Fuel Pressure Regulator
The fuel pressure regulator is responsible for maintaining the correct fuel pressure required by the fuel injectors to properly operate the engine. On vehicles with a return-style fuel system, the pressure regulator is typically located on the fuel rails or injector pod near the injectors; returnless fuel systems will have it built into the fuel filter or the fuel sending unit / pump assembly.
When the fuel pressure regulator fails, it will result in a drop in pressure to the fuel system, while potentially sucking additional gas through the engine vacuum system. These issues can cause the engine to not start, poor driveability, and stumbling at idle.
