Have you checked auto zone under specifications in repair guide? You have to register to use it.
If it turns free its not likely anything to do with the bracket swap its self. It is possible you broke a wire or the end of a sensor off during the process of changeing the bracket, check all connections and wires near the area.
SOURCE: fuel pressure regulator
How do you know that it is the regulator?
these 4.3 motors had a lot of trouble from 93 to 98, I know I had 2 of them.
What happened to mine was that the intake kept getting very carboned up. After I would clean it, the truck would run fine for about 5 or 6 months, then same thing.
Theres actually a class action lawsuit about this that I believe has been settled, you may have recourse if you bought it through a dealer. Good luck.You'll need it.
SOURCE: Where is the fuel pressure regulator located at in a 94 bravada
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.

It can be done but it is very time consuming.
I use an 87 Astro van intake sensors and computer on my 86 OMC.
After six years I am still playing with it.
Runs good and easy on gas.
Got lots of info from DIY-EFI.
You HAVE to change programing in the computer.
I am running a closed loop system with one oxygen sensor in the starboard manifold.
Your 94 computer is not as good for a boat because it also controls the transmission.
Just to give you an idea what your in for.

You have to put the Ignition Control (IC) system in the bypass mode by disconnecting the "set timing" connector. This is a single wire sealed connector that has a tan with black striped lead. The location of the "set timing" connector with a Powertrain Control Module (PCM) controller is near the PCM connectors in the passenger compartment. Unplug connector (tan/black stripe) start engine set timing to 0 TDC, TURN OFF ENGINE, re-connect timing connector
