The only thing i can tell you is to get all the gas you can out of the tank, even if it means droping the tank. Then blow out the fuel line, install new filter, fill up with new gas with a fuel additive that cleans injectors and run it. I believe the worst that can happen is clog up the injectors, witch may not happen if you just run it. Depending on how much sugar was put in it.
You need to thouroghly drain all fuel for the fuel system by removing the tank and cleaning it, check and clean the fuel pump filter (sock), replace the fuel filter, bleed new fuel through the fuel lines to ensure that no sugared fuel is in the fuel rail. It is most important that you do not start and run the engine until this has been done, the sugar in the fuel will carmelize inside the engine and cause your intake valves to become stuck, causing misfire and valve burning, it will damage the engine.

This is one of the greatest urban myths. Sugar in fact does not dissolve in or combine with petrol, so it will lay in the bottom of the tank.
However if there is a large amount of sugar it may clog up the filters, so it is best to get it mostly out. If the tank has a drain plug it is easy, just remove that, catch all the fuel, let the sugar settle out, replace the plug, pour in the clean fuel above the sugar, and repeat all the procedure once or twice.
If there is not a drain plug the tank will have to be dropped out, which is not a hard job for a mechanic with a hoist. This is also a good opportunity to check and clean the filter on the fuel pump, which is mounted on the tank.
Then lastly if you get any signs of trouble, replace the in-line fuel filter in the engine bay.
Sugar has been dismissed as a vandalism method for cars. There is no affect to the engine. It just sits in the tank and the fuel system is protected by a screen. So the issue that you are having has nothing to do with the sugar. Take it back to the mechanic and tell them to fix it because they probably did something.
do you know how much ? you can sometimes get away with it in the fuel system if you add some additives or higher grade fuel. but if your not to sure how much was put in its best to empty the tank. sugar in the fuel can block the fuel lines and injectors before even hitting the plugs so would go with emptying the tank but it is up to you. somtimes the filter can deal with the sugar but to muck it will just cut througe the filter.
drain tank and flush clean asap! change filters make sure all traces of sugar are removed from fuel system, this will destroy a motor quickly if left unattended.
First off it is a myth that sugar will destroy an engine. Sugar will not dissolve in gasoline. Depending on how much sugar was added it could clog the fuel pump sock filter. You have drained the tank, so add 5 gallons of fuel to the tank and start the engine. It will do no harm whatsoever. You may have to change the fuel filter a few times if the sugar clogs it but otherwise no harm will be done.
remove the gas tank and wash it out with gasoline or another solvent. Replace fuel filter/s. IF sugar got past the filter; Disconnect the fuel rails from the injectors, and clear the fuel lines. Remove your heads and clean the heads and each cylinder, because supposedly the sugar, if it gets that far, will carmelize and can seize up the motor.
if it still starts then your ok.remove gas tank and dump fuel.clean out any sugar on bottom of tank.go throuh the fuel pump hole. use a water hose if needed then let it dry.fill up tank and just run it it will be ok. what sugar does to an engine [and never mind myth busters, they are wrong] ive seen it 4 times, someone in town was having fun with sugar in the tank.anyways with enough sugar in gas tank the sugar disolves in the fuel.then engine,especially the valve stems get hot and sugar becomes a molten goo on the parts,valves,pistons,cylinders,fuel injectors.only the hot parts seem to be effected. then when you turn the engine off the sugar cools and becomes hard like a piece of hard candie.the valve stems are now locked into valve guides and cannot open or close,it takes alot more driving to damage pistons and rings only a little sugar is injected on every intake stroke and its aimed right at the valve stem.one mile of driving i dought will cause problems. beware that if the sugar was poured it dry you will need to flush out the filler neck.if it was dry then very little got in the tank anyway,unless you put gas in it after sugar was added
It is a myth that sugar will mess your car up. Sugar does not dissolve in gas, it will just sit in the bottom of the gas tank. You will need to drop the tank and have it cleaned, and replace the in-tank fuel filter, but anything upstream of the fuel filter will be okay.
you need too flush the tank what that prob is
is pices of the old fuel pump that thas broke off or pellets where thy didnt trim the plastic piece that sits in the bottom of the tank
if it was sugar ,it wouldn ball up like that ,sugar doesnt do any damage till the heat of the engine hits it
