A bad sending unit in the gas tank.
i have sort of the same problem on my dodge 2000 the temperature gauge recently went out and i replaced the sensor but the gauge always reads 0 your not alone with this one...
There are several things that can cause your 2000 Hyundai gas gauge not to work. The most common cause is a loose or corroded ground wire.
Bad gauge and/or coolant temp sensor The coolant temp sensor doesn't control the gauge. There is a sensor in the head on the driver's side that controls the gauge. It is fairly easy to get to, probably one of the only things on a 4th gen. lol
Simple fix is usually a new oil pressure sending unit. It could be unplugged or the line broken somewhere. If none of these are the case, it's probably a bad gauge and will need to be replaced.
