What causes intermittent fuel supply failure in the Haval H6?
2 Answers
Haval H6 intermittent fuel supply failure may result from the following causes: 1. Hydraulic torque converter malfunction; 2. Automatic transmission failure; 3. Electronic control system issues. These problems require professional inspection and diagnosis at a repair shop to identify the exact cause before repairs can be made, as they cannot be resolved by vehicle owners themselves. Additional information: As an urban SUV, the Haval H6 offers excellent spatial performance. Beyond passenger space, it provides ample cargo capacity with 808L trunk volume, expandable to a maximum of 2010L when rear seats are folded forward.
My H6 also had this issue before. While driving, suddenly stepping on the gas pedal would have no response, and then it would work again after a while. This could be a minor or major problem. Later, I found out it was an issue with the fuel pump. After driving an old car for 70,000 to 80,000 kilometers, the fuel pump tends to fail to draw fuel properly, especially during highway driving. Another time, it was because the fuel injector was clogged with carbon deposits, causing poor fuel supply. Poor contact in the ignition coil can also cause this—check if the malfunction indicator light is flashing. The most troublesome issue is when the throttle pedal sensor fails, sending incorrect signals to the computer. This situation is quite dangerous, especially when overtaking and experiencing sudden power loss. I recommend not trying to fix it yourself; instead, take it to a professional mechanic to diagnose the trouble codes with a scanner, focusing on the fuel and electrical systems.
