Versa 07 won't start when cold. No DTC Present

Hello there,
my wife versa take a long shot to start in the morning. It only happen with cold engine after sitting in the driveway for more than 10 hours. It take at least 20 seconds of cranking and idle poorly after that. This summer i've changed the fuel pressure regulator as per TSB NTB07-094c. Could it be failling again or maybe the pump? It look like the fuel pressure get long to build. No check engine light and no code stored in the ecm. Also, battery, spark plug and all maintenance stuff are good.

You might try turning the ignition on first, then the seat belt or wait 5 seconds before engaging the starter and this may let the fuel pump build up pressure to start easier.

A bad injector can cause the fuel system to not hold pressure too. Has the mpg declined or do you smell gas when the car is parked for the day?

New guy with a son with a Versa...........................can you listen carefully to hear the fuel pump when the key is turned on? Useful tool on Fords that can tell you much.

X2 to the leaky injector thing. I do not know on these but depending on how fuel pressure is controlled there can be other check valves in the system that could do some of the same effect. Often a check valve in the pump itself.

Can you mechanically check pressure on these or is it by software only? (no schrader valve)
