If your car doesn’t start, but all lights can be frustrating and worrying. It is a situation in which you can be confused and cannot be sure what you should do next. But they are not afraid, since there are several potential reasons for this problem that range from minor electrical problems to serious mechanical problems. In this comprehensive guide, we will examine the possible causes and provide you with practical solutions to bring your car back onto the street.

If your car doesn’t start, but all lights arrive: electrical system
Before you immerse yourself in the possible causes, it is important to understand how the electrical system works in your car. The electrical system consists of battery, starter, alternator, fuses and cabling. If you turn the key around in the ignition, the battery sends the starter electricity, which includes the engine and lets it start. The alternator then takes over the electrical components while the battery is charged. So if your car does not start but all lights occur, this can be for the following reasons.
Check the battery
Check one of the first things when your car doesn’t start, but all lights are the battery. Although the lights and the radio may still work with a small load, the battery may not have enough electricity to hire the starter. Start with the visual check of the battery on signs of corrosion or damage. If everything looks okay, check a multimeter to check the battery voltage. Ideally, the voltage should be around 12.6 volts. Everything below 12 volts shows a weak or unloaded battery.
If the battery voltage is low, you can try to start the car with sweaters and another vehicle with a healthy battery. Let the two batteries connect for a few minutes and then try to start your car. When it begins, this means that your battery must be loaded or replaced. However, if the battery does not hold a load or start, it does not work for a new battery.

Examination of the fuses and relays
If the battery is in good condition, the next step is to check the fuses and relays. A blown fuse or incorrect relay can disturb the current flow to the starter and prevent the engine from starting. Start with finding the safety box, which is usually under the dashboard or in the engine compartment. Contact your car’s car trade to determine the specific location of the securing in connection with the starter or ignition system.
Carefully remove the suspect and examine it for signs of damage or a broken filament. When the fuse appears intact, check a multimeter to maintain continuity. If the multimeter does not show continuity, this means that the backup is blown and must be replaced. In a similar way, check the relays in connection with the starter and ignition system for signs of damage or malfunctions. If relays are incorrect, they should be replaced to restore the correct functionality.
Evaluation of the ignition system
If the battery and the fuses are in operation, the problem can be within the ignition system. The ignition switch, the ignition coil and the starter magnet are critical components of the ignition system. A faulty ignition switch can disturb the current flow to the starter and prevent the engine from starting. In addition, a worn ignition coil may not offer enough tension to ignite the fuel-air mixture in the engine.
To check the ignition switch, turn the button into the “A” position and watch the dashboard lights. If the lights do not illuminate or flicker, this shows a problem with the ignition switch. In such cases, the ignition switch may have to be replaced by a qualified mechanic. Similarly, a faulty ignition coil can cause start problems. If you suspect a faulty ignition coil, please contact a specialist to receive proper diagnosis and a proper exchange.
Investigation of the starter engine
The starter engine is responsible for turning the engine over and starting it. If the starter motor fails or malfunctions, your car does not begin, even if all lights arrive. A click of a faulty starter engine is a click sound when you turn the button in the ignition. However, remember that some starters can fail tacitly without noticeable noise.
To diagnose a faulty starter engine, you can try to tap it easily with a hammer while someone else turns the key in the ignition. When the car begins, this indicates that the starter engine has a dead point and has to be replaced. However, if typing on the starter does not work, it is best to consult a specialist for a thorough inspection and a potential exchange.
Additional tips for troubleshooting
If you have checked the battery, the fuses, the ignition system and the starter engine and still cannot determine the underlying problem, you will find some additional error lout tips here:
Fuel system
Make sure your car has enough fuel. If the fuel display is incorrect, it can indicate inaccurate reading. Try adding a small amount of fuel or a fuel additive to clean the fuel system.
Security system
Some cars have an immovable system that can prevent the engine from starting when it recognizes unauthorized access. Check whether the safety light flashes in the dashboard or contact the manual of your car to get instructions for resetting the immobile system.
transmission
If you have a manual transmission, make sure that the coupling pedal is completely integrated when the car starts. A faulty clutch position sensor can prevent the engine from turning over while the electronics work.
Wiring and connections
Check the wiring and connections related to the starter, the ignition system and the battery. Loose or corroded compounds can interfere with the current flow and prevent the engine from starting.

If your car doesn’t start, but all lights come up: conclusion
If your car does not start but all lights appear, it is important to stay calm and systematically remedy the potential causes. First check the battery, fuse and relay to ensure that you are in good condition. Rate the ignition system, including the ignition switch, the ignition coil and the starter magnet. Finally, examine the starter engine for signs of a malfunction. If you cannot identify the problem, it is best to consult a professional mechanic for a thorough diagnosis and repair.
