Fiat Cronos Fuel Pump Issue

It sounds like a fuel delivery issue, but several things could be at play. The symptoms you describe are consistent with a failing fuel pump. But rule out other potential causes first. Has the error code been checked and what does it say? A faulty fuel filter, a malfunctioning fuel pressure regulator, or even a bad sensor could mimic those symptoms. Before replacing the pump, inspect the wiring and connections to the fuel pump. A loose or corroded connector can interrupt the power supply and cause intermittent problems.

Thanks for the detailed answer. The error code indicates a problem within the fuel pump circuit, but I'm not sure how to inspect the wiring. Could you give me specific directions?

Given that the error code points to the fuel pump circuit, and you've experienced multiple symptoms, a defective fuel pump is highly probable. Considering the risk of misdiagnosis and potential damage to other components, I strongly suggest consulting a qualified technician. Trying to self-diagnose and fix the issue, without proper experience, might lead to additional expenses. They can perform a proper diagnosis, check the fuel pressure, inspect the wiring thoroughly, and confirm whether the fuel pump is indeed the culprit. If you are lucky it is just the cable or plug connection and the repair cost should be around 95€.

Thanks a lot. I understand and took it to a workshop. It was just a defective plug connection as you mentioned. Saved me a lot of money. I appreciate your time and expertise.
