Most vehicles on the road today, including the 1991 Porsche 944, come with an electric fuel pump. The fuel pump is located inside the gas tank and sends fuel from the tank to the fuel lines of the car. The fuel pump on the Porsche will fail from time to time and need to be replaced. However, it is important to properly troubleshoot the fuel pump to ensure that it should be replaced instead of another component in the fuel system.
Tools Used: Tools, Pliers, Ignition key, Fuel pressure gauge
Troubleshoot a Fuel Pump Not Working
Connect the fuel pressure gauge to the Schrader valve of your Porsche’s engine. The valve is located near the top of the engine and allows you to screw on the gauge.
