No crank/no start nightmare

Just bought truck so I do not know much about the history. When I bought it, it had a blown head gasket. I had it towed to my house. I replaced both head gaskets and all the rest of the gaskets above the heads. Got everything put back together, turn the key, and does not even get a click. I checked for power at the #30, #87, #85 terminals of my starter relay. I have 12 volts at these terminals. What I do not have is 12 volts in the start position, when I jump the #85, and #86 terminals of my starter relay. I took the cover off off the relay, and when its plugged in, I can close the contacts manually, and the engine will crank over. I can even get it to run if I prime it first. I checked for 12 volts at the crank fuse, okay. I checked for 12 volts at the purple wire at the park/neutral switch in the start position, okay. I manually jumped the purple to the purple with white stripe wires at the park/neutral switch, nothing happens. I checked for continuity on the purple with white stripe wire from the park/neutral switch to the #87 terminal on the starter relay, okay. That is where I am at now. What do I check next? Should the #86 terminal be a ground? I believe it is opened. I saw a step by step method on here for checking the circuit. I did that and it brought me to where I am now, lost.
