My 05 Jaguar XJ8 won't start after a being in a car accident. I reset the fuel disconnect switch, but the car is still not starting. Will a low battery voltage prevent the car from starting? The engine turns over quick and sounds normal, but I am not getting any fuel pressure. Any ideas?

 

most modern vehicles today have an inertia switch that in the event of a collision will shut of the fuel pump and possibly other equipment.
dont know where yours is, could be sighted in the outside part of the footwells under a trim item.refer to manual
barry

 

It sound like you already reset the inertial switch. Go around to each fusebox and make sure none of the relays got jarred out of their sockets from the collision.
