Hi, does the engine check light flash, is would indicate a immobiliser fault. The hand book says "turn key to position O wait 2 seconds then try to start. Failing that you could check the Calibraclub net, go to search, put in immobiliser and there is 11 posts on problems. Page 7 and 8 maybe of help and they mention fuse 11 also the immobiliser unit which they say holds 2 relays soldered to the printed circuit board. They say the unit is behind the passenger foot well.
Hope it helps
