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.

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

Multi point injection systems run at about 45-55 psi. When the key is
turned on,engine off, fuel pump will run for a short time to prime the
fuel rail. At this time the tester should read normal pressure or a
You need to use a pressure gauge and run it in-line with the fuel lines. Pop the hood and look to the left. Just above where the strut mounts you will see a round silver filter. You need to remove the fuel line there and place your pressure gauge in line of that.
Let me know if you need any more help.

REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4
Before performing any service on the front or rear TBI unit, you must place the unit in a suitable holding fixture such as J-9789-118, BT-30-15, or equivalent. If you dont place the unit in a suitable fixture, the throttle valve may be damaged.

Do not immerse the fuel meter cover (with the pressure regulator or accumulator) in any type of cleaner. Immersion will damage the internal diaphragms and gaskets.
