but I want to make this one different. I have been reading all the fuel gauge posts on here and two things are clear to me. 1. there are a ton of smart people on here, 2. that throw out ideas all at once. All the great info is so hard to keep track of. My request, can an expert please take a shot at making a check off list on how to diagnose a non functional fuel gauge? Seems like there are three culprits in order of probability, 1. ground wire. 2. sending unit, 3. fuel gauge. If all the experts can agree on a check list then we might be able to make it a sticky thread and help everyone who seems to never be able to figure out their fuel gauge. Until then, I will just fill up every other time I drive.
