Well when you put in the new pump did you replace the screen on the end?

Did you replace the fuel filter?

If say the pump is trying to pump and say the filter is stopted up the pump turns on, feels a lot of resistance and then shuts down.

Sorry to say looks like you need to pull the pump out again.
