Fuel injector not working?

No I did not lose a key. This is not a coded key on this model. The strage thing on this for me is the security system on this vehicle would normally dissable the starting motor. But you made me realse that the security light should come off when the ignition is turn on but but it stays on thats why I dint think it was a security problem. I will put the X431 on it this afternoon and check it and no I didnt get any code. And the x431 is actually very good on nissans I personally beleive it can do any thing the consult 2 can do only last week I program a 2003 pathfinder key with out any problem. Thank you for your assistant any way and I apreciate your help and soon I as I can get this one sorted out I will sure make a donation. If u have any other ideas sure will love to hear.

Regards Andre.

Hi good morning I put the scan tool on and there is no code there isnt a option the do any thing with the security system with the scan tool but I follow the manual instruction the security light is still on when the ignition is on and even when u crank the engine.
