Just swapped my motor from my wrecked 03 to my 05 Now I’m experiencing a no start issue the red NATS light is solid on dash,(when key is on)no sound of fuel pump and no fuel in the line. Is anybody good with these security systems I bought this car with a blown motor originally it had no security light when in the on position until the swap was done from my 03 plugged everything up and now I’m having this problem. I’m assuming the dude gave me a Bad key if anybody has any tips or fixes let me know please or I will have to take this to Nissan


Heres the difference in my Keys the black one is small and has barely and weight too it compared to my 03 key

PS my current key does not work for unlocking the door it fits in but can’t turn.

 

You purchased this Z on a wing and a prayer, but you usually get what you paid for. NATS issues usually take an experienced tech to figure out and it sounds like it's time you paid a good local one to work on this car.
