The correctness of the regulator is determined on a running engine by the fuel pressure in the injector rail (see "Pressure in the Renault Logan gasoline system")

If the pressure is below normal, and the rest of the system is working, the regulator is faulty

It needs to be replaced as it is beyond repair.

The fuel pressure regulator is installed in the fuel pump module.
