I wrecked the truck on the passenger side front and back the electronics quit working now I'm trying to bring it back from the dead I was told a crankshaft positioning sensor but mine is fine dose anyone else know what it could be

 

It can only be the crank position sensor, but I guess it could be a wiring gremlin, how did you determine your VSS is good (its actually called vehicle speed sensor)

 

I replaced it with a new one from koi I got the charging to work its just overdrive and the speedometer now

 

On my ramcharger I bungled up reinstalling the speedo on the tcase after changing the output seal. I ended up with the same problem.
