Hi all thanks for the input. I have now got the car started and it runs ok. However for all you GDI owners this is what I did. I checked for a spark(it had a good one) so took off air filter plate and took out air filter squirted some easy start in,and tried to start it, it nearly fired,so took off the intake pipe nearer the engine and squirted more easy start,this time it fired with foot right down on the accelerater as if choked,and it fired up and ran.So if any body can explain why a GDI engine can be choked when not going through the correct starting procedure I would love to know. Good job it did it at home where I have the facilities to sort it ,many thanks duncan
