The 4y engine automatically shuts down after half an hour. If you start it again, it won't start. What happened?

Hello, the engine is old and there are many related problems.

: (1) Check whether the battery is charged (honking the horn to see that the noise is louder than usual "No sound means there is no electricity or insufficient electricity; You can turn on the headlights at night to see if the lights are brighter than usual, not bright enough, and the battery is dead. Another is that the instrument is flashing when it is started, which is also the lack of battery power. At this time, call someone to come and get the electricity to start. (2) If it is confirmed that the battery is charged and still cannot be started, and the engine can't hear any sound when the ignition is started, you need to check whether the starter fuse is blown and whether the relay works normally (if the relay can't, you can only find a repair shop). (3) If everything is normal after the above two steps, the ignition engine can hear strong starting sound, or the car can't start, it is necessary to check whether the spark plug trips, whether the high-voltage line works abnormally, whether it is hot or cracked, whether the fuel pressure is normal, whether the throttle signal is normal, whether the carbon canister solenoid valve works normally, and whether the EGR valve works normally. I can't do the third step myself, so it's better to call the repair shop. I hope I can help you.
