I have a 2000 chevy z71 4x4 pick-up truck. a few months ago i had problems
getting it to start. a few hours later it started fine. i replaced the
battery about a month ago and now it has done it again. when trying to
start it up it would just give a continous clicking noise, leading me to
think it was my starter. now when key is turned (not trying to start it
up) it makes the same clicking noise and worse when i hit any of my power
accessories.  Please help me out. thanks.
