You might try changing your crank tooth setting on your initial data load. Mopar did some teeth changing mid year. I don’t remember now what year your Hemi is but if crank tooth is set wrong on data load the motor will give absolutely every indication it will start but won’t. Ask me how I know.
Well its a 32tooth setup and supposedly this computer is the has the correct setting for this setup BUT I can't get the damn thing to talk to my obd2 reader at the moment... ugh
