Engine cut out, fuel pump not working

[aveo59]

I can hear the relay click
I checked for voltage at the pump today
Got 12v on two of the terminals and a about 5v on another
No noise. Or fuel coming from the pump
I have taken pump out and connected a 12v supply to it
It didn't work so I tapped it and it worked then stopped again
I put some lubricant in the inlet/outlets and it improved
I shall try it in car tomorrow
Can't get hold of a new pump yet.
Update
Put pump in, car started and died again.
Update.
Took pump out again,gave it a clean and put wynn's Dry Fuel in tank.
Done about 100 Miles so far
