Fuel pressure...don't crank it over and over. All you are doing is beating your starter.

With the car OFF put the gauge on..click the key a few time WITHOUT TRYING TO START. Note the pressure number....come back in 10 minutes...is the pressure the same.
I honestly doubt the battery cables are the issue here....afterall..you JUST changed the fuel pump.
And I did over exaggerate some things to push a point. If the fuel pump was the only thing recently replaced..it is the first place to start. As well..the pressure testing you are doing tells you nothing. I've recently replaced a pump or two for the same issues, there is a check valve inside and when they stick open..you have no fuel pressure to start the car.
