What are the signs of a fuel pump problem?
Calling a fuel pump an essential component can be deemed an understatement; after all, any issues with the fuel pump can cause major drivability and performance problems. Some of the common signs of fuel pump problems include engine performance issues, hard starting, whining noise, and an inability to start the truck etc.
Why is my fuel pressure sensor not working?
If you try to start your vehicle’s engine and it consistently gives you problems, then your fuel pressure sensor is probably not sending a good signal to the engine’s computer. At first, the engine will eventually start after a few tries. But then, it will get to a point when it doesn’t start at all.
When do I get an error code on my fuel pump?
When the PCM sees voltage below the normal range in the main power circuit of the fuel pump relay, it activates this particular error code. This particular error code, just like other trouble codes, also illuminates the Check Engine light as well.
What to do if your fuel gauge is not working?
Because it’s an in-tank fuel pump, the hardest job is removing the fuel pump from the vehicle. Doing this test can help you pinpoint why the fuel gauge is not working. If this sensor is indeed working on your vehicle, then check the fuel gauge itself. This specific vehicle is a 2010 Subaru Impreza.
What to do if your fuel pump pressure is low?
What to Do if Pressure is Low 1 Place a shop rag over the fuel return line. 2 Pinch the line using a suitable pair of pliers to block fuel flow. 3 Watch the pressure gauge; if pressure remains low, either the fuel line is restricted, the fuel pump is receiving insufficient voltage, or the pump is worn out.
How can I tell if my fuel pump is bad?
I had a low voltage signal from the fuel pump, and a low pressure signal from the fuel pressure sensor. Either the fuel pressure sensor was bad, or the pump was bad. Putting my ear near the rear driver’s side wheel well, I could hear the erratic whining of the fuel pump, not a good sign.

What are the symptoms of a faulty fuel gauge sensor?
The first and most common symptom of a faulty fuel gauge transmitter is that the fuel gauge behaves irregularly and is not related to the actual fuel level. It can go from full to empty and back in a short space of time.
