hot on

I have a Fiat Siena 1999 Motor 1300 passes that when I light it in cold in the morning I turn on at once, but when the engine is hot, I turn it off and it costs to turn on what this can be I thank who can help me I am D Venezuela

In that brand I have no experience but if it serves something, the Nissan have that problem to such a degree that sometimes they do not light hot when it is disconnected or the coolant temperature sensor does not work. But you will have to check if the cylinder head is not burned sometimes it costs to start an engine when the packaging is burned between the cylinders.

Command to check the starter engine

I agree with the partner, check the engine coolant temperature sensor, since if the connection or the sensor itself fails, the switchboard believes that it is "permanently cold" in such a way that when you start it in the morning there is no problem, but hot drowning due to excess gasoline.

You will notice it for a strong smell of gasoline in the exhaust when you try to start hot and because the consumption of the car has increased since the piece was broken (the switchboard continues to think that the engine is cold)
