We have a problem with our black Fiat Cinquecento, 899cc, whereby it starts ok from cold, but only on the 2nd turn of the key, every time.
It will then randomly stall when warm, and not start AT ALL until cold. Could this be the water temp sensor reading wrong, and telling the ECU that the engine is cold, when it is hot, and putting it on the cold start / rich mixture setting, making it too rich to start when warm?
