Crown hybrid fuel issue

My 2021 Toyota Crown hybrid is giving me fits. It's got just over 25,000 km on it. Lately, it's been struggling to start, sometimes stalls out at idle, and the check engine light is mocking me constantly. When it does run, it's rough, and my fuel consumption has definitely gone up. I scanned it, and there's an error code related to the fuel system. I've checked the obvious stuff – fuses look good, but I'm suspecting something with the gasoline delivery. Could it be a defective fuel pump? I read that a loose cable or plug connection can also cause this. Anyone else experienced this?

Sounds awfully familiar. I had similar symptoms on my Crown – though I can't recall the exact error code. Stalling, rough running, the whole shebang. Have you tried checking the fuel pump relay and its wiring? That was one of the first things I looked at before tearing into the fuel pump itself.

Thanks for the tip! The fuel pump relay seems fine, I checked with a multimeter. I am now leaning towards a defective fuel pump. Is your Crown also a hybrid? How did you solve this?

Yep, mine's a hybrid too. After chasing my tail for a while, I ended up taking it to a trusted workshop. It turned out to be a bad fuel pump connection. Honestly, sometimes it's worth just letting the pros handle it, especially with the hybrid system involved.

Okay, I appreciate the advice. I think I'll bite the bullet and take it in. I suspected a defective fuel pump but was hoping it was something simple. I took it to the shop, and you were right. The cable connection to the fuel pump was defective. Repair cost me 95€ Thanks!
