The following are the reasons why the Changan Star has no fuel and no spark: No fuel and no spark during startup: If there is no fuel injection or ignition during startup, then the crankshaft position sensor signal needs to be checked. For this model, the sensor is integrated inside the distributor. Check if there are any abnormalities in the sensor voltage signal or grounding, as the ECU will not control fuel injection and ignition if it does not receive the signal. Circuit issues: Focus on testing the three wires of the sensor. A common fault is the power wire having no electricity—check the fuse and wiring. You can directly supply power to the sensor; if the engine starts, it proves that the problem lies in the sensor circuit.

Should the 2021 Qashqai use 92 or 95 octane gasoline?

According to the Nissan Qashqai's vehicle manual, the Qashqai should use 92 octane gasoline. The difference between 92 and 95 octane gasoline: 92 octane gasoline contains 92% isooctane, while 95 octane gasoline contains 95% isooctane. This is the main difference between these two fuel grades. For gasoline, the higher the proportion of isooctane, the better the fuel's anti-knock performance. Different grades of gasoline should not be mixed: If a car's recommended fuel grade is 92 octane, occasionally using 95 octane fuel won't cause immediate problems, but prolonged mixing of fuel grades can damage the engine. When mixed fuels are used, the car may experience knocking during operation, which is more noticeable when the car is idling. Additionally, prolonged use of mixed fuels can lead to incomplete combustion, resulting in increased carbon deposits in the engine.
