My car is Chevrolet's new Sail EMT car, so I can't light the exhaust pipe with full fuel.

You should be talking about the engine fault light, right? There is no fault light in the manual transmission. Suggest following my steps: 1. Go to the 4s shop and do a fuel pressure test. If the oil pressure is high, check whether the oil pressure regulator is damaged. I don't think there is something wrong with your fuel injector, but the high oil pressure leads to the excessive fuel injection and the strong oil-gas mixture of the engine, which leads to the inability to refuel or shoot after refueling. 2. If there is no problem with the oil pressure, the regulator should not be damaged. Further check the vacuum tube of the regulator for leakage. If there is a leak, your idle speed must be around 1500. 3. As for the electronic throttle, if the above two are all right, it is recommended to try the air flowmeter first. If it can't be solved, then use the decoder to match the throttle. 4. If the problem cannot be solved, it is suggested to try to replace the throttle body ... I think it is dead ... Hehe. Because I repair Volvo, I don't know much about Chevrolet. I'm just suggesting ... try.
