Cold start is delayed, but starts - 2005 Nissan Quest

You have a faulty connection somewhere in your wiring. When engine is started, computer automatically places the engine into "cold start" mode. Don't be concerned about the whit smoke, that's just unburnt fuel when the mixture is enriched in cold start. After warm-up, cold start is shut down and all is normal. I said at first a possible wiring connection imbalance, not sure on this point, but the engine should do the cold start thing with the smoking and higher RPMs as soon s it fires up. I've no idea why the 10 second delay. Thing is, there's really nothing wrong, except for the delay after initial start-up.

If the climate control is on "auto" there is a delay before starting. For 15 minutes it is either freezing cold outside or needs repair. Depending where you live. Well anyway a way around the delay is to go to a manual setting and the system should start blowing right away.

Of course if it hasn't warmed up yet the air will be cold!!

Track the temperature gauge on the dash. As the temperature lift's off and approaches normal range heat should be coming from the vents,

New cars that are super efficient are very slow to heat up. The old gas gushers had plenty of heat to spare

So if you think it is cold where you live heck out the videos,
.
Cold start RAM 2500 at 35F 37C Fairbanks AK
Subaru Winter start up 44c

If the problem is only on cold start check cold start injector, it cuts out after the engine worms up .a faulty thermostat can delay worm up.

Just replaced fuel filter, all injectors, plugs and compute ?????? Why did you replace all these thing's ????? Did you have the computer programmed ?

Its a hot start issue.

Can be related to low fuel pressure or problem with crank sensor.

Also it can be weak battery or starter.

But possibilities are to be inspected to confirm what exactly it is.------

When the engine is cold cycle the ignition switch without starting the engine this is just to get the fuel pump going look at the injector and fuel line you may have a fuel leak that needs to be resolved

Depending on how Cold it is where you are, The cold will effect the Operation of the Tranny. I am pretty sure that your Tranny is Fine, Just Really Cold. Depending also on where you live, I use Valvoline Quick Change to service my Vehicles when I am on the Road. Have never had a Problem with them. On the Fluid, They make so many Different Kinds now adays that it is hard to Choose. Look in the Back of your Owners Manual and Use what is Suggested in there.
