Try filling the pan with hot water and 1 cup of powdered dishwasher detergent. Bring to a boil on your stove, and simmer for 1/2 hour, watching that it does not boil dry. Add water if needed. Scrape the burned sugar with a spoon or other tool with an edge with the water still in the pan. A lot should come loose.
Dump the water, and scrub with cleanser and a scrubby. If what is left does not come off with scrubbing. repeat entire process. This has worked for me, and may work for you. The pan is unusable as is. The cheap detergent from the dollar store works fine for this if you don't have a dishwasher. Good luck with your pan.
