Have a gas stove and all the burners light except one what would the cause be?
Knowledge comes with experience
Simple question, simple answer. Either no air, no fuel or no source of ignition.
Next time try not to overwhelm us with information.
Where are you? Are you done yet? I got ONE more call for you.....
Can you light that burner with a match? If so then check whatever lights the burner. is it a spark ignitor ( is it dirty or broken or disconnected) or is it a pilot light tube ( connected and not plugged with junk).
I like to call it spillage. Pot boiling over clogs gas ports. Clean them out
