Hi! After winter started and drove for a moment. Then I shut down and restarted. Big bang, now no longer run. Sparks are black and gasoline smells. Whenever I start, explode and smoke. Corvette, c4, vm.84, crossfire

Just a guess. Maybe the timing chain.

The car starts normally after smoke but don't run. Bang and smoke but then as long as you turn the key, trying to start quite normally

Sounds like an injector stuck open to me. Pull the dipstick, does the oil smell of gas? If it does, stop trying to start it.

I vote timing issue, but could be fuel related.
