The Flow Max RV Fresh Water Pump - 12 Volt - 3.3 Gallons Per Minute - 45 PSI # LC689052 sounds like it doesn't have a proper priming which it is designed to automatically do. There are some things to check in the owners manual that I've made a copy of to assist. Check each one of these suggestions one at a time to narrow down the possible causes.

I'd also turn off the bypass to your hot water heater as that fitting may be the issue, so check it both ways.
