The importance of fuel pumps
Fuel pumps inject gasoline from the fuel tank into the engine in most cars and trucks. Your car cannot function without a working fuel pump. If the pump stops working, your car stops driving.
Most modern vehicles have electric fuel pumps mounted to their fuel tanks, though some are equipped with inline or mechanical style pumps. Because the fuel pump is responsible for supplying the engine with fuel, issues with it can lead to major performance problems and costly auto repairs. Most fuel pumps eventually require replacement.
A damaged or failing fuel pump will produce one or more of the following symptoms. If your vehicle starts displaying any of these signs, or you suspect your fuel pump may be misbehaving, bring your car into one of HEART Certified Auto Care’s three convenient locations in Evanston, Wilmette, or Northbrook for a free inspection, and we’ll diagnose the problem right away.
Engine Sputtering at High Speeds
One of the best indications that your fuel pump is failing is a sputtering engine while driving at consistently high speeds. If your vehicle sputters suddenly and then resumes regular performance, there may be something wrong with your fuel pump. Sputtering occurs when the pump struggles to supply a constant steam of fuel to the engine at the proper pressure.
Decreased Fuel Pressure
Low fuel pressure can lead to engine misfires, low acceleration, rough idles, and engine stalls. If your check engine light is on and your car has been stalling out, you may have a fuel pump failure. Bring your vehicle to HEART Certified Auto Care and let us take a look at that pump.
Losing Power when the Vehicle is under Stress
When climbing a hill or hauling heavy cargo, your car is under stress. If you lose overall power while performing stressful tasks with your vehicle, your fuel pump may be too weak to keep up with the demands of driving.
Inability to accelerate
Irregular resistance within the fuel pump motor can lead to your car slowing down and being unable to accelerate. Failing to accelerate is a good sign that your vehicle’s fuel pump needs inspection.
Decreasing Gas Mileage
If your vehicle typically gets decent gas mileage and then suddenly starts hogging fuel, there could be an emergency under the hood. Fuel pumps have a relief valve that will allow more fuel than necessary to flow into the engine system if it fails to open. If you’re refueling your car more often than you used to, it’s time to bring your car into a HEART location in Evanston, Northbrook, or Wilmette to check under the hood.
Engine Not Starting
If you face any of the above symptoms and ignore them, eventually your engine will refuse to start. Fuel cannot reach the engine upon ignition when a fuel pump completely malfunctions. Check for blown fuses and/or low pressure in the fuel line to diagnose a fuel pump malfunction or bring your vehicle to one of HEART Certified Auto Care’s three locations in Evanston, Northbrook, or Wilmette for auto care you can count on. Whether you need tires, an oil change, or more, HEART will restore your faith in auto care.
