2006 nissan Altima will not start cranking fine

2006 nissan Altima pulled in the drive 30 minutes later it will not start. Tested the fuel and very thing is good. It is not getting spark to the plugs. I pulled a coil and plug and cranked the car no spark. The check Engine light has not been on. The codereader showes no codes.

What should I look at next?

Check the power going to the ignition circuit and make sure that is ok. If that is good there then you need to see if the signal from the ECU is ok. If there is an ignitor in the circuit that may be causing the trouble.
