Slow Turnover after new fuel pump install

[IIv SHaDoW vII]

I replaced the fuel pump because the old one was going out. I noticed that the car now takes longer to turnover. Could the fuel pump be bad, or weaker than the old one? There are no leaks from the lines on top of the tank. I made sure to check them before reassembling everything. I also checked under the rear of the car for signs of leaking to make sure I didn't kink and break the hard line. The car starts every time I attempt to, but it just takes longer to start than it did when my old pump was on there. Once started, the car runs fine with a steady idle. The new pump also seems to be pressurizing the system because I can hear it before trying to start the car. Also, today I primed it 3 times before attempting to start and it still took longer than expected to start. The gas cap is screwed on tight. Any ideas?

Maybe the fuel pump is electrically bad. If it's drawing too much current, the starter will experience a voltage drop and spin slower. Where did you get it from? Can you return it? What kind of fuel pump is it?

Is it cranking over slow or cranking over at the same speed but talking longer to start?

Cranking over slow means your battery might just be low.
Taking longer to start may be a sign of something wrong with the install.

It is cranking the same but taking longer to start.

Did you replace the big cap seal on the sending unit when you reinstalled it? That seal could be leaking vacuum pressure out the top of your tank. Resulting in the same problem as if your gas cap was loose. I noticed when I took my fuel pump out and just put it back in it took longer for it to start for about the next day or so. Takes time to purge all the air from your fuel lines again maybe?
