2003 Maxima won't run with crank sensor plugged in

I have a 2K3 6 speed, I just replaced the engine, at first I kept getting the p0335 code, but the car would take a long time to start but eventually it would start and run strong. I realized the reason for the code is I mixed up the sockets for the Crank Position with the O2 sensor. After correcting the crossing the car will now start right up but idle like hell for a few seconds and die, I tried pressing the accelerator and that doesn't help. I have an OBD2 scanner and I checked the readings from all the sensors and everything seems to be responding ok. Any ideas? I went through the, Accelerator Pedal Release Position Learning Procedure for 2K2+ and the Throttle Valve Closed Position Learning Procedure for 2K2+ still with no luck, any suggestions on where to go from here? If I unplug the crank sensor it runs fine just takes a while to start.

Thanks everyone for your help.

I'm sorry I should've left this in my original post, the sensor is brand new but I'll retest it.

Try to start the car up and read the live data and try to capture it and repost your findings

Quit throwing parts to it-check the crankshaft sensor's wiring back to the computer for short/open if okay could be the computer itself have it further checked
