Anyone know what this is?
A noisy pump. Most aftermarket pumps are noisy. As long as its a steady sound what are you worried about? Is this a Cadillac?

I think you have a problem. The pump could be miswired or the relay could have fused contacts. Normally, if you turn the ignition switch to “on”, without starting the engine, the PCM will run the pump for about three seconds and then turn it off.
