Depending on the engine and fuel type...
Diesel - direct injection fuel pumps generate approx 1600 bar (23 200 psi) for common rail systems, as for the pump-nozzle injector diesel systems (pumpe - duse German translation), the pump can generate over 2000 bar (29 000 psi)
Gasoline engines have electric fuel pump located inside a fuel tank, and produces approx 3 bar of pressure (43 psi).

Is a whirring sound from a fuel pump normal or is it malfunctioning?
Just be glad it is making a noise. that is a sign it is working.

check the injector, may be under the intake.

The fuel filter could be blocked.
Your 2004 Chevy Malibu won't start tries to turn over but won't start will start with ether but won't stay running?
fuel filter,pump,pressure regulator? security sensor issue? The fuel pump may not be working, if the fuel pump relay (if installed), is bad
How do you know fuel pump is working?
Do a fuel pressure check-no fuel pressure means defective fuel pump-
How do you test the electric fuel pump on a 1990 Dodge Dakota?
you will need to hook a pressure gauge up to the fuel rail. If the correct pressure is not obtained then the pump is bad. If too much pressure then your fuel pressure regultor is not working. You will need to find out what the normal operating PSI range is for this pump first.
If you can hear the fuel pump kick on when you turn the key on is the fuel pump still working.?
If you hear the fuel pump run that is a good sign it is working however, a fuel pump pressure test would tell you if the pump is meeting the required pressure.
Why does my 1986 Chevy s10 2.5 will not pump fuel fuel pump is working?
The fuel pump may be running but it may not put out enough fuel pressure. Have the fuel pressure tested. I am assuming the fuel filter has been changed.
How do you tell when your cars fuel pump needs to be changed?
A fuel pressure test can determine if the pump is working properly or not.
How do you know if your fuel pump is not working in your 1996 Audi a4?
A fuel pump pressure test could determine that.
CheckED relay to fuel pump and fuel pump BOTH ARE WORKING what else can you check?
Fuel pressure. Need more info to give you required fuel pressure needed to run properly.
How much fuel pump pressure for 1985 Toyota?
the fuel pump in common rail diesel generates the highest pressure eg 1600Bar. whereas normal fuel pump generates not more than 10-15 psipressure
What causes no pressure in a fuel injector?
I would suspect either a clogged fuel filter or a defective or not working fuel pump.
Does a fuel pump just give out or does it gradually deteriorate?
Both - a failing fuel pump will lose pressure, and the engine will run as though it is starving for gas. Checking the fuel pressure checked and getting lower pressure readings than normal will indicate the need for a new pump.
What does a fuel pump pressure sensor do?
The fuel pump pressure sensor monitors the fuel pressure of the vehicle.
Why does my 91 Chevy Camaro start when sprayed with starter fluid but not on its own?
Bad fuel pump or fuel pump relay. Maybe a bad fuel pressure regulator. You need to determine if the fuel pump is working.
