If the car starts right away, your problem is most likely a dead battery. Charge the battery and clean the terminals and cable connectors to ensure good contact. If your car does not start by jump-starting, you may have a problem with your starter, alternator or another component of the electrical system.
Can a car battery be so dead it won’t take a jump?
No, a car battery is never “too dead” to jump-start. If the jump-start doesn’t work, you may have a faulty alternator or a dead battery that necessitates a replacement.
If jump starting gets your engine started and running, but the car will not start again once you turn it off, the battery is probably the problem. In this case, the alternator is doing its job of keeping the battery going once it has been jumped, but the battery can’t hold a charge when the alternator is shut off.
How do you tell if it’s my battery or alternator?
Jumpstart your car. If you can turn the engine on, but it dies shortly thereafter, your car alternator likely isn’t able to charge the battery. On the other hand, if you jumpstart the car and later on it fails to start on its own, it’s likely a dead battery.

Why won’t my car start but battery is good?
If you have a good battery, enough fuel, and everything else looks fine, and your car won’t start, you could have a faulty spark plug. Your car requires the correct air-to-fuel ratio and spark to start the combustion system. If broken, the spark plug may prevent fuel ignition, and the vehicle may not move.
Why won’t my car start but the battery is fine?
Bad Starter
If the battery seems fine, the problem may be in your starter. A starter is a small motor that draws electrical current from the battery to start the engine. When a starter fails or malfunctions, you may hear a clicking noise when turning they key in the ignition.
If the engine starts but dies immediately, your alternator probably isn’t keeping your battery charged. If a jump starts and keeps your car running, but the car can’t start again off of its own power, a dead battery is probably your answer.
When your car won’t start but all the lights come on?
If your headlights can turn on, but your car won’t crank, that means that your battery is charged, but either the starter or ignition is the problem. If the starter or ignition is the problem, a starter engine can be jumped by using a charged battery.

Why won’t my car start but the radio and lights work?
If your car’s lights and radio are functioning, there’s at least some power coming from the battery. It takes much less energy to work the headlights than the starter motor. If it’s not the battery and the engine won’t crank, the fault is likely in either the starter solenoid, starter motor, or ignition switch.
How do I know if my starter is good?
Connect the remote starter switch to the battery positive and the solenoid (smaller wire) terminal on the starter and click the switch. If nothing happens, you’ve got a bad starter. If the starter turns, the problem is in the electrical system.
How long does it take a car battery to recharge itself?
Generally, if you can keep your engine RPM up, your alternator will charge your battery at a faster rate. If you are driving on a motorway, you should be able to charge your car battery in 30 minutes. If you are driving in the city, it may take an hour or more.
When I turn the key nothing happens no click?

How do you diagnose a no start problem?
Ignition timing on a no-start can be confusing, but it can still be tested by connecting a timing light, then watching the timing marks while an assistant cranks the engine. While this may or may not be base timing as specified by the manufacturer, it does let you know where the spark is occurring.
Is it my battery or starter?
When you attempt to start the vehicle, is there a clicking sound, but it won’t turn over? That may be a good sign. If a jump gets the car running, but won’t turn over again once it’s shut off, a dead battery is likely the cause.
