Have to crank a long time for engine to start when cold.

I recently brought my 86 back to life. It is a 16v with USDM harness.
I just swapped the fuel pump out with a delphi unit from Autozone, becasue my old pump had died.
It ran fine for a short while, but then all of a sudden, I am running to an issue where I would have to crank for a good 10-15 seconds and the motor slowly cranks to life. Once it is warm, it will crank up just fine.
I have scoured this forum as well as other outlets and am guessing it could be a few possible issues, but I figured I should diagnose the issue before I start replacing random stuff on my car.
- I read somewhere that the fuel damper can make a significant difference in this.
- Could be the fuel filter
- Maybe the cold start? but then I havent heard anyone speak specifically about my issue.
Another maybe important detail is that the car had been sitting for about 3 years. and the gas in there was very old. I did refill it once I got it running again, but this was the reason why I thought maybe it could be my fuel filter.
Can anyone tell me what I should look into or any tests I should perform to get this worked out.
Thanks
