Re: Won't start when engine cold or stalled.
Tough one, its a petrol 2.5 is it?
An engine that stalls a lot is often the throttle body dirty, once cleaned and basic parameters set in the ECU it re-learns the correct idle.
It sounds as if the engine ECU isn't getting the correct signals to tell it what temperature it is and to 'turn on choke' as it would be in the oldern days'
Could it really be as simple as the water temperature sender that tells the ecu how cold or hot the engine is so it knows when to richen up the mixture? If the ecu is told the wrong info i.e its not being told its cold then that is a possible line of investigation...
Good luck!
Martyn

Re:
No worries,
That extra fault info change everything. If the ECU isn't recording a fault i.e error code when it does this? then the problem probably lies in a mechanical related part that happens to be electric, think ignition electrical switch, the starter inhibitor on the shifter stick, possibly even brake pedal switch.
Good luck, feed back what happens! this one is intriguing!

Re:
Thats a shame, well I wish you good luck with the dealer finding the fault for you. One thing to share with them that is prety important I think was what you said: "When engine stalls and cannot be restarted right away, there was no spark on spark plugs."
No spark at the plugs when stalled, thats pretty key...
Good luck,
Martyn
