Help please - bike wont start

Aaarrrrgh. First problem I have had with my bike and its really annoying (I have to get the BUS to work )

I turn the key - the fuel pump whirs into life - the clocks light up and the dials go up and down, then the oil light stays on and there is no neutral light. I have checked the oil pressure switch (even replaced it with one from the Vauxhall dealers, it was cleaned the day before, but that was on Sunday and its defo dry (not that I wash it with lots of water or a power wash).

Any suggestions ? please! I'm on holiday next week and was planning away days.

PS tried Ducati Glasgow and they are so busy they cant look at it for a week and a half.
