My Fiat punto 75 stalls when driving and the injection light turns on. I then turn the ignition key and the car starts as if nothing had happened. This failure takes place once a day or once a week, whenever it wants. I've changed the fuel pump and the position sensor, but it remains the same.
Finally, after changing spark plugs, air filter, fuel filter, coils, position sensor and fuel pump, the problem disappeared and it is now 4 months that I've been driving without any inconvenients.
