replaced throttle position sensor. car will not start

I believe there are "relearn" procedures involved in servicing your car. Also, I'm suspicious that you have another problem in the engine control system and you may not have gotten a complete diagnosis. It sounds like you replaced the throttle position sensor without relearning and maybe that's not even the problem. Tow the car to a Nissan specialist and get it diagnosed right and go from there.
