Sounds like the trap in the sink is getting the water pulled out of it. It probably wasn't vented properly.

What causes sewer smell when air conditioner kicks on?

It could be that the condesate drain line has been connected to the wastewater/blackwater stack. The trap (hopefully installed) preventing sewer gas from moving up the condensate line may have dried out. If dry, sewer gasses are no longer blocked by the hydraulic seal... resulting in a nasty smell when the unit is turned on and the fan kicks in. Just a thought.

Can you be getting a sewer smell when you start a fire in the fireplace sounds crazy but when you start a fire and it begins to draw you can smell sewer?

Yes, my brother's house in CT. has the same issue and the cause is still undetermined. I initially thought that the house was so tight, that the fireplace "draw" was pulling the gas right thru the traps. That does not appear to be the case as the smell doesn't appear to be coming from the sink. He doesn't know of any vent inside the house, that could explain this. I'm going to suggest that he crack a door or window in the family room and see if that short circuits the draft and has any effect.
