There are 2 torx screws on the fuel rail, driver's side of engine. There is a large nut holding the fuel line onto it. Make sure you release the fuel pressure first or you can end having it spray all over you or the car/engine.

SOURCE: how to replace fuel pressure regulator on 1999 buick 3.1 v6

There not bad to replace, but you do have to have a special tool to unhook the fuel lines to it. And there should be just one set of wires goin to it also. It should take you about 20 minutes to change. If you have the right tools to do it.

Overreving with no power and excessive gas consumption air filter cleaned map sensor replaced fuel pump and filter


usually caused by busted diaphram in fuel pressure regulator allowing fuel to be drawn thru regulator directly to intake manifold. Pull vacuum line off regulator, plug line with golf tee, start car and watch to see if gas comes out of regulator. If yes, turn off car, replace regulator. The regulator sits near the fuel rail on the top of the engine as shown below. I will paste replacement instructions below from autozone.com in case you need to replace the regulator. Please let me know if you have any questions.

How to change a fuel pressure regulator in a 1997 pontiac grand prix


GM Century/Lumina/Grand Prix/Intrigue 1997-2000
Fuel Pressure Regulator - Removal & Installing

The fuel pressure regulator is a diaphragm-operated relief valve with fuel pump pressure on one side and regulator spring pressure and intake manifold vacuum on the other side. The regulator's function is to maintain a constant fuel pressure across the injectors at all times. The pressure regulator compensates for engine load by increasing fuel pressure as engine vacuum drops.

The fuel pressure regulator is serviced as a separate component. When servicing the pressure regulator, make sure that the O-ring back-up, large O-ring, filter screen and small O-ring are properly positioned on the pressure regulator.


44dcbf8.jpg Fig. Cutaway view of a typical fuel pressure regulator


REMOVAL & INSTALLATION
The need to work as cleanly as possible cannot be over-emphasized. Even the smallest amount of dirt, if allowed into the fuel pressure regulator and/or the fuel rail, will find its way to the fuel injectors. The nozzle openings of the injectors are very small. Keep hands and tools clean. Clean the areas to be disconnected with a suitable solvent. Carefully cover open fittings and connections to keep out foreign material. Dirt in the injectors almost guarantees a clogged fuel injector and engine performance problems.
3.1L and 3.4L (VIN E) Engines
  1. Disconnect the negative battery cable.
  2. Relieve the fuel system pressure using the procedures found in this section.
  3. Remove the upper intake manifold assembly. Please see .
  4. Disconnect the vacuum line from the pressure regulator.
  5. Remove the regulator retaining screw and remove the retainer bracket. Using a clean shop cloth to catch fuel spillage, carefully pull the regulator from the fuel rail. Twist the regulator slightly while removing to ease removal. Discard the O-ring.

Fig. Exploded view of the fuel pressure regulator mounting-3.1L and 3.4L (VIN E) engines
To install:
  1. Clean all parts well. DO NOT use shop compressed air to test or clean a fuel pressure regulator. Clean the fuel pressure regulator screen, if necessary. DO NOT immerse the fuel pressure regulator in a solvent bath or it will be damaged.
  2. If the filter screen has been contaminated, it should be removed and the pressure regulator replaced.
  3. Lubricate a new pressure regulator O-ring with clean engine oil and install on the regulator inlet.
  4. Install the fuel return pipe to the regulator.
  5. Install a new retainer and spacer bracket into the slot on the fuel rail and install the pressure regulator to the fuel rail. Tighten the fuel return line nut to 13 ft. lbs. (17 Nm).
  6. Connect the vacuum line to the pressure regulator and install the retainer screw. Tighten to 76 inch lbs. (8.5 Nm).
  7. Inspect and verify that the retainer and spacer bracket is engaged in the slots in the fuel rail. Grasp and pull on the regulator to ensure that it is properly seated.
  8. Install the upper intake manifold. Please see .
  9. Connect the negative battery cable.
  10. Inspect for leaks using the following procedure:
    • Turn the ignition switch to the ON position for 2 seconds.
    • Turn the ignition switch to the OFF position for 10 seconds.
    • Turn the ignition switch to the ON position again.
    • Inspect all areas for fuel leaks.

Other size engine can find in autozone.com (free register).
