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.

another engineers wet dream. think of it this way . what is normally in the intake when the engine is running.. answer vacume, hence the regulator gets its vacume without a hose connected to it as its already in a full time vacume chamber.no hose required . ps be carefull to seat the regulator and o rings securely into the housing befor you reattach the secureing metal clip.
good luck chris

The fuel pressure regulator is located on the injector rail on top of the engine driver's side. #2 on the link i gave you is the vacuum tube to the fuel pressure regulator.
Thank you for using fixya and good luck.

it's on the end of the fuel rail. Vacuum operated regulator failure usually results in rich condition. You should check pressure to see if your pump is getting the job done. Cannot find the spec on pressure but a new pump for your car delivers 80-100 psi. Let me know if you have more questions.
