Nissan hacker cold car throttle didn't respond.

First of all, you can check whether the accelerator pedal is normal when you refuel. If it cannot be opened normally, first check whether the throttle sensor and throttle line or accelerator pedal position sensor are normal. If it is difficult for you to open it, you need to check it. Air intake system sensor. And the oil pressure of the fuel. I hope my answer can help you.
