If you have a leaky backplate it will be easier for the impeller pull-in the easy-breezy air then try to suck up heavy liquid stuff. It would be like the opposite of priming the pump.

Sometimes, I have found you need to re-prime the pump given all the things you are reporting. Can you pour fluid into the pump inlet with a funnel???
