hello please help i have a e36 323i with this problem. when i bought the car last month what i was not told the fuel gauge was stuck on 1/4 of a tank so i first thought was the fuel gauge was stuck as it stayed the same with the ignition off so i bought some new ones done the test you do by holding the reset button with the key half turn and all move fine so they work. but now the fuel stays empty with the tank full so i taken out the left hand fuel sender and found a wire had broken off the sender unit so replaced it with a new one and still no reading. i was told to short the connection out as it should send the gauge to full but no joy. so is seems i have no power going to the sending units as i tried both each side of tank. could it be a fuse i checked all the ones in fuse box by the engine and all look fine so are there more fuses in the car i cant fined please help?????????????
