How do you repair a hydraulic jack that fails to lift?

Assuming you have checked the hydraulic fluid and it's OK, you could look into replacing the seals on the compression cylinder, but with jacks as inexpensive as they are these days, it would be easier and maybe even cheaper to replace the jack. I routinely see two-ton jacks on sale at automotive stores for $20-30. just check the rubber seling at bucket's bottom of the ram and plunger they wear of.f
