Porsche is one of the most widely recognized names among luxury vehicles. People purchase this well-known brand specifically for its comfort, quality, and the power under the hood. But no matter the manufacturer, no matter the high-tech built into a newer model, there are going to be issues with various parts at some point or another. With many Porsche models, there are unfortunately frequent issues regarding the fuel pump. It is important to understand what these issues are and how they manifest.
Diagnosing a Bad or Failing Fuel Pump
Almost every modern vehicle has an internal combustion engine that also comes with a fuel pump. The fuel pump is responsible for bringing the fuel from the gas tank to the engine at appropriate pressure, which is based upon the performance of the vehicle at that time. When the key is turned on, the fuel pump is activated. You might hear it as a low whine or hum in your Porsche if you’re listening very closely for it. Fuel pumps on modern vehicles, because of their responsibility to supply the engine with fuel, cannot be overlooked when they present with signs of failure or issues. If you overlook the signs, it could cause serious issues with the driving of the vehicle.
As a vehicle owner, and especially as a Porsche owner, it is important to keep fuel efficiency in mind. You need to stay on top of your regular maintenance, especially for your fuel system. Failure to do so could result in fuel pump problems that could leave you stranded at an inopportune time. Below are some of the signs of a failing fuel pump that you can watch out for.
Signs of a Bad or Failing Fuel Pump
The dashboard in your Porsche is where you are alerted to any malfunctions in your car. If you are losing air pressure in your tire, there’s a problem with your engine, or you simply don’t have enough windshield wiper fluid, you will know.
Your dashboard will also tell you if your vehicle is running hot, which is one of the first signs you might notice of a failing fuel pump. Like all vehicles, your Porsche needs to operate at a steady temperature. If you notice that the temperature gauge on your dashboard is leaning toward the hot side, it could be indicative of a fuel pump issue. If the engine temperature not settling in its normal place as you drive, bring your vehicle into our garage for an inspection. Whether it is your fuel pump or something else causing the problem, overheating is a serious issue that should be addressed as soon as possible.
Beyond that, pay attention to your fuel economy. If you experience a noticeable dip in your fuel economy, it could be a problem with the fuel pump. Your fuel pump generally won’t simply go from functioning properly to failing all in one moment. Rather it is going to start to change slowly as it begins to fail. That said, you should notice a decrease in your fuel economy and performance. A decrease once or twice on unrelated separate occasions might simply be a fluke, but if you notice a continual decrease in performance it could be a problem with the fuel pump. Keeping track of your gas mileage can help you to identify problems with your fuel system and especially with your fuel pump early on.
Finally, one of the worst signs of fuel pump failure is having difficulty starting your engine. If your Porsche doesn’t start properly, it could be a problem with the fuel pump. It is the fuel pump that supplies your engine with fuel necessary to get the car going. Of course, there are other reasons why your car might not start, and fuel pump repairs can be costly. This is why having an accurate diagnosis performed with the appropriate equipment is absolutely necessary.
