The fuel injection pressure regulator maintains consistent fuel pressure at the injector rail, ensuring accurate fuel metering regardless of engine load and RPM. Signs of failure include: a check engine light with fuel pressure codes, a rich or lean running condition, rough idle, hard starting, or fuel pressure that is too high or too low when tested. Replace a failed regulator to restore proper fuel system pressure and accurate fuel delivery.
