vauxhall zafira deisel turns over but won't start?

I had the same problem with mine, just cut out one day and wouldn't start. it had done around 100k miles at the time and it turned out to be the diesel pump, an expensive item to replace. eliminate air leaks first like replace the diesel overspill pipes if they are cracked they can allow air into the system and the car will need to be turned over for a while befor firing up
