Coil issues wouldn't explain the white smoke and poor running.

Where is that fuel coming from? Scary. Take care of that, first.

Check your float level by removing the site plugs. If fuel comes pouring out, that will be your first indicator.

White smoke sounds like coolant to me...

On the coil, check it when it fails. After you resolve the fuel issues drive it around until the car dies, THEN test the coil.
