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

check the neutral safety switch. If an auto trans, it is in park or neutral? Don't laugh, I've done it.

The ignition switch gets its power from the fuse block. I bet you’ve got a dirty or corroded contact in there. I dealt with this on my truck. I don’t remember the specifics but I lost my ignition switch, backup lights and a few others. My K20 is a 4 speed and doesn’t have a neutral safety switch.
