My friend, I suggest you go by your local Auto Parts Store and purchase a Haynes Repair Manual on this vehicle. There are many sensors and electronic controls involved with this engine as I'm sure you already know. Any one of these can memic something that "it is not".
If your problem is the Pressure Regulator, it is located inside the "Tunnel Ram" intake manifold along with the multiport fuel injection system.
Now,,, before I went through the trouble and expense of going into the Intake Manifold, I would run the EMC in Diagnostic Mode and see if there are any codes present.

not sure on an s10 but it should be close to the same position as a full size truck. Should be in the engine compartment, drivers side on top of the motor on the fuel rail. Held in by a snap ring or a c ring. When you buy your part, ask the salesman and they should be able to tell you for sure.

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

Two places to look...if you have separate injectors for each cylinder then regulator should be at the front end of the fuel rail. If you have throttle body injection it is on the throttle body itself.
