Guess it's the same world 'round?

Try the circuit (for testing purposes only) without the GFI and test for current.

No current.... Try a new GFI.

If all else fails, cut the power, grab the wire and aggressively rip it out of the ground. This will loosen the soil plenty for its replacement. (Without the casual labor)
