Starter and fuel pump not working
 

Problem: No power to fuel pump or starter Knowledge: I can start the car arching the starter with a screwdriver, but i'm not getting any power to the fuel pump or starter with ignition.
Prior to (Very very little) overheating and parking, it ran just fine.
Backstory: So i had to replace a few hoses in the back of my engine (Good placement, BMW) which required me to take off the entire intake. (Again, fantastic placement..)
After finally getting everything put back together and getting all the wire harnesses in place, I am not getting any power to fuel pump or starter. but i cannot find the issue. The only solution i've been given, (Which sounds like total bull) is that it's because i currently have no water in the radiator.


I need some help figuring out this problem. any help is awesome!

Update...
 

So i swapped back to my stock stereo. After doing so, my dash board goes wonky when i try to crank.

You've got wires crossed somewhere.
