On my 95 gt, I've replaced my starter, brand new battery(*13.1v and has passed a crank apms test*), ignition switch replaced, tested every fuse and relay, all fine. My ignition, (*sometimes*) will allow all my lights on at the on position, but when I crank it, there's a slight tick then I lose all power. The s pin gets disconnected from the ignition, I don't lose power but starter doesn't engage. Any idea, I think bad ground but idk where they are or how to fix it.
