Busted grand scenic diesel will not stay running?

no engine managment lights on?heyho,first remove the fuel filler cap and run it in case the filler vent hole is blocked.next renew the fuel filter if u havent already.retry.next is engine code reader time.either u buy a code reader or get a garage to read it for you,but without valid codes from the ecu then you are guessing and wasting time/money.
