What to Do If Car Engine Doesn’t Start
If you turn the key in your car and nothing happens, it can be a very frustrating experience. There are a number of reasons why a car engine might not start, and troubleshooting the problem can be a challenge. However, by following these steps, you can increase your chances of getting your car started and back on the road.
1. Check the Battery
The battery is the most common reason why a car engine won’t start. A dead battery can be caused by a number of factors, including leaving the lights on, forgetting to turn off the radio, or a faulty alternator. To check the battery, use a voltmeter to measure the voltage across the terminals. A healthy battery should read around 12.6 volts. If the battery is dead, you can try to jump-start it using another car or a portable jump-starter.
2. Check the Starter
The starter is the component that cranks the engine over. If the starter is faulty, it will not be able to engage the flywheel and start the engine. To check the starter, listen for a clicking sound when you turn the key. If you hear a clicking sound, it means that the starter is getting power but is not engaging the flywheel. In this case, you may need to replace the starter.
3. Check the Fuel System
The fuel system provides the engine with the fuel it needs to run. If there is a problem with the fuel system, it can prevent the engine from starting. To check the fuel system, first check the fuel level in the tank. If the tank is empty, you will need to add fuel. Next, check the fuel lines for any leaks or blockages. Finally, check the fuel filter to see if it is clogged. If the fuel filter is clogged, you will need to replace it.
4. Check the Ignition System
The ignition system provides the spark that ignites the fuel in the engine. If there is a problem with the ignition system, it can prevent the engine from starting. To check the ignition system, first check the spark plugs. If the spark plugs are fouled or damaged, they will need to be replaced. Next, check the ignition coil. The ignition coil provides the spark plugs with the voltage they need to create a spark. If the ignition coil is faulty, it will need to be replaced.
5. Check the Timing Belt or Chain
The timing belt or chain synchronizes the movement of the crankshaft and the camshaft. If the timing belt or chain breaks, it can prevent the engine from starting. To check the timing belt or chain, you will need to remove the timing belt cover. If the timing belt or chain is broken, you will need to replace it.
6. Check the Engine Computer
The engine computer is the brain of the engine. It controls all of the engine’s functions, including the fuel injection, ignition, and emissions. If the engine computer is faulty, it can prevent the engine from starting. To check the engine computer, you will need to use a diagnostic scanner to read the trouble codes. If there are any trouble codes stored in the engine computer, you will need to repair the problem before the engine will start.
7. Call a Tow Truck
If you have tried all of the above steps and your car still won’t start, you may need to call a tow truck. A tow truck can take your car to a mechanic who can diagnose and repair the problem.
By following these steps, you can increase your chances of getting your car started and back on the road. However, if you are not comfortable working on cars, it is always best to call a mechanic for help.
