Land Rover Repair: 2002 discovery, mass air meter, crank sensor

Question
I shut car off the next day went to start and it just rolls over no start do you think it can be a crank sensor

Answer
Crank sensor failure is a possibility but it's nothing more than a guess.  Fuel pump, pump relay, mass air meter, or fuel injection relays are all equally likely possibilities, as is a security lockout on some models.  If you have spark at the plugs it's not a crank sensor.  If there is no spark it is a possibility.
