Sequoia hybrid fuel pump issue

I had a similar problem with my 2018 Audi A4. The symptoms you describe were almost identical – hard starts, stalling, check engine light, and rough running. In my case, the issue turned out to be a faulty fuel pump relay. Have you checked the relay and its connections? A defective relay can cause the same problems as a bad pump.

Thanks for the tip! Where is the fuel pump relay located on the Sequoia, and how difficult is it to check? Do I need any special tools or knowledge?

The fuel pump relay location can vary, but it's usually in the fuse box, often under the hood. The owner’s manual should have a diagram. Visually inspect it for corrosion or damage. Swapping it with an identical relay can help diagnose the problem. However, given the error code points to the fuel pump itself, a visit to a workshop might be the best course of action to confirm whether it is just a connection problem as you initially suspected and avoid unnecessary repairs.

Thanks for the advice. I took it to the workshop, and it was indeed a defective plug connection to the fuel pump, just as I suspected. The repair cost me 95€.
