So I get in the truck this morning and it doesn't turn over or make a clicking sound trying to turn over. The lights, heat and come on but when I turn the key to start the parking brake light come on. It is engaged but I don't think it always lights up as I turn it on. Starter, Battery and alternator are new. I just drove it yesterday.

 

Loose or corroded connection at the battery or solenoid maybe?

 

It sounds like you should check connections at the battery at the least. Maybe enough juice getting through for a few lights but nothing else.

Start at the beginning and when you get to the end........................stop

That is NOT, I say again NOT a light to let you know the parking brake is set. There is NO light to tell you the parking brake is set. That is a brake system warning light, it comes in when the proportional valve AKA combination valve senses a LEAK in the system. Like you blow a brake line and the "pressure differential valve" AKA floating piston has moved to the low (leaking) side.

It should come on during start up as a self test, but then should quickly go out. Battery cables new? That can look good, but have internal corrosion. Did you multi-meter the battery?

 

Also, check your ground.
