What should I do if the car battery is dead and the ignition cannot start?

1. There is residual power

If the car makes a clicking sound when turning on, but it does not ignite, it means the car still has residual power. At this time, remember not to force ignition several times, otherwise the remaining power will be quickly exhausted. When there is power available, you can push the car to start, but this is a last resort and cannot be used frequently as it will cause some damage to the engine and clutch. Automatic vehicles should especially avoid using this method to start.

2. There is no power

When the ignition cannot start, the most commonly used method is to use the battery wire to "match the light", which is the case. called borrowing a car to connect the wire. It's not easy to use it if there is no car nearby to borrow electricity.ctricity.

3. Find the reason

This situation is very easy to solve When the vehicle does not start for a long time, on the one hand, there are a large number of electronic problems. devices inside the vehicle that use a small amount of electricity. Although it is small, it can't bear to add a small amount. On the other hand, the battery structure also causes the car battery to self-discharge. When the vehicle temporarily fails to start, the vehicle will lose power.

The reasons why the car has power but cannot start are: it is in the wrong gear, the car is out of gas, The fuel pump is defective. , the starter is defective and the engine is defective. There are too many carbon deposits in the valve area.

1. Shifting into the wrong gear

Whene stopping the car and stopping the engine, the gear was not shifted to P, but directly to position P. In gear D. Shifting gear to D or R will not switch on the ignition.

2. The car is out of gas

In addition to the battery being dead and the ignition cannot be started, the ignition cannot be started when the car is out of gas of gasoline.

3. The fuel pump is faulty

If the starter can operate normally when the ignition is turned on, you need to check the fuel pipeline to see if this is the case, it is not not a problem with the fuel pump.

4. The starter is defective

If the starter is defective, this will also cause the light to fail.

5. There is too much carbon deposit in the throttle area

In this case, only by lightly pressing the accelerator can the fire be ignited. .
