Fuel Pressure

I was wondering if anyone knows what the normal fuel pressure is at the fuel pump at startup of the car, when the car is running and then what is the normal pressure drop when the car is off.

Thanks in advanced!

That, you might need to ask the dealer about, cause not many of us have the experience with it.
