When I turn the car on the fuel goes on and it gets pressure but once the pump shuts down I loose the pressure any ideas I have a new pump and a new regulator
Pinch off the return line. Pressurize the system and see if the pressure drops. If it does, it is injectors. If it doesn't, it is the fuel pressure regulator.
