Symptoms of a Bad Fuel Pump
The fuel pump is responsible for pumping the fuel from its tank to the engine. The fuel that is highly pressurized is a sign of efficient combustion in internal combustion engines. If the fuel pump fails, the pressure it exerts in the fuel will be lower than needed. It can bring to the wrong combustion of the air-fuel mixture. That’s why it is always important to know the symptoms of a bad fuel pump to keep your car running longer , because the worn out fuel pump can cause failure of other parts of the fuel system and even problems with the parts outside of the fuel system. Let’s look at some symptoms of a bad fuel pump.
A sputtering sound coming from the engine
One of the common problems can be stalling and sputtering at high speeds if your vehicle’s fuel pump is damaged. This clicking noise can be a sign of other issues as well, but the most probable is a bad fuel pump. That’s why you shouldn’t ignore this sound, as soon as you hear the clicking noise, try to find the main reason, if it’s a fuel pump, replace it as quickly as possible to avoid other failures and to save money on fixing it.
Loss of power while accelerating
It’s hard to recognize a bad fuel pump with this sign because the loss of power can also be due to a bad fuel pressure regulator or worn fuel lines . Anyway, if you are having loss of power while accelerating, then always check the fuel pump for any damages to make sure about its efficiency.
Loss of power under stress
Carrying a lot of stuff in your car? And you noticed that your engine loses power? In this case, it can be because of a failing fuel pump. We always recommend not to ignore this issue even if it happens only when your car has a lot of weight. Replace it if needed.
While you are driving at 60 MPH your car randomly surges up to higher speeds on its own. It’s most probably because of a weak fuel pump. Surging speeds happen when the damaged fuel pump is delivering irregular resistance within the motor and at time kicks harder than it is supposed to. This can happen as well when your engine old fuel filter needs to be replaced, but in most cases, it can be a bad fuel pump.
To replace the broken fuel pump by yourself, we recommend doing so only if you have any experience of doing that or high skills in the automotive technology. If not, then it is better to take your car to the specialist or a trusted mechanic to check it and to replace a failed fuel pump if needed.
