something simple you can try is switching out your battery with another and doing and entire day driving if your car fails to start with another battery or gives the same conditions of starting sometimes and not starting at other times then it could be a problem with your alternator probably some faulty wiring along the way or the alternator control unit is telling the alternator that the battery is fully charged when its not so it shuts off and doesn't charge the battery.

Your battery probably needs to be replaced. They normally last at least 3 years, and the better ones last up to around 7. They frequently die when the weather gets cold.

New battery needed.

ask somebody to help you and check the battery

After sitting around my car won't start. I had to jump start it to get it working, then I left it overnight without driving it. The next morning, I went for a long drive about 1hr30mins. I had to stop for petrol, so I did. The car started up straight away so I believe the altonator is working fine. It took 1hr30mins to get back home. Once I got home, I turned the car off and then I turned it back on within 10mins. Now the car won't turn back on. All I get is a single click sound and no crank.
