If your Porsche is losing power when you drive up hills, this is a sign that the fuel pump is dying. The Porsche needs extra fuel when the engine is under stress, and driving up steep inclines puts the engine under stress. Consequently, if the fuel pump is unable to supply the additional fuel, your Porsche will struggle under these conditions. Kinetech Motor Werkes explains that this is just one sign of a malfunctioning fuel pump. Here are the others.
Sputtering Engine
You will also notice that your Porsche’s engine sputters when you are driving at higher speeds. This is because the engine also needs extra fuel to go faster. Consequently, you will continue to have engine performance problems at high speeds until you replace the faulty fuel pump.
Poor Fuel Economy
Both of these engine performance problems will reduce your Porsche’s fuel economy. Unfortunately, when the fuel pump is unable to maintain the fuel supply to the engine properly, the engine loses most of its efficiency. As a result, you will see a significant reduction in your gas mileage.
Low Fuel Pressure
There will also be a reduction in your Porsche’s fuel pressure. The pressure can be tested using a fuel pressure gauge that you can buy over-the-counter. We can also test your fuel pressure if you would prefer not to do it yourself. The pressure must be within the recommended range.
Overheating Engine
If the fuel pressure is too low, this is not only a sign that your fuel pump is dying but your engine may also overheat. This is because the fuel pump relies on the gasoline it pulls out of the tank to keep its motor cool. If there isn’t enough fuel to cool the motor, it will overheat and so will your engine.
Hard or No Starting
Finally, if it has been difficult to get your Porsche started lately, it’s possible that the fuel pump is going out. Eventually, you won’t be able to get your Porsche started at all. This is because the fuel pump has died completely and is no longer drawing fuel out of the tank.
