Listen to Scott, that electric primer is misunderstood, not a pump, just a valve, nothing will happen with no fuel pressure (simply pump up the fuel bulb). These pumps are fairly robust, usually don’t break unless someone takes it apart an mis-assembles it. The only other thing that might ruin it is if somehow it gets stuck in the electric "on" position for a long period of time, but you say it "clicks" when wired directly, so this seems unlikely as well. Does it "click" when activated with the key switch?
One other area that is often overlooked while troubleshooting is the brass fitting on top of the carb. The typical diagnosis is pulling the hose and looking for fuel to squirt out of the hose. Keep in mind that the brass nipple can get plugged with crud causing the primer not to work as well. Put some WD40 in a syringe, then squirt it through the rubber hose while it is connected to the brass nipple to see if that is plugged up….
