Corolla automatically turns off after a few seconds of normal start-up, and then automatically turns off after a few seconds of start-up.

1, the simplest thing is to see if your corolla has been useless for a long time. If it doesn't work for a long time, just hit the car, step on the accelerator, and let the engine idle for 10 minutes or more before going on the road. As long as you keep the car running, you can properly change the intensity of stepping on the accelerator and run at high speed if possible.

If it is not the first case, look at the following situations. Generally, these situations need to go to a repair shop.

1, check the idle speed, and adjust it if it is too low.

2. Oil pressure, throttle, fuel injector (clean it, what is the atomization effect when injecting fuel), whether the spark plug is ineffective, and whether the ignition timing is normal.

If all the above are normal, go to the repair shop for inspection, or check it again in another repair shop. The estimated result is not very optimistic.

I hope it can be adopted.
