Reason 1 - Gasoline, like any other liquid, evaporates less when it is cold.You have seen this -- if you pour water onto a hot sidewalk it will evaporate a lot faster than it will from a cooler place like a shady sidewalk. When it gets really cold, gasoline evaporates slowly so it is harder to burn it (the gasoline must be vaporized to burn). Sometimes you will see people spray ether into their engines in cold weather to help them start -- ether evaporates better than gasoline in cold weather.

Reason 2 - Oil gets a lot thicker in cold weather. You probably know that cold pancake syrup or honey from the refrigator is a lot thicker than hot syrup or honey. Oil does the same thing. So when you try to start a cold engine, the engine has to push around the cold, gooey oil and that makes it harder for the engine to spin. In really cold places people must use synthetic motor oils because these oils stay liquid in cold temperatures.


Re ason 3 - Batteries have problems in cold weather, too. A battery is a can full of chemicals that produce electrons The chemical reactions inside of batteries take place more slowly when the battery is cold, so the battery produces fewer electrons. The starter motor therefore has less energy to work with when it tries to start the engine, and this causes the engine to crank slowly.

All three of these problems can make it impossible to start an engine in really cold weather. People either keep their cars in heated garages or use "block heaters" to get around these problems. A block heater is a little electric heater that you plug into the wall to keep the engine warm.
i hope it was convince answers

    probably its a dirty or bad injectors nozzles replacing them will save your fuel consumption and enhance cold starts and they will get worse after a while

My 2000 jimmy takes about 10 to 20 engine cranks in the morning when its cold out.when it starts its good the rest of the day. but its getting worse the amount of cranking the engine over in the morn

I'd use a fuel pressure gage, check fuel pressure, key on, engine off, first thing in the morning, 60--66 psi, spider fuel system. If you have the spider fuel stem, that system is noted for problems.
There is a service bulletin for cold start-up problems, caused by fuel poppet valves sticking. Once you get it started, it runs fine the rest of the day. The poppet cleaning procedure shows to be a shop procedure.

In the morning when 1st starting the car, the climate control does not work

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,

Where does a cold start sit on a chev spark 0.8 2008 and can that cause it not to start?

sounds like it needs a good tuneup, and maybe a battery! most cars start in about 5-10 seconds, even on a cold morning.if all is ok. good-day!

Starts but won t keep running

your first problem is that you are taking it to a mechanic with questionable qualifications
engines don't clear throats or have relays do it for them
the car has an onboard reporting system called an ECM and any mechanic who knows his trade would connect a scanner to the data plug and read the fault codes ( you can do that at autozone or like spares shops for free)
knowing the fault codes , the faulty sensors can then be fixed or replaced
from your description of the problem it appears to be a cold engine problem as you say runs well for the rest of the day
That indicates an ambient temp sensor, Baro sensor, MAP/VAF sensor and low fuel pressure from a faulty fuel pressure regulator sensor problem
find yourself an accredited service center that has experience on your make of vehicle and have it properly diagnosed

98 astro awd doesnt like to start in real cold weather (-18C) otherwise runs fine

I have a 98 and we just had a cold snap where it was super cold and I didn't start it for about a week. I had just got a new battery because mine tested out bad. Everything was good but now it doesn't want to get fuel. Cleaned all battery and relay connections and it's turning over great and fires with starting fluid but won't start. Guy at Napa said the fuel pump on these are known to not work well in the cold and suggested to warm the tank. I'm parked outside and can't move it to get it inside somewhere. Anyone know of good solution to this fuel pump not working in cold temps issue?

Starting Problem with cold outside

Check your starter relay on fender or firewall, they were known to take in moisture & obviously freeze up. Once it got warmer, thawed out & away you go.
