Need help. Fuel Pump is ding?
Recently I mounted, right before the injectors manifold, a pressure gauge to see the fuel pump's life. I was inspired to do that cause now is useful, unfortunately. It shows 2,5 when I should be getting at least 3bar.
Two nights ago:
I was driving around when the yellow light for empty tank came on.
I got some fuel (half of tank) then drove away from the gas station...
50m later disaster I lost all power, engine died slowly as it was running out of fuel. Pulled off, checked fuses. All ok.
Turned ignition key, noticed the fuel pump was barely noticeable compared to before (much noisier). I was thinking WTF.
A friend came and towed me. Later at a crossroad tried again to start and the pump started delivering again the fuel to the engine.
Today:
Parked the car in front of a service shop. Got back, tried to start it, again no buzzing from the fuel pump and the engine was running roughly struggling on the last drops of fuel. Again, almost close to yellow light and empty tank.
Managed to push the car into a close, thank God, fuel station, and filled half a tank again. Again no start. Took the fuel pump cover apart, to reveal the pump. Took out the IN and OUT fuel lines from the pump and run a test on the standalone pump. It started to spit the fuel. Reconnected the lines, the pressure gauge showed 2,5bar, engine started again.
What are your ideas???
These pumps have some filter inside, should I be cleaning it? I honestly don't know the age of the pump...
Is maybe the flotor of the pump that gives the sensor for fuel level out of range and when I believe I still have some reserve (on the yellow light) instead the tank is empty?...
