I assume you mean that it turns over a few more times before it catches. There are a lot of things that affect this - battery voltage (starter speed), fuel pressure, compression, ignition timing.
There is a valve that keeps the fuel pressure up for a while after you shut the car off, so it'll restart a little faster. It might be leaking down a hair faster. The new pump may be pressurizing the system just a little slower than the old one. No big deal. It's obviously providing sufficient pressure and flow - the pressure and flow required to start is much, much lower than under full acceleration. So if the car is driving OK, you've got plenty of pressure and flow.
Yes, it may be different, but it probably isn't a problem. It's nice when your engine catches the instant you turn the key, but a few cranks before it catches is not the end of the world. You could spend a lot of time and effort figuring out why, but it's not really a problem. If you start seeing longer and longer times, that would be an indication something is going south. I'd start with ignition - make sure they're the right plugs, gapped properly. But taking a couple/three seconds to catch isn't too bad. Especially when you're talking about a 19 year old car. Yes, we may have had no problem getting up to pressure instantly when we were 19 years old, but cars are different. This is the equivalent of asking a 65 year old to perform as well as the young stud.
