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?

I installed a Racetronix 255LPH pump and hotwire kit back in 2010. I hope you don't need to contact them for support as they are not the friendliest folks for diagnosis. They'll just tell you to RTFM, including their installation docs and all the GM documentation on their website. Be careful putting the float arm back in if you're concerned about an accurate fuel level gauge. I've also intentionally chosen not to use the trap door because it's a street car.

Solely for resale purposes? Was it aesthetics? Water intrusion? Chassis rigidity?
