I have searched the threads, but so many ideas. After leaving the car over night (started the last few weeks) the car turns over, starts and then dies straight away. normally the third turn over, it splutters and splurts into life then settles down. From then on, every start is like all is ok and nothing was ever warm.

the car can be left all day and will still start first time, its just first thing in the morning.

Any ideas please

Just refreshing this question

 

Possible water ingress into one of the sensors maybe. Have you checked for any fault codes/does the ems light of the dash Illuminate after it does this?
