A functioning fuel pump is essential for any vehicle to function properly. It's responsible for pumping fuel from the gas tank to the engine of a car. Hence, if the fuel pump is damaged, the engine will struggle to run and the car won't be able to move. It's crucial to know the signs that often indicate a failing fuel pump so you can take the required steps to repair or replace it.
Check Engine Light
Often, the first sign of a failed fuel pump is that the check engine light (CEL) appears on the dashboard. That's because the fuel pump and the engine's other components are closely connected, and a failing fuel pump can affect their performance. Moreover, it's imperative not to ignore the CEL warning light as it may lead to serious problems. If the warning appears, take your vehicle in for an inspection by an expert mechanic.
When a fuel pump is damaged, it may struggle to supply the correct amount of fuel to the engine, leading to inefficient combustion. It can cause the engine to stutter or stall, often accompanied by a ticking sound. If your car engine is misfiring and making odd noises, it's likely a sign of fuel pump failure.
If your car's engine is working fine when you start the car and suddenly lose power while driving, it could indicate a fuel pump failure. When the fuel pump is not functioning correctly, there will be insufficient fuel delivered to the engine. This can cause your car to slow down or stop entirely.
Difficulty Starting the Car
If your car is having trouble starting, it might be time to check the fuel pump. A weak fuel pump wouldn't provide the required pressure to start the car successfully. If the pump is damaged or worn out, it may not supply enough fuel to get the engine running altogether.
Sometimes, your car may produce a noise that sounds like it's coming from under the rear seats. This noise may be heard while accelerating or when driving at a higher speed. While it may not always indicate a fuel pump failure, it's best to have a professional mechanic inspect it to confirm the source of the sound since this noise could be due to a damaged fuel pump.
Getting your fuel pump repaired before it stops working entirely is crucial for your vehicle's overall performance. In general, it's essential to watch for the signs mentioned above since they signal a failing fuel pump. If any of these signs occur, it's best to have a professional mechanic inspect your car to evaluate your options and take the necessary steps to repair the pump. Remember, ignoring these warning signs may lead to more significant, costly repairs.
