Location of Fuel Injector Pressure Regulator in 1993 gmc jimmy?
The 1993 GMC Jimmy's fuel pressure regulator isn't a separate, easily identifiable component like in some fuel injection systems. Instead, it's integrated into the fuel rail itself. You won't find a stand-alone regulator. The regulator is built into the fuel rail's design near one of the injectors. To access it, you'll need to remove the fuel rail.
