Hello guys,
i have this car starting problem when engine warm up,no dtc in ecu,it only start when engine is cool.
the car driving very well not cutting off on road.
i'm thinking maybe something wrong in MAP.
I noticed that the fan run around 97degrees in low speed and cut around 3-5 seconds.
Hope someone could help me to check the MAP

VIN:SJNJCAJ10U7015484.

Year:2010
ECU:Continental,SID303-S180033108 A.

I dont understand why you read ecu and post files.
There is no such a think as "worm start off" problem.

Crank/rpm sensor? pretty common on Alfa/Fiat engines.

No dtc,change crankshaft sensor without success,all injectors are ok,
Note that the engine is making too much smoke when driving.
Maybe something wrong with engine?
Any idea??

Have you checked the diesel pump?

Maybe timing belt error

Connect consult 3 plus and select engine data monitor.
Monitor the voltage fluctuation in battery volts.
My experience its should be an alternator problem.

The phenomenon may be like this.

After warm up.
Acceleration time working ok,
but while decelerating or reducing the vehicle speed or idling the engine may be will cut off....
