Croma fuel pump issues

I'm tearing my hair out here. I've got a 2009 Fiat Croma, gasoline engine, and she's decided to be a real pain. Basically, it won't start sometimes, or it'll start and then stall at idle. The check engine light is mocking me from the dash, and when it DOES run, it's rough and seems to be guzzling fuel. I hooked it up to a code reader, and it's throwing fuel pump errors. I've checked the fuses, which seem fine, but haven't had time to get deeper into testing the pump itself. Has anyone else had similar issues? Could it be something as simple as a dodgy connector?

A 2009 Fiat Croma with a gasoline engine is experiencing starting issues, stalling at idle, and rough running, accompanied by a check engine light and fuel pump error codes. The problem is suspected to be related to the fuel pump, with a potential cause being a corroded connector. A similar issue was resolved by cleaning and replacing the corroded connector, which successfully restored the vehicle's performance.

Sounds familiar! I had a similar headache with my Croma. Exact same symptoms, engine light and all. Did you check the cable and plug connections for the fuel pump? Is the connector perhaps corroded? That was the culprit in my case.

Interesting! I haven't had a chance to dig in properly yet, but I was hoping it might be something relatively simple. Where exactly was the corrosion on yours? Was it obvious, or did you need to get the multimeter out to properly diagnose it?

Yeah, in my case, it was pretty obvious once I actually located the connector – tucked away nicely near the fuel tank. A bit of green crud had formed on the terminals. I cleaned it up with some contact cleaner, but honestly, it was a temporary fix. It came back a few weeks later, and I ended up taking it to a workshop, they changed the corroded connector and also cleaned the contacts. So, if you find corrosion, clean it up and replace the connector.

Thanks a bunch for the advice! Turns out it was exactly as you suspected – corroded connector on the fuel pump wiring. I ended up replacing the connector and giving everything a good clean, and she's running like a champ again. The whole repair cost me 95€ which is a lot better than a new fuel pump!
