motor won't crank over now

[variationperson]

I was working on my cousin 72 chevy truck ,at first it wasn't getting gas from the tank,so I pulled the gasoline off going to the tank and put a gas can to get gas,then the motor stopped cranking over.I ran news wires just like the digram that was showed on here .purple went to the starter,light purple/orange change to the yellow wire,so yellow went to dist,and the other yellow went to the other side of the starter. I put a new ignition switch in it but i am not getting any power to the purple wire going to the starter .could it be the fuse panel ? lmk thanks
