i was driving kinda slow about to turn, and i pushed on the gas and it did nothing, the car was still running but i wasn't going anywhere. Now it won't start. its throwing out p 0340. but we changed all the sensors, and its not the fuel pump. We don't know what els to do, we have tried everything.
Here is a link to the video. maybe you can tell what it is.
