You can expect to get about 100,000 miles out of your Mazda’s fuel pump. After this mileage milestone, Mazcare advises that the fuel pump will eventually go bad. As you can imagine, a faulty fuel pump can cause all sorts of problems with your Mazda’s engine. We are going to list the signs that your Mazda needs a new fuel pump below.
Mazda Performance Problems
Engine performance problems associated with a malfunctioning pump include sputtering, lagging when under stress, and surging. The former two happen because the pump is unable to supply the Mazda’s engine with the extra fuel it needs. The Mazda’s engine will surge if the pump is sending extra fuel into the engine when it doesn’t need it.
Reduction in Overall Fuel Economy
This will reduce your Mazda’s overall fuel economy, which can be a real problem if you are living on a tight budget. You don’t need to head to the service station more often if you are having financial problems. It’s better to spend the money to get the fuel pump replaced so your Mazda’s engine performance and fuel economy are restored.
Increases in the Engine’s Temperature
Another thing a faulty pump can do is increase your Mazda’s engine temperature. The temperature should never rise above 220 degrees Fahrenheit. If the pump motor starts to overheat, this excess heat can make its way into the engine and increase the temperature above that maximum. When this happens, your Mazda’s engine will overheat.
Unusually Low Fuel Pressure
One thing that we do to test the fuel pump is to check your Mazda’s fuel pressure. If it is unusually low, it’s a safe bet that the pump is not able to produce the pressure needed to maintain enough fuel in the engine for optimal engine performance. You can also test the fuel pressure at home with a special gauge that you can get at an auto parts store.
Inability to Start the Mazda’s Engine
Finally, there might come a time when your Mazda will end up with a dead engine because it doesn’t have any fuel pumped into it. No matter how hard you try, you will not be able to get the engine started. This is a sign that the pump has died completely and is no longer functioning, i.e., moving gasoline into the engine.
