Barchetta Engine Stalls After Fuel Filter Change

Hi, I have a 2001 Fiat Barchetta with a gasoline engine. The check engine light is on, and the engine stalls at idle. Plus, engine power seems reduced. I changed the fuel filter recently, and I suspect it might be related. Could this be a defective fuel pressure regulator?

I also own a Barchetta, though I'm unsure of the exact year. Your symptoms sound quite familiar. A faulty fuel pressure regulator can indeed cause those issues, especially after messing with the fuel system. Have you checked the fuel pump and pressure sensor? Any engine misfire codes?

Thanks for the reply! I haven't checked the fuel pump or pressure sensor yet. Where exactly is the fuel pressure regulator located on the fuel rail? Also, what kind of engine misfire codes should I be looking for?

Given the potential complications and your unfamiliarity with the fuel rail components, I would advise against attempting to diagnose the fuel pressure regulator yourself. It may be beneficial to seek a professional's opinion. A workshop should be able to confirm the defect.

Thanks for the advice. I took it to a workshop and they confirmed it was a defective fuel pressure regulator. Repair including parts and labor ended up costing 45€. Runs like new!
