Edge Diesel Engine Stalling Rough Running

Sounds familiar! I had a similar issue with my Edge – though I have the petrol engine. Stalling, rough running... the whole nine yards. It could be the fuel pump going bad, but before you go ripping things apart, have you checked the wiring and connections to the fuel pump itself? Especially the plug connector. Sometimes a loose or corroded connection can cause all sorts of weirdness. Fuel pumps deliver fuel from the fuel tank to the engine's fuel injection system. A bad electrical connection will cause the pump to not get enough electricity or the signal that it should get electricity. That can easily cause the symptoms you describe.

Interesting. So, when you say 'wiring and connections', are we talking about tracing the whole fuel system, including all the fuel injectors, or just focusing on the fuel pump itself and its immediate wiring? What exactly did you look for when you had the similar issue?

Nah, I wouldn't go digging into the whole fuel system just yet. I'd focus on the fuel pump first. Check the connector that plugs directly into the fuel pump. See if it's loose, corroded, or if any of the wires are damaged. Honestly, I'd recommend getting it checked out by a workshop. These modern cars are so complicated, and messing with the fuel system can be risky. It's probably just the fuel pump as said, but they will check the cables and all connections before replacing it anyway.

Thanks, that's really helpful. I appreciate the insight. I will check the connections, but it's probably beyond my capabilities. I've already made an appointment to get it checked at the shop; they said it'll be about 95€. Hopefully, it's just a loose wire like you suggested. I will post what the shop finds in case anyone else runs into this problem. The issue was as suggested a cable or plug connection!
