Hello, straight to the issue. Tried to do a compression test as had misfire in #8.
now no fuel and no start. Turns over fine and there is spark. I’ve tripped something in the computer no pressure at the fuel rails on the motor no door lock function (odd) just will not start. Lots of battery power as well.

If you haven't already try posting you question in the XJ8 forum. You'll probably get more responses.

 

Well it seems it’s a bad fuel pump, it was cutting in and out confusing the issue. Made me think that disconnecting the igniters caused some computer issue. As it would work then I would move things around to diagnose and it wouldn’t ,,,
love this car!
