Infiniti Repair Questions? Ask a Mechanic for Answers ASAP
The can sensor will not prevent the car from cranking or starting. It sounds like you just had a bad battery or bad battery connection.
Do you want some help changing the cam sensor if it is indeed faulty?
The cam sensor will never prevent it from cranking. It might make it crank but not start. The only things that keep it from cranking is battery voltage, bad starter, or a bad relay, but the relay won't fix it self. If it's bad, disconnecting the battery and hooking it back up won't help.
I would closely inspect the battery cables and terminals and make sure the wires aren't frayed, broken, or corroded. Infinity will rarely give the low voltage click, it usually just clicks once and looses connection if there is high resistance between the battery and one of the cables. You should also check the ground wire from the negative post to make sure it hasn't come loose on the opposite side.
Let me know if you need additional information. I would love to help if you still need assistance.
