1995 Pontiac Grand Prix

Yes.

If you are going to do this yourself, you would remove the gas tank, clean it, replace the pump strainer. Remove supply line and filter blow compressed air to clean that line as well a return line from fuel rail. Install new fuel filter.

Remove fuel rail and remove injectors, if the filter got most of the sugar, you can clean fuel rail with compressed air (injectors removed).

Now the only problem is the injectors, look at top of injector, there is a small screen to filter objects, if you see the sugar at the injector opening, you may have to get the injectors cleaned (usually about $20 each at a fuel injection service shop).

Reinstall fuel rail, injectors, tank etc.

This is a big job, lot of work, but it can be done.

I would probably replace the fuel pump as additional insurance, but it MAY be OK.

Other options are get a used fuel rail and injectors at a junk yard, then clean everything before fuel rail, (tank, strainer, lines, filter).
