    The mpg and fuel gauge fluctuating is related to the speedo not working. The instruments use the speed signal to determine when the cars moving and make the fuel gauge 'lazy' so it does not fluctuate under hard cornering. The mpg has stopped working as it can't calculate how fast your driving. First port of call is to check the connection to the speed sensor on the gearbox (3pin connector towards the back of the box) they have a habit of corroding, if that looks ok, chances are your speed sensor has died and replacement is necessary.
