Hooked up Kenmore Elite used DW replacing old unit that was connected to 12 gauge wire that has 3 lines shared. Dishwasher does not turn on. Is higher gauge needed ~if so what gauge? and to own circuit breaker?

12 is plenty big. i would take the 12 wire and run it to a surface mount box with a 110V outlet under the sink. then use a plug setup from the DW to plug into the outlet.
it should be a seperate circuit but unless it has a hot water booster in it, that is overkill.

The replacement DW is a previously used appliance?

What do you mean 3 wires shared?
A 12 gauge line is good for 20amps. Which is more then enough for a dishwasher.
Ideal the dishwasher should be on its own breaker. I would install a receptacle, then I would install an appliance cord on the dishwasher itself so that it can be plugged in. This way the dishwasher isn't "hardwired" and can be removed and unplugged easily to service or replace.
More info is needed on the share wire comment. You should have a black (hot), white (neutral), and a copper ground. If you have a red wire (2nd hot or traveler) then that line could have been used for other purposes.

The DW was bought via Craigslist appears in good condition but unknown if it had a previous problem... the wire that fed original DW is connected to another set of garage florecent lights then to the circuit breaker so line is shared that is line I used... sounds like own line to outlet or circuit breaker could be solution? Didn't know if new DW has heating element so needs more power?

Did it come with a warranty ? If you have 110V at the junction box underneath the dishwasher and it doesn't power up, then somethings wrong with the appliance.
