That is the next gen after mine so I really shouldn't comment. However... on mine there is a cable from the accel pedal to a little potentiometer-like thing that senses the pedal position. This sensor on mine is located in the engine compartment in front of the brake master cylinder. On that car, I don't know. So I would first check to see that the cable is connected and the connector is connected. It seems odd that pushing the pedal has NO effect on anything.
