Need some help please. 2004 350z touring auto 162k. It will crank but won't start. Brand new battery. NATS light turn off when I put the key in. I dont really hear the pump prime but I did spray starting fluid but no luck. Cel is on when I put the key in on position. So it is reading the ecu but then when I put a code reader to read code it says it has no communication. I am at totally lost on what to do next.

 

tell us when the last time you replaced the cam shaft and crank shaft position sensors with OEM or Hitachi-brand sensors?

 

I haven't replace them. But would the sensor cause no communication when trying to read codes?
Thank you
