After being driven normally all day, the car all of a sudden wouldn't crank properly after being parked for a few hours. The car needed to be towed to a car shop. According to a local mechanic, the back seat pressed on the wiring that, in turn, burned up the electric panel and the fuel pump. Due to this, the electric panel and the fuel pump need to be replaced.
