As i was driving back home, i heard like a faint pssh sound and my gas pedal stopped working. I got to the side of the road and turned the car off. Tried to start it but it wouldnt, only clicks, like there is no fuel but i have half a tank. I recently took off my blockoff plate and bov so maybe i knocked something loose and it fell off when i was driving? before that i had an oil change at the dealer.

My bro says it could be the fuel pump.

 

oh its an 08 MCS

 

The gas pedal is electronic (fly by wire) so there's probably an electronic doo-hickey attached to it that went bad or got disconnected.
