There are multiple FUSES that are incorporated within the crank / start circuit .. These will be located in the under hood fuse relay box .. IF fuse is blown - you’ll get the same symptoms .. Due to misleading fuse usage listing - I ‘strongly’ recommend TESTING each and every fuse you can find using a 12 volt test light.!

Also the park neutral switches are problematic on these vehicles - you should have a wiring schematic for the related circuits - which can be easily obtained from AutoZone’s web site..

Good luck!
