Default car wont start!

so i just finished my ls6 intake and pp tb install and i took my car for a 5min drive and i noticed my speedo/tach/and a couple other gauges werent working but oil press was so i took it home and parked it, left for a couple hours, then came home to put it away and it wont start.

The radio and everything powers up when i turn the ignition on, but when i go to start it i get nothing, not even a click...so i put the jumper pack on it and still the same thing...my security light isnt flashing or anything..

So do you guys have any idea of what this could be or what i should check for?

thanks!!

Check the Cam position sensor, that would also explain the gauges not working properly. Your Rpm is determined from the CPS

Here is a picture of the sensor
