In the last week or so, it cranks for 2-3 seconds before starting whereas it used to start immediately. I installed a new starter 6 months ago as you all may recall. I also installed a K&N fuel filter 10 month ago. No issues until last week.

Research online and on FRRAX is pointing to a fuel pump or fuel pressure regulator. Or the battery. Or the spark plugs.

Car runs super fine once started and starts right up once it has been running. If it sits 6+ hours, it'll revert to needing extra time.

Suggestions?

If you turn the key on (but don't try to start it), do you hear the fuel pump prime for 2 seconds? If so, it's not a fuel pump relay. If not, it likely is a fuel pump relay. The oil pressure switch has an over ride that turns on the fuel pump when it "sees" oil pressure. It's a backup in case the relay goes bad.
