Veracruz Engine Stalling

My 2008 Hyundai Veracruz, gasoline engine, with only 29471 km, has a problem. The check engine light is on, the engine stalls at idle, and the power feels diminished. I suspect a defective fuel volume regulator. Could a faulty high-pressure pump be the cause?

Summary of the thread

A 2008 Hyundai Veracruz is experiencing engine stalling at idle, an illuminated check engine light, and reduced power. The suspected cause is a defective fuel volume regulator, potentially due to a faulty high-pressure fuel pump. Similar symptoms in another Veracruz were resolved by addressing these components. A professional diagnosis at a workshop is recommended to confirm and fix the issue.

I had similar issues with my Veracruz. The illuminated check engine light, stalling at idle, and reduced engine power match my experience. For me, it was a failing fuel volume regulator caused by a defective high-pressure fuel pump. Think of it like a heart struggling to pump blood; the fuel volume regulator is the valve, and if the pump is weak, the valve can't do its job properly. Have you checked the car sensors and fuel injection?

Did your Veracruz show any other unusual behavior before the fuel volume regulator failed completely? Were there any subtle hints I might have missed?

Before it failed, my Veracruz had intermittent rough idling, almost like a slight tremor. There were also occasional engine misfires, especially during cold starts. It was as if the engine was clearing its throat. Given your symptoms, I suspect a defective high-pressure pump is causing the fuel volume regulator issue. I'd recommend a trusted workshop for a diagnosis. I had to spend 1510€ to fix that.

Your explanations have given me the clarity to proceed with repairs. A trip to the workshop is in order. I'll report back with the final diagnosis.
