What are the reasons why the Peugeot 408 won't start?

[McJohn]

Here are the reasons why the Peugeot 408 won't start: 1. No fuel: The fuel gauge shows below the red line, naturally making it impossible to start. 2. Dead battery: This could be due to prolonged headlight use without turning them off, resulting in a drained battery, or the battery's lifespan has expired. It is generally recommended to replace the battery every 2 years. 3. Incorrect gear position: For automatic transmission vehicles, the gear must be in P or N position when starting. If it's in R or D position, the car won't start. Some manual transmission vehicles also won't start if the clutch isn't depressed. 4. Fuel quality issues: Always refuel at reputable gas stations. When traveling, you can use a gauze wrap over the fuel nozzle to filter out impurities. 5. Excessive carbon buildup: Too much carbon deposit can also prevent the vehicle from starting.
