The fuel gage on my 1988 Eldorado always says empty so I need to use the trip odometer as a fuel gage and reset every time I fill up.
The previous owner mentioned that the fuel tank was replaced, and he thinks that the gage was not working right after that.
The manual has a flow chart called "Erratic Digital Fuel Gage" and the first step is to "disconnect the fuel tank sending unit connector". Do I need to remove the fuel tank to do this? I've read elsewhere that to replace the fuel tank sending unit, the fuel tank must be removed on Eldorado's of this era, but what about just disconnecting the connector?
