There is a fuel injector relay, but I'm not sure where it is on the XJ8. Someone should be along shortly with the location. You can swap it with another relay of the same color.

If you have a friend to help, do this.
Open the boot, remove the back panel (2 clips securing), this exposes the fuel tank. Someone can stand in the trunk and start kicking the tank. When the tank is being kicked, crank the car. If it starts for 2-3 seconds and then shuts off, you have a bad fuel pump.
