Renault Master Engine Stalling After Fuel Filter Change

Sounds like a classic case of a fuel pressure issue after a filter change. Could be a faulty fuel pressure regulator, especially if air got into the system. Does it struggle to start sometimes, or does it only happen when warm? A pressure drop could also point to a failing fuel pump, but let's start with the regulator. Did you make sure the new filter was properly seated?

Thanks for the quick reply! It only stalls when it's warm, and it starts okay most of the time, maybe a little hesitant sometimes. How can I check the fuel pressure regulator myself? Or is that something I should leave to a professional?

Given the warm-stall issue, the fuel pressure regulator is a prime suspect. Think of it like a tap that's sticking when it gets hot. While you could theoretically test it with a gauge, it's fiddly and requires some experience. Since it happened after the filter change and you're not super familiar with fuel systems, I'd suggest taking it to a workshop. They can properly diagnose it and replace the regulator if needed.

Thanks a lot for the advice! I took it to a local mechanic, and you were spot on. It was the fuel pressure regulator. Apparently, there was an error code logged after I changed the fuel filter. They replaced it for 45€, and the van is running perfectly again. Really appreciate the help!
