Does sound like you need a new master cylinder. On a 2000 you wont need to back bleed. You will just need to follow the instruction and bleed the master and all four points. you will probably need to bleed the ABS block and proportioning valve but only if they have bleeders on them.

SOURCE: cant bleed out brakes
It takes time, do you know the sequence to bleed the brakes? Most cars r different. And you have to keep pouring brake fluid, That is a two person job. Make sure all lines r connected to MC and not leaking. After a while if nothing comes out MC could be diffective.

you may have a ABS problem. I would drive it and attemp to skid the tires an dsee if the pump activates. sometimes this will unstick any valves inside the ABS unit. you may need to have a qualified repair shop check deeper. the ABS will have a code, and a scanner will be needed to check further.
