C70 fuel pump connector issue
Summary of the thread
The 2000 Volvo C70 was experiencing starting issues, stalling at idle, rough running, and increased fuel consumption, with a check engine light indicating a fuel pump problem. The likely cause was identified as a faulty fuel pump connector, which can become corroded or loose over time. After confirming the issue, the garage repaired the damaged connector and cable, resolving the problem and restoring the car's performance.

Misfiring is possible, hard to tell with all the other symptoms. You mentioned a dodgy connection – was that the fuel pump connector itself? Where should I be looking for this issue? Anything else to consider before I drop the tank?

Yeah, I'm not super mechanically inclined, but from what I remember, the mechanic said it was a known issue with the connector to the fuel pump. Like, it gets corroded or loose over time. Honestly, I'd just take it to a good workshop, even if it's just for them to check the fuel pump connector, as I did. They'll know exactly what to look for. It may be just a connection problem, or something more serious. No need to replace the fuel pump yourself for nothing!

Thanks for the insight! Sounds like the connector is the most probable cause. The garage confirmed that the connector and the corresponding cable were indeed damaged. They repaired it for a reasonable 95€, and now everything runs smoothly again! I really appreciate the help!

Dude, I had almost the exact same thing happen with my C70! Seriously annoying. Stalling, rough running, the works. I bet you anything it IS the fuel pump. The mechanic mentioned something about a dodgy connection being a common culprit. Is your carby misfiring?
