What is the reason for the longer ignition time? What is the problem of the car not responding to ignition?

A car needs to be ignited and fueled to start normally. Generally, a car can be ignited quickly by twisting the ignition switch. However, as the car is used for a long time, it always feels that the ignition of the car is not as fast as before, and sometimes there is no response. So what are the reasons?

Why does the car ignition time take longer?

Fuel Injector

If the fuel injector in the combustion supply has poor atomization, it will lead to poor combustion. You can open the engine cover to find the engine and check the fuel injector and supply system.

spark plug

The spark plug in the ignition system has a high-voltage weak-fire phenomenon. If this problem can be eliminated, the problem of insufficient battery power can also be eliminated.

Engine starting system abnormal

There may be something wrong with the starter, which cannot drive the engine to normal speed. The starter needs to be maintained. If the starter makes unusual noises or is worn internally, it needs to be replaced.

What's the problem with the car not responding to ignition?

1. First, insert the vehicle key into the ignition ring and turn the key to the ignition position. For a one-button start vehicle, press the start button twice to see if the vehicle dashboard can light up and whether the vehicle can be powered on. Turn on the headlights and observe whether the headlights can light up. If they cannot light up, check whether the wire connectors are detached, loose, or poorly connected. Check whether the ignition component is faulty.

2. Make sure the vehicle is in P gear before ignition, and the manual transmission vehicle is in neutral. With the development of automobile safety, many models now cannot be ignited if the vehicle is not in P gear.

3. Start the vehicle and listen to the starting sound. If you can hear the "click-click" sound but the vehicle cannot start, it is very likely that the battery is low. You can start the vehicle by using a spare battery or a battery from another vehicle. Keep the vehicle in the starting state for a while to fully charge the battery. If the starter rotates normally, check the oil circuit, high-voltage circuit, fuse, spark plug, timing components, etc.

4. If there is no motor starting sound when starting the vehicle, check the starting harness, insurance, ignition switch, etc. Also check whether the battery is low.

What to do if the car ignition key cannot be turned

This is usually caused by locking the steering wheel.

You can first gently turn the steering wheel clockwise, and then turn the key with your hand. If it still doesn’t work, turn the steering wheel in the opposite direction and try turning the key again. If it still doesn’t work, the car’s lock cylinder may be broken. It is recommended to find a professional to repair it.

You should also pay attention to the maintenance of the car ignition lock cylinder on a daily basis. The normal operation is to stay in each gear for 1-2 seconds to give the CPU of the corresponding electrical appliance power to test time. If it is a keyless start, first press lightly to turn on the power, then press to do a self-check, and finally wait until the self-check is completed before pressing the third time to start the vehicle.
