For the 1128/1130 codes, check the oil filler tube, oil fill cap and dipstick O-ring to make sure there are no air leaks.
Both of those codes are caused by an air leak.
As MarcW said, check Fuse E6.
Also, there's a vent line that runs from the evap canister to the throttle body.
Pinch the line at the throttle body and see if you can now put gas in the tank.
Happy Boxstering,
