Twingo Diesel Starting Issues

Hi, I've got a 2014 Renault Twingo diesel with 70621 km on the clock. Recently, it's been a nightmare to start, sometimes stalling at idle. The check engine light is on, and the engine runs rough. Fuel consumption seems higher too. I pulled the error codes, and it points to a fuel pump issue. I've checked the pump itself and it seems fine, so I'm thinking it might be a faulty cable or plug connection. Any ideas?

Hey! Fuel pump issues are tricky. Does the engine always stall at idle, or just sometimes? Also, have you checked the fuel filter? A clogged filter can sometimes mimic fuel pump problems. It's a cheaper fix, so might be worth a look before diving deeper.

Thanks for the reply! It doesn't stall every time, but frequently enough to be a pain. I haven't checked the fuel filter yet, but I will do that tomorrow. But if the fuel filter is the issue, why would the error codes point to the fuel pump?

Error codes aren't always spot-on. A clogged filter restricts fuel flow, which could cause the pump to work harder and trigger a fuel pump-related code. But given all the symptoms and the error code, there's a strong chance you're right about the pump or its connection. It might be worth getting it properly diagnosed at a workshop, especially with the intermittent stalling.

Okay, thanks for confirming my suspicion. I checked all the connections, cleaned everything up, and it seems to have solved the problem. I also replaced the fuel filter while I was at it. The car runs perfectly now. Eventually the repair cost me 95€
