The most frquent problem that upsets car owners is a spark plug that cannot fire. Usually, the problem is caused by the lack of electricity in the car battery. If you cannot get your spark plug to fire, you can check your dashboard, which will help you to determine if it is caused by loss of electircity.
If your dashboard shows it is car battery problem, please keep the two things in mind: first, keep a cool mind and verify the problem; second, do not ignite your spark plug any more, otherwise, the car battery may use up all the electricity. To deal with the problem, of course, you can take your vehicle to the dealership or your mechanic, or use a Jump Star emrgency charger to provide power for your car. But there is a far more simpl way.
It would be the best if you have a spare battery. By connecting the spare battery to your car battery, and then your car battery will have enough power to ignite. If you do not have one, you can just borrow one. One thing you have to pay attention to when doing this is the positive poles of the two battries should be bonded together, while the negative poles bonded together. Do not ever mix them up.
However, if the promblem is not caused by low-power battery, and the car still cannot start after you provide it with extra power, you may need to use an OBD2 scanner to troubleshoot.
