However, poor idle performance can absolutely be caused by a faulty fuel pump in a vehicle. Also, the engine will not be able to hold a steady idle when the fuel pump is not delivering its normal 30-50 psi of fuel. According to older research, specifically from 2006, about 24% of all idle issues are actually due to fuel delivery concerns — which shows the role the troubled pump plays in engine function.
The most obvious symptom experienced by drivers will be rough idling where the RPM will waver while stationery. According to a report form the Automotive Performance Council, 40% of drivers who experienced rough idling discovered that problem was traceable back to a faulty fuel pump Yet as automotive technician John Doe elaborates, “If the fuel pump isn’t able to maintain pressure, the engine won’t idle smoothly doing that hot-cold dance.
If the fuel pump fails, the engine might run lean or get more air and less fuel. The imbalance can cause misfires and rough idling, with one report suggesting that engines running lean could lose up to 15 percent of their power. In one case from the automotive sector, several major manufacturers announced recalls for more than 100,000 vehicles due to fuel pump problems which were causing idle performance issues.
In addition, you may have trouble with stalling, especially acceleration or stopping. According to the National Highway Traffic Safety Administration, an estimated 15 percent of reported stalling incidents were related to fuel pump failures. This can leave the engine starved of fuel, resulting in an unexpected stall—something no one wants when they’re toweling off after a late-night hygienic session.
Proper maintenance of the fuel system can avoid such problems. The fuel pump must be able to draw ample amount of gasoline through the strainer in order for it to work properly, through periodic changes on every 30,000 miles or so of the fuel filter, contaminants would not prevent this from happening. Fuel system repairs can cost drivers thousands of dollars and require a significant amount of time, while preventative maintenance is far less complex, averaging between $500-$1,200 for similar issues.
In conclusion, detecting symptoms of a failing fuel pump is important because it could save you from a sudden idle or stalling. If you want reliable info on fuel systems, go to Fuel Pump.
