The fuel pressure regulator is part of the fuel pump assembly. To replace this, you need to replace the fuel pump assembly. There is a plate under the rear seat that will give you access to the pump assembly. It is an easy replacement. I attached a picture of the pump. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

The fuel pressure regulator on this vehicle is actually in the tank as part of the pump assembly.

One way to test this is to check the pressure so I am attaching the info on how to check the pressure but here is a guide that will help with this.

Below you will find the location and process from the manual on how to check this as well.

Please let us know if you have other questions. Thanks

The pressure regulator for that vehicle is built into the fuel pump assembly, inside the fuel tank.

Fuel pressure gauge. If the regulator is on the engine and has a vacuum hose going to it, pressure should go up when that hose is disconnected. Pressure regulators cause a lot of trouble on General Motors cars and trucks, not on other brands.
