If you jump power to the pump, AND THE PUMP HAS GROUND, but it doesn't run...it's defective.
Do you know that the ground side is good?

It could be. That's not unheard of. I'd clean all my connections including grounds there around the sending unit before spending more money on another pump.I’m guessing this pump, despite have less than 30 minutes of runtime is faulty. I’m thinking I’ll try to hunt up a Delco pump if I can find one.
HOW are you "checking" the grounds? I would be testing for voltage on the pump ground wire, as close to the pump as practical. One volt is about typical, but less is better.It ran for two minutes.
Then it quit.
same issue. Started right up with carb cleaner but the pump isn’t pumping. Ran a line direct from a hot 12 volt source to the pump and nothing. And of course checked all my grounds all that, again...all is normal..
