1. On petrol Nissan vehicles, if a problem exists within the Engine Management system, then key programming will be blocked.

2. If the immobiliser has been locked (incorrect PIN entry), disconnect battery and re-connect, then turn ignition on/off three times.

3. On later systems there is also an input from the Audio system, which if disconnected inhibits the starting of the vehicle.

Do you have any errors read?

Check Grounds, battery grounds are horrible on Nissans, check Injector resistance. Engine Wiring Harness could be at fault.

P.S. My problem with no start was due to bad PCM. Comm was OK but it had CAN problem and that is why I was not able to programm keys. Very frustrating but enlightening
