Various symptoms may point to the need for repair of a Fuel Pump. The leading complaint by motorists is that the car does not start easily. A failing Fuel Pump may not provide a sufficient amount of fuel pressure to the engine, which generally runs at a pressure level of 30-80 psi. If the pump can barely struggle along, then the engine will take longer to crank before it starts, or maybe not start at all. In fact, only a 10 psi drop in fuel pressure will cause considerable starting problems, and that shows how important the Fuel Pump is.
The next most enclosing thing showing the bad condition of the Fuel Pump is when the engine stalling starts: if the pump does not supply fuel continuously, an engine may stall when driving-on uphill drives or on acceleration. This may be due either to an obstructed fuel filter or because of internal pump failure. Indeed, nearly 5% of drivers whose vehicles were recalled by Ford reported a stalling problem caused by malfunctioning Fuel Pumps in a recall which Ford issued in 2019 for over 700,000 vehicles where defective pumps caused unexpected shutdowns.
Other symptoms that can be expressed by drivers are decreased fuel economy. A weak or failed pump can make an engine run rich or lean, which impairs the efficiency of combustion. This misbalance can lead to an increase in fuel consumption by 10% to 15%, which is costly but also indicative of underlying problems with the fuel delivery system.
Another symptom of a malfunctioning Fuel Pump could be strange noises around the fuel tank. Whining or humming sounds may suggest that the pump is required to do more than what it ought to do, either due to wear or due to some damage in certain ways. If these noises get louder, especially when acceleration is being performed, it becomes quite necessary that further investigation into this be done; if neglected, this might lead to complete failure.
As once said by Henry Ford, an automotive expert, “Quality means doing it right when no one is looking.” Regular maintenance and quick response to these warning signs can save you from further damaging your Fuel Pump and also will keep the costly repairs away.
