As Mark said above check your plenum and check that the ECU hasn't been flooded.
Is the under bonnet fuel pump running when you turn on the ignition, if it's a Facelift model then check for fuel flow at the filter head by putting the inlet pipe into a suitable container.
If the fuel pump is not supplying fuel then the ECU is a likely suspect.
If this is the case send me a message and I can test it for you and possibly repair it if needed. If it is beyond repair then I do stock replacement ECU's
