Explorer Engine Stalling and Power Loss

My 2008 Ford Explorer (gasoline engine, 136,230 km) has a check engine light, frequent stalling at idle, and reduced power. Diagnostics suggest a fuel volume regulator issue. Could a faulty high-pressure fuel pump cause these symptoms?

I had a similar problem with my Explorer. Check engine light, rough idle, and less power sound familiar. Did you check the car sensors? Also, has your fuel efficiency dropped recently?

Yes, fuel efficiency has decreased. I haven't checked the sensors thoroughly. Which sensors are most relevant to these symptoms?

I'd check the oxygen and mass airflow sensors. DIY is possible, but a fuel regulator issue can be serious, so a mechanic might be best to avoid problems. A bad high-pressure fuel pump can cause chaos, so consider a workshop.

A mechanic confirmed a defective high-pressure fuel pump, requiring fuel volume regulator replacement. The repair cost 1510€. Thanks for the advice.
