what would the sensors prevent the car from doing exactly??

Its not stuck in gear as im able to bump start the car no problem and runs all day untill you turn the car off..then you have to bump start the car again to start it.

Sounds like you can push start it? If that is what a "bump start" means. You need to test the connections from the ignition switch to the starter motor. You set a volt meter to 12 volts then connect the meter at the beginning and end of the signal path. If you find a voltage reading above .25 volt you have a bad connection in that circuit. Start at the battery positive cable and the starter power connection. Then work your way through the circuit if you get a voltage reading of over .25 volt which indicates a bad connection in that circuit.

My first guess would be a bad ground that is not letting enough power to the starter for it to work. This would allow you to push start the car but it would not start with the starter motor.

Another way to test it would be with a push button starter bypass switch, like mechanics use to move the engine around to check the valves. It goes from the postive battery terminal to the starter solenoid and bypasses the key operated ignition circuit. If it works this way you have a bad connection in the keyed ignition circuit. If not then it is more likely the ground circuit from the starter back to the battery,

sounds to me like your ignition switch is dead in the start position; one of two things can be done;

1. change out said ignition switch

2. wire in a start button

sounds like you found your problem already, but the computer will look for the cam sensor and crank sensor and make sure they are working before it allows the coils and injectors to get power. otherwise, the computer doesn't know how fast the engine is running.

I know this thread is old now, but just wanted to say I think baldlobo is right, I had a 2.2DI Sport+ and it was the ignition switch. Bought a new one from Nissan and replaced it myself. Fiddly job but do-able if you're fairly competent. The ignition switch is directly behind where you insert your key.
