The ECM is most likely faulty, i.e. fuel drivers. It can be rebuilt or get a used one from salvage yard. It may have to be configured by a shop which has the auto-logic software. Approx 3 to 5 hundred to fix for good.
hi i have been told by jaguar that xj8 up to 2000 had nickel lined engines . the nickel wears and causes flooding. he told me to sell it and get a 2001 onwards as these wher steel lined which stops the flooding problem hope this helps.
