If the fuel rail sensor stops working will that stop fuel production?

If the fuel rail sensor stops working, it won't directly stop fuel production, but it can disrupt the engine's fuel management system. The sensor monitors the pressure in the fuel rail and provides data to the engine control unit (ECU) to optimize fuel delivery. If the sensor fails, the ECU may not adjust fuel flow correctly, leading to issues like poor engine performance, stalling, or reduced efficiency. However, fuel can still be delivered to the engine, albeit potentially inappropriately.
