No, it is not.
I doubt it.
Look for a bad grounding wire. If the fule gauge sending unti is properly gounded, it should send the signal to the fuel gauge, make sure the fuel gauge is grounded. You may have a bad fuel gauge.
Bad dash ground.
The gauge would be in the dash, so yes.The sending unit (float) is available separately from the pump on most vehicles.The gauge would be in the dash, so yes.The sending unit (float) is available separately from the pump on most vehicles.
Answer 1:on dash you have oil temp, rpm, and speedometer. On the lower panel you have voltage so you know if your alternator is working right, oil temp "this one is usually more acurate in my expiriance, and oil presure.Answer 2:In the instrument cluster, there is a coolant temperature gauge (not oil temp) and, obviously but not mentioned above, a fuel gauge.
first thing is to work out which part is at fault? I would start with dash gauge, find wire at fuel tank which goes to gauge, earth this wire out to body while having friend watch fuel gauge, if it goes straight to full it mean dash gauge is good but sender unit in fuel tank is probably at fault. Go to car wreckers for s/h part.
If you mean the " E " at the bottom of the fuel gauge that means the fuel tank is ( Empty , that there is no fuel left in the tank )
buy an aftermarket harness at LMC truck and connect it to the outside of the fuel sending unit and into the dash fuel gauge. make sure your fuel pump has good ground. 16.95us last I checked.
possible fuse or bulb in dash. or worse a loose wire/rat bit a wire.
If the digital dash lights up but shows no numbers for the speedometer on a 1989 Thunderbird LX, it is possible that a fuse is blown for the speedometer and the fuel gauge. There is more than one light in the dash for the speedometer.
There could be a few problems....wiring issue, the gauge in the dash has gone bad, or the sensor for the fuel float is bad, id check wiring and the gauge first because sending units are expensive and can be a pain to change
the float that measures the fuel in the tank may be stuck. or the gauge in the dash may be messed up. pay for an hour of mechanic time and have them take out the float and test it with a volt meter.
