If the Smart Fortwo won't start, the most common problem is related to the crankshaft position sensor. This happens because the sensor mounted on the crankshaft of this car model is a type that has now been replaced by a more recent one. This newer sensor is equipped with an electronic board that allows for more precise detection compared to the previous one. Consequently, if you replace the original sensor of the Smart Fortwo with this newer sensor, you should be able to start the car. The video also illustrates the different functioning of the sensors.
