Of course not. You proved that the starter relay works, and that its coil- is already grounded. The key in "crank" applies +12 V to the yellow wire (rel. to BATT-). Measure that is happening. I doubt it since when you apply +12 V w/ a jumper the relay engages. If the yellow wire stays dead, start tracing it from the key thru the firewall to the starter relay to see where you don't get +12 V in "crank".

BTW, while in there, a simple and fairly effective anti-theft is to install a push-button switch, in series w/ the yellow wire, in a secret location. Some people re-purpose an existing switch. For "valet bypass", wire a toggle switch in parallel, if you will allow valets to drive your classic ("I didn't scratch it"). A thief could still hot-wire the car under the hood, but most prison teaching is the movie method of yanking and twisting the wire at the key switch.
