HELP Car will not Crank over (STARTER?)

ive been having trouble with my starter for awhile now…it used to hear the starter click and after a few trys it would start…a few days later…it would just click and never start on its own…now it just doesnt click at all…so i fugred it was my starter…i just got a new one and put it in…still nothing…will not crank over and no click again from the new starter…

fuses are still good
could this be an electrical problem
or is my ignition switch busted somehow?
or should i just get a START push button?

anyone know the colors of th electrical or have a diagram for the wires for the ignition
