Starting issues - 92 xp help and restoration

[lobsterdeli]

Having trouble starting. took starter out and tested works fine. When i press the button it just clicks. I suspect i have some kind of issue with my ground but unsure. theres this clump of wires in my Electrical box that goes to ground that i think is the problem. does anyone know what it is?

has a aftermarket mpem that i think may be wired wrong still figuiring that out aswell. the weird thing is it just randomly wouldnt start, it also has a parasitic draw that i think may be related.
