cant remember name of Kids tv show?

[Senjo Limbu]

Does anyone remember a kids TV show back in 2002(the show it self may be much older) it was to do with this skinny guy who seems to me like he was traveling through different periods of time. at one point he stops some Incas/may be Mayans from sacrificing a girl to bring back the sun;and this other time he's in a western period and he prevents these red-necks from killing a Chinese guy. it was really confusing.
I would really appreciate it if someone could help me out with this before I loose my sanity.
thanks

further information
used to be played on channel 5 Sunday morning I think.
Please don't tell me to look it up on the list of past shows presented on channel 5, I have just spent nearly an hour staring at list from a*bc,channel 5, milkshake, bbc, and some Aussie network that I haven't even heard about.
thanks again

maybe it was the show QUANTUM LEAP. it was about a guy who would "leap" through time saving people hoping the next jump would send him home
