What to Do When the FAW J6 Shows No Response Upon Turning the Key?
2 Answers
The solutions for a FAW J6 showing no response when turning the key are: 1. Check if the engine oil and coolant are sufficient, and consider replacing the oil suitable for the current temperature conditions; 2. Inspect the generator for any abnormalities and the working condition of the carbon brushes. If ineffective, it is recommended to clean the engine or calibrate the fuel pump; 3. For issues related to the electronic fuel injection engine, seek professional repair services. The FAW J6 truck is a commercial vehicle developed by FAW Jiefang Automotive Co., Ltd. of China. It is equipped with an electronically controlled engine, ECAS electronically controlled four-airbag air suspension, ABS, and ASR advanced braking technologies, making it suitable for long-distance highway transportation and special cargo transport.
The issue of no response when turning the key is frustratingly common in my repair experience. Here are the key points to check: First, inspect the battery—use a voltmeter to see if it's drained. If the voltage is below 9 volts, charge it immediately or replace it. Next, check the starter fuse in the fuse box; if it's blown, try replacing it with a new one. If these aren’t the problem, the starter motor or relay might be faulty. Listen carefully near the engine for a clicking sound when attempting to start—if it’s silent, the motor is likely the culprit. Additionally, some FAW J6 models have an anti-theft system that may lock up—don’t force the key, as this could damage more components. I recommend visiting a professional shop early for a diagnostic tool check to avoid bigger issues. Regular maintenance can save you from these headaches.
