Extended Turnover

2017 Honda Civic LX

In the morning, when I go out to start the car, the turnover is extended a few seconds longer than normal. Only does it once a day (in the morning). The battery was recently replaced (tests normal). Alternator and starter test normal too. Started a few weeks ago. No lights on the dashboard. The car drives smoothly otherwise. Any advice? Could temperature changes be causing this?

Thanks

Miles on vehicle and temps might help. Also, is it pushbutton start or have a key?

If key- it could be a fuel issue -- try clicking to "On" position and let the fuel pump run a second or two.

Report back and let us know....

The car has 65k miles and it has key-start. Followed what you recommended; revved normal. No lights has turned on either. Temperatures have been constant but the issue is still going on. Could it be carbon build-up?

Also, allowed it to pump for a second but it still does it. Still only one time a day (in the morning)

:dunno:

If that is the only issue...and the vehicle is good to go....I'd just drive it. Probably something in the fuel system is draining overnight.
