Well I can tell you that my fog lights don't stay on when high beams are on.

I looked at that "jump more closely and it wasn't a "jump" at all. It is the power source to a small light used in most GM trucks. (it has a switch to turn it on/off and it is placed on a mount that clips the light into place)

Well, back to the DRL Module...
I replace it, checked all the fuses, opened the relays, and I found nothing wrong.
I hooked up the battery terminals and crossed my fingers...I put the key in and tried to turn the car on, but NOTHING happened AGAIN!!! I am getting no power to the gauges when the key is in the ON position. I can hear the fuel pump turn on and the injectors prime and I can also hear the relays in the fuse box click over, but I get nothing else from trying to turn on the car.
What could be causing this?

when my vats was the problem (GM ordered the wrong damn key) my gauges would work and everything would work fine. but the car wouldnt start and the column wouldnt unlock...
if the column unlocks then its not your vats thats freaking out...

If the VATS system is preventing the car from starting then the security light on the dash will be lit. The unlocking of the steering column is a mechanical function of the key and ignition cylinder and is unrelated to the VATS system.
There are any number of other reasons why your car might not start. For example, if it is an M6 then it isn't uncommon for the clutch safety switch to cause problems. If it is an A4 then the neutral safety switch could be the problem. The starter relay or the starter solenoid may be dead. Of course, it could be something as simple as the STRTR mini-fuse in junction block #2 under the hood on the left fenderwell. Those are the most likely culprits. It is also possible that the BCM isn't allowing the starter relay to ground but that is unlikely.

WhiteBird00, I talked to a local dealership tech. and he also told me to check the starter power wire, something about a fusible link.
I just haven't had any time to check it out. If it stops raining today, I'll check it after work.

Actually, there is no fusible link in the starter power wire. There is a fusible link in the ignition/starter relay circuit prior to the junction box but it is extremely unlikely that the fusible link would burn out without one of the smaller amperage fuses going first.

, but the car is at my parents house in Carrizo Springs, TX. 
That's like a 2.5 hour drive from New Braunfels, TX.
It won't have been that bad if I was in SA.

I offered him help and that pretty much sums it up. You trouble shoot your way and I trouble shoot my way. I work with electronics every day in the power industry so I would think I am pretty dam good with wiring and low voltage systems. Since DC systems are the most reliable systems in the world. And I work with them daily.
