematic fuel pump can also cause a problem where the fuel gauge reads the improper amount of fuel in the tank. In some situations, the fuel tank may not even show a reading at all. This is because the fuel pump has a sending unit that can become defective over time. While this is a problem that can usually be fixed on the fuel pump, replacement may be necessary.
