Have turbo-pump engines ever been successfully started / re-ignited on the moon?

Both HLS and Blue Moon, at least from what i can find, both seem to use liquid chemical rocket engines driven by Methalox and Hydrolox respectively.
The plumbing required to run/start those engines is more complicated, and i'd imagine has more failure-points to take into account than the hypergolic engines used by the Apollo lander.

I was wondering if Hydro/Methalox turbo-pump engines ever have actually, successfully been tested on the moon before, because i can't find anything on it.

In the previous version i had a small legend of the stock antenna ranges in the bottom right corner, but i decided to exclude it because the numbers weren't correct-. Anyway, I hope it's accurate enough to be useful.
The online calcs used for determining antenna ranges seem to agree with it.
