since no scanner available at this time, because that is what you need
if the instrument cluster is out ,the antitheft module circuit goes thru it ,so if our cluster not working , the truck want start because the security system preventing it we can try reset it
the cluster could not be working for several reasons , wiring ,bcm module , cluster itself, rear connector of the cluster etc...
have you checked all fuses with a test light ?
