The car will run (maybe not well) but when it is shut off and cools down the sugar residue will harden and lock up cylinders, valves, etc.
Sugar in the fuel tank might at best plug up the fuel filter or worse the fuel injectors, but won't lock up the cylinders, valves, etc as you have pointed out...

Anyone who uses a drill to drill thru a tank to steal fuel is beyond stupid.

Next we'll be hearing about lawsuits of a thief that received 3rd degree burns while under someone's car because he was trying to steal their fuel.
And of interest, that used cooking oil is now being stolen...interesting because a few short years ago the restaurants had to PAY to have used cooking oil hauled off. Now it appears it's like gold to them and their cashing in on it.
