GOOD NEWS!!! I disconnected the big wire from the starter motor (the one that runs into the auxiliary jumping point, AKA the little red box next to the upper radiator hose) and left the purple smaller wire connected. I turned the key to start and I heard a single CLICK. And it wasn’t the fuse!!!!!! So now that I’ve gotten it down to that, do yall think it’s the solenoid or the starter itself? Thanks so much for yall’s help.
