4WD Service Light

I dropped my fuel tank to replace the fuel pump and also replaced the fuel filter yesterday. I removed the 4 bolts from the drive shaft in the back to make more room for work but they went back in fine. (just for context) On my way back, the 4Lo light flashed once but nothing else. This afternoon I started the truck and the 4WD Service light is on and the truck won’t go into 4wd. The turning is also a little funny now, but I don’t know how to explain what it’s doing. What could have caused this/what may be wrong.

It feels funny in turns because the 4wD is engaged and it’s crabbing.

Get it repaired before operating much on asphalt or you may destroy the transfer case.

Manual 4x4 lever, or electric switch?

Electric switch. Is there something within the process of that fuel pump swap that may have caused it?

May have pinched the wiring harness above the tank? Easy to do in most vehicles.
