Yes, there are check valves that should maintain a minimum amount of pressure to the system. What you have described is called fuel pressure drop off. Basically, when the engine is turned off, the pressure quickly drops to 0. As a result, the next time you try to start it, the fuel pump takes a little longer to build the proper pressure. That is why I had you try cycling the key three times. In three times, the pump should have primed the system to start normally.
Would you like direction or a video to check fuel pump pressure, the pressure regulator, and fuel pressure drop off?
