I was having the same issue as you at first and it ended up being the 140A fusible link on the positive terminal. I fixed problem and now the car comes on but it’s not reading a key at all. I can put my finger in the dash and it goes from lock to on but it won’t start for nothing . My Machanic who fixed the fusible link told me like “bro your car is on. Idk how but it’s reading that you don’t have a key and it’s powering on still.” So he mention that since it’s actually on , I could put the key in the slot and he can jump the starter wire to get it started .. paid him to $60 to give it a try & Now I’m in the car . It’s started . Been in here all day and I’m scared to turn it off or even take the key out of the slot because I tried it once and the car took a “crap” & cut straight off while I was double parked in the middle of the street. Luckily my mechanic didn’t get too far and he came back to jump it AGAIN for another $50! Now I’m still in the car and it’s 4am and idk what to do… do I just need to get the key reprogrammed? Could it be the bcm? I drove the car to a locksmith earlier and he said he had someone with a similar problem so he tried to make the new key or reprogram it or whatever and the bcm lost all connections & ability to connect or see any key at all so he had to get it towed to Infititi for whatever reason. I’m so lost. And I need my car but can’t stay in here and leave it running forever please help!!!

 

Any update on what you went though?

 

So bro just stayed in the car forever?

 

I’m having the same issue has anyone resolved this already replaced bcm ipdm and start button
