Extended cranking before starting

No fault codes would suggest that either the starter is not cranking the engine fast enough. Since you have fitted a new battery, check all the battery connections, particularly the earth to the engine and body. If the engine must crank fast enough for the crankshaft position sensor to send a signal to the ECU to switch on the fuel pump. A faulty starter motor could also cause this, as could a faulty fuel pump relay. These items need testing.

Sounds like the fuel system is losing pressure when the car is off (fuel draining out of the lines).

If so, it is either an external fuel leak (gas on the ground) or an internal fuel leak (gas leaking past an injector into the motor or at the fuel pump's pressure regulator...gas draining back into the tank).

If it runs fine when running, my guess is that it is a small leak at the pressure regulator (small debris on check ball seat).

As long as it is not leaking gas on the ground, I would drive it as is. The OEM pump is probably better than the replacement part that they would use.
