Most fuel injected vehicles have a relay that controls the fuel pump so after the ignition switch has been on for about 5 seconds and the engine is not running, the fuel pump automatically shuts off.
I don't know what your original problem was, but I think if the car runs normally, you have probably fixed your problem. If you don't have a manual, you can probably go to the library and take a look at a manual that covers your vehicle.

When you hook the pressure test guage to shrader valve on fuel rail what it reads is what the pressure is from pump, around 60 p.s.i. all you need to do is hook up the guage and turn on key, you do not have to turn engine over, and if pump is good it will shoot up to 58 or 60 right now.

The only thing left in this system is the fuel pressure regulator. You need to check pressure before the regulator and after the regulator if there is the problem then you need to replace it. I hope this helps. Don't forget to rate my answer.

the fuel pressure if leaking could cause this the regulator is located under the intake plenum but you should smell gas .if you dont then most likely the pump is bad ,the pump will come on for 2 seconds when the key is on then go off it will not stay on with just the key on only when you crank it will it .so have your fuel pressure checked with a gauge.
