What are the reasons why the Besturn B70 won't start when hot?

The reasons why the Besturn B70 won't start when hot are: insufficient battery power, insufficient fuel, or faults in the starter and starter circuit. Appearance: The design of the new Besturn B70 2.0L fastback roof line is very eye-catching, while the double waistline design is faintly visible, creating a very stretched posture. The black exterior rearview mirror design, which is different from the body color, combined with the red calipers in the wheels, directly maximizes the sporty atmosphere. Power: The new Besturn B70 2.0L is equipped with a 2.0L turbocharged engine and a 6AT automatic manual transmission power combination, with a maximum power of 224 kW and a peak torque of 340 N·m, meeting the National VI emission standards. It not only provides strong power with a 0-100 km/h acceleration of 7.86 seconds, but also has an ultra-low NEDC fuel consumption of only 7L/100 km.
As a car enthusiast who frequently researches automotive issues, I believe that the difficulty in starting the FAW Bestune B70 after the engine has warmed up may be related to the fuel pump overheating. When the engine heats up, the internal components of the fuel pump expand, leading to insufficient fuel supply or unstable fuel pressure. The crankshaft position sensor is also prone to malfunctioning under high temperatures, sending incorrect signals to the ECU and causing ignition problems. Additionally, an aging battery or an overheated starter can contribute to the issue, as the battery's output capacity decreases when the engine is hot, resulting in weak starting performance. Prolonged driving with an inefficient cooling system can exacerbate these problems. I recommend first trying to wait a few minutes for the engine to cool down before attempting to start it. If the issue persists, promptly use an OBD scanner to check for fault codes or visit a repair shop for a comprehensive inspection. Safety should always come first to avoid affecting daily driving.
