fuel gauge always reading empty "Low Fuel Warning" even if the tank is full. The auto computer which displays how many miles you have left before refilling also reads "Low"

Hi there,
I would be checking the tank sender unit, if you earth out the tank gauge wire with ignition on, the gauge should go to full, if this is so, the sender in the tank is faulty.
