Almost for sure a bad ground cable if it started smoking that quickly - and hopefully that was the reason it quit as well (low voltage). There is a chance that the motor doesn't want to turn due to some type of major failure, but generally it should be well more than 5 seconds of full amperage cranking through the starter before that occurs. It would be noce to see if you can turn the motor over by hand with a turning tool to confirm you don't have a motor issue, but DO NOT try to turn it over by the harmonic balancer bolt.
