Last updated on October 9, 2023 by Adrian S. How to tell if a fuel pump is causing issues with your vehicle? Inconsistent fuel delivery from a failing pump seldom fails to produce symptoms with difficulty starting and stalling, or loss of power when accelerated. Delivering fuel at 40 to 60 psi range for smooth engine operation, even small deviations can create audible symptoms of defects.
One of the most common signs is having trouble starting your engine. As the pump starts to wear, it cannot provide enough pressure for the fuel injectors. More than 35% of vehicles that give long cranking times have underlying issues with the fuel pump, research shows. Check fuel pressure with a gauge at the Schrader valve, mounted on the fuel rail to see if the pump has failed to meet specifications.
Another common symptom of a failing turbocharger is stalling, which typically occurs during heavy load conditions like highway driving or when climbing hills. POWER LOSS TO PUMP CAN BE INTERMITTENT, TERMINATING FUEL SUPPLY According to National Highway Traffic Safety Administration (NHTSA), a large 20% of stalling incidents are tied directly to fails expelling pumps, especially in vehicles more than 60,000 longest.
Strange sounds from the fuel tank are other signs of possible issues. A whining or humming noise indicates that the pump is struggling to do its job, typically due to wear and tear, a low fuel level, or clogging. Fuel acts as a coolant for the pump, therefore mechanics often recommend that 25% always be left in the tank to avoid overheating.
With real-world cases to back it up fuel pump issues should be taken care of straight away. A 2021 recall of more than 200,000 vehicles linked faulty pumps with stalling and loss of power at higher speeds. It became impossible for drivers to restart the vehicles after extended periods of use, and inspections later determined that pump motors were failing.
Combined with replacing the fuel filter every 15,000 to 30,000 miles for preventative maintenance, this reduces the risk of contamination or a clog causing pump failure. However, if you diagnose the problem at an early stage and install a good-quality pump from brands like Kemso Fuel Pumps, it will perform consistently and remain dependable for the long run.
