Peugeot 807 Fuel Pump Cable Issue

Hi, I've got a 2007 Peugeot 807 diesel. Recently, it's been a nightmare. Engine won't start sometimes, stalls at idle, and the check engine light is on. It's running rough, fuel consumption seems higher, and there's an error stored. Mileage is at 204981 km. Could a defective fuel pump cable cause all this?

A 2007 Peugeot 807 diesel was experiencing starting issues, stalling, rough running, increased fuel consumption, and a check engine light. The problem was suspected to be related to a defective fuel pump cable. After checking the error code and consulting with a mechanic, it was confirmed that the issue was indeed a faulty fuel pump connection. Replacing the cable and plug resolved the issues, restoring the vehicle's performance.

Sounds familiar. I also drive an 807 diesel. Had similar issues. Have you checked the error code? Could be the fuel pump relay or even just a dodgy connection. High fuel consumption definitely points to fuel delivery problems.

The error code points to the fuel pump itself. You mentioned a dodgy connection. Where exactly should I be looking for this dodgy connection? Is there a common spot where the cable might be damaged or corroded?

For me it was indeed the fuel pump connection - at the pump itself. Visual check is difficult. I would suggest going to a workshop, it is most likely something they can sort out quickly. Good luck!

Thanks for the insight. Took it to a mechanic, and you were spot on. It was a defective fuel pump cable. New cable and plug, cost me 95€. Runs like new!
