Discovery 3 Cranks but does not start or Starts and Cuts immidiately

We will have to wait about six months from now, then we have a cut from rainy ****ty 7° to about 40°C for a week and thats our summer here xD They are all dry unfortunately. Is this a common problem that my car has? Has anybode had this yet?

Thanks guys!

So, she is back at live, i bought another D3 with an engine jam and swapped all the electronics, so i guess the engine ECU is toast. Now she runs great again.
