Actually I have the opposite view. On mine I can hold the prime switch WITHOUT CRANKING the engine I can hear the pump running and slow down when the carb is full. It is a very slow click when it is full. The one time I never heard it slow down was because of a stuck open float / needle and seat. I found out about it with ever trying to start the engine.
My airplane uses the same Bendix pump. The pre-start checklist from Grumman says to start the electric pump. Listen for it an read the fuel pressure gauge for 4-6 PSI. Then use the injection system to squirt fuel direct into the cylinders and start the engine.
