Question
have read about your starting problem, thought i would share mine with you. had the car serviced and two weeks later i went down a motorway and the car engine just died. after about two minutes it finally fired up ,so i got home.tried it one minute after getting home and it would not start. tried again later and all i got was the key code light staying on and the car would not start.this happened many times and then the light went off, great i thought now it will start , but no, just turning over again .a garage has got the car and they have been trying it , but the same happens there , some times it will fire up but later cut out and some times it just turns over , sometimes key code light on others not . UNBELIEVABLY FRUSTRATING . any ideas as to how to solve this problem, it will save a mans sanity!      Thank's  Garry .

Answer
It is probably either the ignition module or the fuel pump. And it may be shut down by the security system. Next time it happens be prepared to remove a spark plug. If it is wet then the ignition module is suspect--if it is dry then the fuel pump is suspect. But, first try to disable the security system.
