2011 pathfinder wont start when cold

[robb67]

My pathfinder wont start when its cold out. It will start when its warm. Anything above 50 degrees.

I have a new battery and it cranks good, but no spark. coil packs where pulled and there is no spark. I changed the crank sensor and still will not start when it is cold. Fuel pump is working and it is getting fuel.

Any suggestions on this??

Thanks

going to sound crazy but check all your connections.. by check i dont mean look . take them off, clean them , replace and tighten
