try resetting your security system if no manual look online. because the battery was probably disconnected causes this to happen.

I ,m having a hard time finding something on resetting security system. Could this cause no fuel pressure on fuel rail.

yes it will. I found this on the jaguar forum which I would advise you going to as well and joining.
I unplugged the Security Module behind the glove box, and blew off the connections, plugged it back in, checked fuse #5 and #7 in fuse box below rear seat on driver side and the car came back to life. No towing to dealer this time, YAYYYY! The crazy warning saying HOOD OPEN went away too! Trunk back to working normal. The only problem still having is with windows. I'll report back the fix when I get done. the power windows may not work either if you do this so will need to be reset otherwise you'll have to take to a dealer.
