When sugar is put in gas it turns into a thick slim. Some of it will normally make it through the fuel system before the sock filter on the fuel pump clogs. This will happen pretty fast if enough is put in the tank. Most of the time it will only ruin the fuel pump and fuel filter, but I have seen it clog the fuel injectors, and even damage the pistons. We usually replace the fuel pump and filter and flush the gas tank and gas lines. Then get it running and see what else is damaged.
I'm sorry, but I thought it had been done to you. This site is not made to help people do such things as this.
