One of the burners on my gas stove won’t light and it emitted gas with a sulfur like smell - does that mean I should replace the entire stove?

I love to cook, so I purchased a gas stove in order to have more precise heating when cooking, but now I’m worried about the safety of gas stoves. I’m using the other burners that work, but I’m afraid the other burners might be emitting gas too. I plan on doing a carbon monoxide test tonight.

I need some advice. Do you think it’s worth getting an electric stove, just so I don’t have to worry about carbon monoxide poisoning? Thanks.
