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.

'94 Olds Bravada fuel regulator

This is not a small job, so unless you are confident and somewhat experienced with line level engine parts replacement, I dont strongly recommend it. The regulator on that is internal, under the upper intake plenum. If you are sure you only need the regulator, remove the upper plenun, which will require unattatching quite a bit of electrical connectors, lines, the throttle body, etc etc. You will see the regulator inside the lower manifold on one side, probably the cleaner side as when they leak they wash the dirt off that side(dirt is normal, comes in with the air, doesnt hurt anything). Its not truly difficult, but set aside 2 or 3 hours and may wanna snal some digital photos as you go to remind you of where everything was before you removed various pieces.
