Solving or troubleshooting an intermittently failed fuel pump can save time and money, avoiding more serious engine problems. One reason they are such a pain in the, um, neck is that approximately 20% of all fuel pump failures occur when the darn things only half-die. Check fuel pressure, which is one way to diagnose the problem. Generally a good fuel pump should fall in the 40 to 60 psi range, use a fuel pressure gauge to see if the pump is reaching adequate flow.
For example, a study conducted by the Automotive Maintenance Association showed that 25% of drivers suffer from stalling due to fuel delivery issues—and most because the pump periodically fails to deliver fuel. Low pressure readings, lower than the recommended levels) could be a sign of fuel pump problems. As automotive expert Mike Anderson points out: “Fuel Delivery should remain consistent to achieve engine performance / longevity.”
Yet, there is another very important step to take before rushing out to replace your fuel pump… checking the vehicle’s electronic circuits for proper power to the fuel pump. The pump’s performance can be affected by the intermittent failures in case of faulty wiring or corroded connectors since electrical resistance will add up to the problem. Industry data reveal that some 15 percent of fuel pump malfunctions are due to electrical, thereby highlighting the importance of checking the wiring harness for visible damage.
Moreover, if you are hearing unusual clicking from the fuel tank is also an indicator. A non-failing fuel pump will work smoothly and quietly, but if you hear a high-pitched whining noise or a buzzing sound that is likely close to giving way. If you do, it may be time to start to think about replacement. The year 2019 witnessed a recall of more than 100,000 vehicles due to fuel pumps producing loud noises, further signifying the need for proper attentiveness.
Also, check the fuel filter — if it is clogged and restricting fuel flow, the result can look a lot like a failing fuel pump. If you haven’t replaced the fuel filter in 30,000 miles or so, it’s increasingly advisable to replace it because a clean filter allows for great delivery of fuel. Auto tech Lisa Ray observes, “Maintenance is the key; simple maintenance checks could stop a downside before it becomes major.
You would also want to run a diagnostic scan on the car onboard computer. A lot of cars actually keep trouble codes that relate to the performance of their fuel systems so you can narrow down specifically what seems to be off. Since the diagnostic tests replaced only codes for fuel delivery, it has to be something with the way the fuel pump is working out your troubleshooting.
So to conclude this segment, fixing an off-again on-again gas pump should strictly also be good for listening with our ears to know if there is a strange sound, check with eyes if the fuel filter looks good, and start plugging in diagnostic scans. Improving these factors, can improve the past of going right through vehicle repairs and services. To learn more about performance fuel pumps, please visit Fuel Pump.
