Your Mazda was equipped with the fuel pump when it was assembled in the factory. The factory fuel pump lasts approximately 100,000 miles. If you drive a high-mileage Mazda, you may be on the road to a faulty fuel pump. Mazcare is going to list the signs of a dying fuel pump below so you can bring your Mazda to our shop at the first indication of trouble. The sooner we address the fuel pump the less chance you end up stranded with an engine that you cannot start.
An Overheating Engine
One unique sign of a faulty fuel pump is an overheating engine. The fuel pump can overheat your Mazda’s engine if it does not draw enough fuel out of the tank to keep its own motor cool. Once the fuel pump motor gets too hot, the heat is transferred into the engine. Consequently, your engine will overheat, too.
Reduced/Low Fuel Pressure
Another indication that the fuel pump is malfunctioning is a reduction in your Mazda’s fuel pressure. The fuel pressure should always be within the range specified in your owner’s manual. If the pressure is below this range, the fuel pump is malfunctioning and not producing enough fuel pressure to sustain engine performance.
Reduced/Poor Fuel Economy
Consequently, your monster will suffer from poor fuel economy. This can happen because the engine is burning through whatever fuel it gets quickly in order to start and run. Unfortunately, you will continue to notice a reduction in your fuel economy until you get the dying fuel pump replaced and the proper fuel pressure restored.
Sputtering at High Speeds
This lack of fuel pressure in the engine will cause the engine to sputter at high speeds. This is an indication that your Mazda’s engine is fuel-starved. In other words, it doesn’t have enough fuel in the combustion chamber to maintain the speed at which you are driving. You may also have problems accelerating your Mazda.
Stress Engine Power Loss
Aside from struggling to operate at high speeds, your Mazda will also struggle to operate when it is under stress. This, too, is caused by fuel starvation. An example of your Mazda being under stress is driving up a very steep hill. If your Mazda loses power under this driving condition, the fuel pump is not working properly.
Hard Starts/No Starts
Finally, your fuel pump will eventually die and you won’t be able to start your Mazda. This, obviously, leaves you stranded wherever you are. This is why we mentioned above that it is important that you address any of the symptoms listed above as soon as possible. This prevents the fuel pump from dying completely.
