What are the reasons why the Haval H6 cannot start?
3 Answers
Haval H6 cannot start due to the following reasons: 1. The vehicle battery is low on power; 2. The fuel pump is damaged, preventing fuel from the fuel tank from being supplied for combustion; 3. The engine crankshaft position sensor or camshaft position sensor is damaged; 4. The engine lacks cylinder pressure. The Haval H6 is a compact SUV under Great Wall Motors, with body dimensions of 4615mm in length, 1860mm in width, and 1720mm in height, and a wheelbase of 2680mm. The Haval H6 is equipped with a 1.5T turbocharged engine and a 6-speed manual transmission, delivering a maximum power of 110 kW and a maximum torque of 210 Nm. It features a MacPherson independent front suspension and a double-wishbone independent rear suspension.
I often drive a Haval H6, and the most common reason for it not starting is a dead or aging battery, especially after a few years of use. The battery drains quickly when the weather gets cold. A stuck or faulty starter is also a big issue—if you only hear a clicking sound when trying to start the engine but it doesn't turn over, you should suspect the starter. Fuel pump problems can also prevent starting, whether it's an empty fuel tank or clogged injectors due to impurities, the engine simply won't ignite. Don’t overlook the anti-theft system either—dead key fob batteries or accidental system locks can cause issues. I’ve also experienced aging ignition coils or worn spark plugs leading to no spark. In short, first check if the dashboard lights come on, and try a simple jump-start. If there’s no response, check the fuses, wiring, or read the OBD error codes. Regular maintenance of the battery, fuel quality, and timely replacement of parts can prevent such troubles.
As a long-time owner of a Haval H6, I've noticed that frequent startup failures are often due to battery depletion, especially when headlights or air conditioning are left on after parking, causing the battery voltage to drop. A faulty starter is also a key issue; if there's no response during startup, it's likely the culprit. Fuel-related problems, such as an empty tank or clogged fuel lines, can prevent the engine from getting enough fuel to ignite. Additionally, issues with ignition system components, like faulty sensors or ECU errors, can interfere with startup. Key-related problems are not uncommon either, such as weak remote signals or anti-theft lockouts, which may require re-pairing. I recommend regularly testing battery health, ensuring sufficient fuel levels, and cleaning the fuel lines. Routine maintenance can help reduce unexpected breakdowns.
