What Causes the Fault Light to Illuminate on the Baojun 730?

[StJayla]

The engine fault light on the Baojun 730 may illuminate for several reasons. Generally, it can be due to an actual engine fault or a malfunction in the vehicle's onboard computer shortly after purchasing a new car. Additionally, the fault light may also turn on if the engine is not started. If you're concerned, you can visit a 4S shop to check whether there is a genuine fault. If there are no major issues, the fault light can be cleared using a diagnostic computer. The Baojun 730 may fail to start for the following reasons: 1. Battery depletion: The starter may initially turn but lack sufficient power, eventually making only a clicking sound without turning. Low temperatures in winter or leaving electrical devices on can prevent the vehicle from starting, especially after prolonged short-distance, low-speed driving in winter, causing the battery voltage to drop below the rated value and preventing normal operation. 2. Fuel flow obstruction: Avoid waiting until the fuel is nearly empty before refueling. No fuel pressure in the engine's fuel supply line often occurs on extremely cold mornings due to long-term fuel line contamination. In very low temperatures, water and debris can mix, blocking the fuel line and preventing the engine from starting. 3. Poor ignition system performance: In extremely cold weather, low intake temperatures can lead to poor fuel atomization in the cylinders. Combined with insufficient ignition energy, this can result in cylinder flooding—where excessive fuel accumulates in the cylinders, exceeding the ignition limit concentration and preventing the engine from starting.
