CHEVY LOCATION OF FUEL PRESSURE REGULATOR

1999 Chevrolet Tahoe

Engine Mechanical problem
1999 Chevy Tahoe V8 Four Wheel Drive Automatic 150000 miles

Service Engine Soon indicator keeps flashing on my dashboard, took vehicle to have diagnostic testing and was told engine was misfiring, something wrong with spark plugs or wire set, changed but problem still exists. A friend recommends to change Fuel Pressure Regulator because spark plugs seem to be burned and this could be caused by air/fuel pressure not correct. Want to change this part but don't know location in order to replace. Please advise, thank you

Depend on which engine. 5.7 L it is under the upper intake plenum (black plastic cover). If you remove it, you will see the" spider" injector, the regulator is mounted on the side of the injector. If it is a 5.3L the reg is on the fuel rail on the drivers side. Check for fuel in the vacuum line to the intake manifold
