Under normal circumstances, when you open the key door before ignition, the gasoline pump will start working, because the gasoline pump is electric!
If there is really no oil and the gasoline pump cannot pump out oil, then it may not work if you add oil immediately because there is air in the oil pipe! If you add oil, open the key door, and then ignite after a few dozen seconds, it should be able to start!
Or step on the accelerator pedal multiple times to drain the oil. Bleed the air out of the oil pipe.
If it still doesn’t work, just use a 19mm fork to loosen the oil return screw, then pump the oil pump by hand until there are no bubbles in the oil, then tighten the oil return screw and try to ignite again. If it still doesn't work, go get it repaired.

Solutions when the car runs out of gas on the way:
1. Fill up the gas at the gas station
This requires going to the police station first. Proof, the proof mainly needs to include your name, ID number, purpose//unit name, and the company's official seal.
2. Call a tow truck
You can call a professional tow truck and tow it to a gas station. Or you can let a private car tow it, but traffic regulations and safety issues must be taken into consideration. When the engine is turned off, the brakes are not assisted.
3. Borrow oil
You can find a car and transfer oil from the car to your car. This method was used more often in the past, but now many cars have anti-theft oil designs, so you should take this into consideration when looking for a car to borrow oil. And pay attention to safety during operation and avoid open flames.
4. Roadside assistance
You can find a 4S store or roadside assistance company. Now some insurance companies and even credit card centers will provide this service. So you can directly contact these service numbers to get oil delivered to your car.
5. Add alcohol
All types of gasoline now contain alcohol, so as a last resort, alcohol can be added to replace gasoline. However, this method will cause damage to the vehicle, and the oil line must be cleaned afterwards. Unless life is at stake, this method is not recommended.
