1996 xj6 jaguar wont start batt is new the motor turns but wont start

Need to check for fuel and spark
You can crack the fuel line connector at the back of the rail on the drivers side to see if you are getting fuel or have someone listen in the trunk for a humming/buzzing sound when you first turn the ignition on, if you do hear this then the fuel pump is probably working so it would be the crank sensor that has failed. If you have 1/4 or less of a tank of gas, check to make sure you actually have gas as these cars have faulty fuel sendor units which will stick on a 1/4 of a tank.

Check the fuses and relays on ur jaguar. also check the ignition system.
