Truck Won't Crank Over
I decided to take a look into trying to fix the little black wheel under the dash that adjusts the shifter pointer and realized while I was turning the black wheel that the plastic clip is broke on my 2001 F150 Super Crew 4x4. So when I went to start the truck up to see if anything changed it didn't want to crank. Lights, radio and all other accessories come on but nothing happens when I turn to crank the engine on. At first some of the instrument lights would come on. Went back under there to see if I could see anything that looked wrong but no luck. Now when I turn the key to the on position the only instrument light that comes on is the "ABS" on the bottom near the trip reset button. And when I turn the key to crank the engine the "ABS" light goes off. When I turn the key to crank the engine I don't hear anything under the hood or dash. Anyone have any idea what may have happened??? Battery is reading 12.5 volts. Tried connecting a obdii scanner to see if any codes were present but all I get is that it can't link up. I have no idea what is going on and need to get it fixed as soon as possible. Anyone know what is going on???

All I have to go on is pick out some areas that you present.
First, the ABS does not depend on the dash per sey but a separate module.
So that in it 'self is a clue to the rest of what you see.
When you go to cranking, the current to power the start solenoid and the starter is very much greater.
If the dash lamps are not on or go out at a cranking attempt, this tells you that voltage is not high enough to power the dash.
The cause can be the battery has an internal open, the cable connections are corroded, a connection is loose, a ground is poor at some location..
These faults amounts to a high resistance.
When this condition is present in a high current circuit, voltage is dropped across this high resistance leaving very little left to power other circuits
Bottom line is you need to start at the battery and go through all the cable connections, remove them, clean them and be sure each is a solid connection.
Once you eliminate these, you have narrowed the cause down if the issue is still present.
We can't tell you exactly where the issue is but what it likely is.
You have to run it down by process of elimination..
Be sure with a no crank that the transmission is either in Park or Neutral, or the start circuit will be open.
I know the shift position indicators break and mislead you for position until you catch on to it, so be sure where the shifter actually is and that the lever mounting bolts on the steering column tube are tight.
This all I can make out of it so some other issue could be present.
Good luck.
