Yes if ur car has many or some sort of engine problems
Need more information like year, make, model and engine of car.
warm start is when your car has already been started an is hot, a cold start is wheen you have just started the car for the first time of the day, or month....
The most common reason for a car not starting, on a cold day, is the battery needs to be charged. Make sure the battery has a full charge.
It is not so much hard for a car to start when the engine is cold as it is easier for a car to start when the engine is warm.Cars that are hard to start in the cold are usually not new cars any more and because of wear and tear there is more likely to be something that doesnt work as well. when fuel is warm it ignites more easily.
one reason is that your batterie is deader than a door nail. or you cable connections are loose. if your batterie is dead. something on the car is staying on while the key is on the off position. or if you live in cold weather and the wind is blowing, facing the front of the car twoards the wind can make the temperature outside the car drop and cold, cold weather can drian a batterie.
around 30 or 40
too cold!
If a car won't start in cold weather it is possible that the valve guides have been worn. This often happens in cars that have been using ethanol as a primary fuel.
the temp sensor opperates the choke flap , and if the sensor is faulty the choke will stay open and make it difficult to start, and on cold mornings some times make it impossible to start
A cold wind should have no effect on the car engine.
The car shakes because your engin has been cold and you sudenly start the car it will shake
try checking your battery usually it is the lack of cold cranking amps
