Your right, now that I think about it. If the pump failed, vehicle could still be made to try to start. And the absence of hearing the pump run a few seconds when key was turned on, was an indication of pump related failure.
The idea and principle was still there though. Pump would run, build up some pressure, and then shut off. That way it wouldn't burn itself up, if someone left the key on, with engine not running.
It kind of idiot proofed things. The pump ran continuously once engine was running. There was a relief valve and return line. If engine was not running, the pump would stop. That way 100 percent of the fuel wasn't forced through the check valve return, making it much harder on the pump to continue to run.
