2016 toyota avalon
 

This is my first time here so I am hoping I can pose a question.
I bought a 2016 Camry LE 4 cylinder and its been the perfect car
Cleaned my battery terminals, and after replacing the cables several times, everything electronic worked
Later I noticed that with the engine off - keys in the ignition; it would crank but not fire. After 14+ times turning the key it finally fires??
Why? and how to fix?
I've already replaced the crank position sensor, didn't help.
Ideas?
Thank you
