Default 1991 LS.. hissing noise from engine bay

Hey everyone.. earlier this morning i had to go drop my sister off somewhere and i noticed the ABS light was on.. a couple hours later mom woke me up telling me the car was hissing.. went up close to it and it was.. it sounds like there's some air leaking or something.. it's not the AC gas cause it's plug is all tight.. i think the ABS light and the hissing coming on at the same time isnt a coincidence.. also, the trac off just lights up and i can't push it back on.. several weeks ago i used to have the check engine light come up and the TRAC as well as trac off.. so could it also be that the traction going has caused ABS to mess up?
thanks what do you guys think this could be

well.. i pulled the wire going to the abs fuse.. disconnected it.. and now there's no more hissing and the ABS light is on as well as TRAC and Trac OFF.. so it def is related to ABS.. i'm gonna run a diagnosis myself.. it also killed my battery (which sucked to begin with) cause the abs pump was constantly running..
thanks for your help though
