I think I may know the culprit, same thing happened with mine. I just posted this to a different thread here on the forum, and it may apply to you too.
Try this, when ever trying to start, turn key to MAR first & all the warning lights come on, in the centre MFD in the bottom right corner the yellow CODE light comes on with all the others, it SHOULD THEN GO OUT almost instantly, while all the others stay on. You can then turn the key to start & it will start no problem. If it stays on with the rest, you have an intermittent fault with the immobiliser and you can crank till the battery goes flat & she won't fire.
It is SO easy to miss as all the warning lights come on when starting and people RARELY notice that the CODE light is staying on with all the others, because the brain expects a fault to show by a light staying on when the car starts. But seeing the car won't start, ALL the other warning lights stay on too so you don't notice that the code light has not gone out unless you are looking for it too.
This had me going round the twist for days till I realised my brain was tricking itself.
Let me know if my crystal ball is right or needs replacing.
