Question about Cars & Trucks
Look on the back side of the engine just to the drivers side of the distributor. You will see the two fuel lines. The test port will be on the larger line. It usually has a black plastic cap over it.

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.

The fuel pressure regulator is located under the intake plenum attached to the six in one fuel injector.They leak quite often causing hard start conditions.The injector is also known as a spider injector which will come with the regulator .

Yes, on my 2002 xl-7 the low side port is behind the grill as ibass215 says. The cap is light green and marked with an "L". Thanks Susuki, couln't you find a more hidden place?
