the car looked like it was about to crank out

what does this mean?

first thing to do is stop at an autozone or similar and ask them to test your OBD port for any trouble codes. you probably have one or two.

could not fully understand your post but some things that could be an issue are:

BCM
petrol pump
nissan vehicle immobilizer system
key cylinder
IPDM
cam position sensor

getting the codes checked is the first line of defense.
