I have a 03 6 speed 350Z touring with 120,xxx miles. My car will not start. It'll just crank and crank. We tried to bump start it and it fired right up. It is throwing the following codes, P1706-Park and Neutral Position Switch, P1121-Electronic Throttle Control Actuator, P1122-Electric Throtle Control Performance Problem, P0327- Knock Sensor Low Imput Bank 1, P0462- Fuel level Sensor. When we bump started my car, it rev'd fine, idled fine and acted like nothing was wrong. It just WILL NOT start with my keys, it'll just crank. Also, once we bump started it it ran perfect until it was all warmed up. Whenever I were to push in the clutch it would die. Once it's warm it will not idle.
