Need to go back to basics. Check to make sure the connector at the pump is fully seated?
If OK there, need to check for voltage back at the pump?
If voltage, perhaps a bad new pump. If no voltage, have to trace back the circuit.
Let us know what you find when you do these tests.
Intermittent electrical problems are the worst to track down.
