lol yeah it's a bit of a PITA above the front driveshaft.

If it was replaced last year maybe it was mis-diagnosed and the wiring is the issue?? I've gotten XK's to start just by grabbing the harness and shaking it around; breaks enough corrosion free to get a good connection. Could be your starter was replaced but the harness was really the issue... and just the movement of the harness made it work for the past year.
