The electric pump is attached to the fuel sending unit, located in the fuel tank.
Using the GM fuel gauge sending unit retaining cam tool No. J-24187, J-36608 (or equivalent) or a brass drift and a hammer, remove the cam locking ring (fuel sending unit) by twisting counterclockwise. With the locking ring released, carefully lift the sending unit from the fuel tank.
Remove the fuel pump from the fuel sending unit, by performing the following procedures:
When removing the fuel pump from the sending unit, be careful not to damage the rubber insulator and the strainer.
When installing the sending unit, be careful not to fold or twist the fuel strainer or it may restrict the fuel flow.
A brass drift and a hammer can be used to loosen the fuel pump locking cam

Check your fuel pressure at the Shredder valve, you should have 60PSI to 65PSI. If you have less then that or more then that your going to have problems with your fuel injection system. The other thing to is to check your fuel pressure regulator. Hook up the fuel pressure gauge and turn the ignition switch to the run position to activate the fuel pump. Once the pump stops pressurizing the fuel line wait and see if your losing the fuel pressure excessively. If you are then your may have a bad regulator and it's leaking internally. The other thing to is may be a bad fuel pump, The good news is the fuel pump in the sending unit in your bravada can be replaced rather then the whole unit. If it is the fuel pump, Buy a heavy duty pump to install to your sending unit. Don't have them sell you the whole unit, pump alone is around average $60.00 other then the whole unit for $230.00. Good luck and keep me posted, be glad to help

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 .
