The engine turns over but won't start.

It was happy yesterday, its done this before. Last time I disconnected the battery and re connected it and it fired up. It's disconnected again and I'm leaving it for a while. Seems strange though that all other non start problems I've read about seem to be starter motor related but my engine turns over fine. It's like the immobiliser isn't letting me start the car. No spark at the plugs or something.

tdc sensor....can you hear the fuel pump wiz before it cranks? if yes - most likely tdc sensor as this doesn't give a fault code
