Sometimes the starter motor turns the engine for 4 or 5 seconds before starting.
If i stop it after 2 seconds or so the then restart it its ok
Any ideas ?

 

Is this happening only the first cold start in the morning or even during the day with warm engine? I had a simular issue but only in winter months and about ones a week, it would start fine always on second try right a way like nothing ever happened.
After installing new CPS (crankshaft position sensor) I never had this problem since, for 2 years (27K miles). This was just my own experience, some other members may have a differnt opinion on your issue.

 

Thanx for that, it seems when hot.
