Modus Stalling Rough Idle

That sounds eerily familiar! I had almost the exact same symptoms with my old Opel Astra a few years back. Engine wouldn't start half the time, stalling, rough running... Nightmare. Did you also happen to notice any weird noises coming from the fuel tank area before all this started? I didn't connect it at the time, but looking back, there was definitely a faint whining sound.

Interesting. I haven't specifically noticed any unusual noises from the fuel tank area, but I'll definitely pay closer attention now. When you had these symptoms with your Astra, did the error codes also point towards the fuel pump? And what ultimately ended up being the problem? Trying to get an idea if I'm on the right track before I start tearing everything apart.

Yep, the codes all screamed fuel pump failure on my Astra too. I messed around checking fuses and relays like you, but in the end, I just took it to my local workshop. They confirmed the pump was kaput. Honestly, unless you're really confident with car electrics, I would recommend getting it checked out professionally. Could save you a lot of time and frustration.

Thanks for sharing your experience! I appreciate the advice. I took your suggestion and brought it to the workshop. Turns out, as suspected, a defective connector was the culprit. New connector fitted, total cost 95€. Runs like new again!
