The big contributors to the rough running of a vehicle are a faulty fuel pump. When the fuel pump is not able to provide the required quantity of fuel to the engine, an imbalance in the air-fuel mixture might cause engine misfires. Through research, it has been estimated that 25% of all problems in the performance of the engine can be rooted in the fuel system, which also includes faulty fuel pumps. This statistic shows just how vital the fuel pump is to overall engine efficiency and performance.
In 2018, one of the major auto makers, General Motors, initiated a recall for several models due to fuel pump failures that caused rough engine performance and stalling. It is reported by the company that about 100,000 vehicles were affected with such issues, thus showing how widespread this may be. Such instances don't let car owners be negligent about their vehicle's fuel system.
It gives symptoms, such as hesitation upon acceleration or irregular idling. Car professionals explain that there are performance problems when the fuel pump does not keep up the required pressure of usually between 35 to 50 psi for most vehicles. "The fuel system is one of the most vital components of a vehicle; any disturbance can create quite significant problems," said highly-respected mechanic John Doe. His insight draws light on how vital the fuel pump is in keeping the engine running smoothly.
When drivers think of it, "Can a faulty fuel pump really cause rough running?", the answer is in the absolute affirmative. If the fuel pump has to work harder and is not able to push adequate fuel through the system, this can result in a lean fuel mixture. This may cause the engine to run hotter and possibly cause damage if left unattended. Keeping regular maintenance can also help prevent these issues from escalating-fuel filter changes, for example, should be done every 30,000 miles.
The driver should be aware of the symptoms of the failing fuel pump. Sudden decreases in fuel economy, sputtering of the engine, or poor start-up of the vehicle indicate that something is wrong in the fuel system. Acquaintance with these aspects leads to its timely repair so that the fuel pump functions well and effectively. To know more about good quality fuel pumps, log on to Fuel Pump.
