Ok 1 did you buy a brand new pump. 2 did it come with a replacement wiring harness. 3 if either 1 of those answers are no go buy a brand new pump with harness. If yes to both you got a bad pump.

sounds like fuel pump pressure. I had the same thing happen to me in a Lincoln mark VII and the electrical connection was shorting out in the fuel pump. I changed the fuel pump..Returned under warranty) put the new one on with filter and had no problem with it.

check your exhaust system and your muffler. a noisy fuel pump doesn't make sense, especially because a new one didn't change anything. if your muffler even has a tiny hole in it, it would make immense amounts of noise. the fastest way to check it (and you have to be very careful here) is to cover the exhaust pipe entirely with your hand RIGHT after starting the car (so it's still cold) if your hand is pushed off by a lot of force building up, then your exhaust is fine, if your hand can stay there with no resistance, and the noise gets louder, there is a leak in the exhaust system

the pump should stop when it builds up to the correct pressure. if it continues to pump and you smell fuel then you probably have a fuel leek. normally fuel consumption will increase with a leek, even slightly.

the fuel pump could actually be malfunctioning. and the reason that you are able to restart and drive again is because when you turn the key on it is allowing the fuel pump to pressureize your system. but while the fuel pump is continuasly running it is loosing the fuel pressure. this is common on the cheap fuel pumps. i am not sure about were you got the fuel pump from but in all of my experiances with this problem i find that the fuel pumps have been boughten at a napa store.
i hope this helps you out.
and you could attach a fuel pressure gauge on to the fuel rail and start the car and watch the pressure to see if it is droping.

the enginr oil pressure switch runs the fuel pump till the oil pressure is up to the normal operating range. When the pressure is up the relay kicks in and takes over the power to the pump. The oil pressure switch my be at fault if you can no hear the pump running when you turn the key on
