Cold start seems oddly common with 9-5

Beginning to think cold start issues are the norm for a 9-5. Couple years ago I had cold start issues that seemed to be synonymous with the pump or check valve but it was occasional, not daily. Then is stopped for 6 months or so.
Then it became daily and in this scenario it was a coolant leak in #4 cylinder. New HG, zero issues for a year.
Then the pump went out and I replaced that 4 months ago. No issues period.
Now I have the cold start issues again almost daily and the only thing I can think of is the fuel check valve as the DIC, CPS, PLUGS, PUMP are brand new. As is nearly all electrical components with the engine (temp sensor, MAF, etc). The TB is cleaned yearly and is in good condition. Vacuum lines checked and are good.
Tried to prime it before starting but it's hard to tell if that helps (ie. it doesn't always).
