The car doesn't starts

White smoke normally indicates steam, did the car overheat ????...if it overheated check hoses for leaks,,,, loss of water etc

get your battery checked

Have you checked the circuit between the key switch and the starter ?
There should be a starter relay and a neutral safety switch involved.

Could be a number of things but may want to begin by checking wiring to starter, battery, or even the ignition switch. These components may not turn your engine light on.

sounds like it having trouble starting. when was the last tune up ,and are there any codes on.

Take a test light to the small wire on the starter and have someone turn it to the start position. If the light lights up and the engine doesn't turn over, I would suspect the starter itself. If the test light doesn't light, try it in neutral and repeat test. If it still doesn't light up, it may be the PRNDL switch or the ignition switch itself.

loose or dirty battery connections ,starter solenoid faulty, low battery

It is very hard to help you when you give no details. But if it doesn't do anything when you try to start it you probably need to charge battery or get new one. If it is trying to start and doesn't sound weak then you need to have someone look at it. It doesn't sound like you would want to do anything yourself but if its not the battery, it doesn't sound good. Good luck

Hi
check the fuse box for fused fuse and replace them with the corresponding fuses.

Car doesn't turn over,but ignition turns on? Doesn't happen all the time,it just happens.. If I let it sit for a while it all of sudden turns over and starts. Happened twice this year..
