Replacing spark plug wires

Yeah thanks guys. I think the ticking might be a seal off one of the headers. Put new spark plug wires on tonight and coil. Fired right up. I went to replace the starter relay and now doesn't want to crank. Doesn't even try. I took a picture of it before I started and everything was put in right spots so I don't understand why it wouldn't fire. Or even sound like it's trying. Put the old relay back on still nothing. Could it be my ignition switch? Battery is good. Checking on it more after work tom but any ideas on this would be helpful.
