1998 Dodge Ram fuel gauge

It has 2 possible solutions 1) fuel sending unit is going bad which the tank has to be dropped to change, 2) you have a bad cluster panel. Hope this helps

i would charge the battery then test the alternator ,low voltage could be the problem

Check fuse No. 9 (10A) in the driver's side kick panel fuse box. But if your other gauges are working (speedometer, tachometer, low oil light, etc.) then it is possible that when you jumped the battery you inadvertently reversed the cables and created a reverse voltage. This will impact some of the vehicle electronics. If you feel this might be the case, you should test the cooling system temperature sender to see if it failed. If it did, you should suspect that the fuel gauge drive circuit located in the instrument cluster is also failed.

you are low on oil in the engine- brake hard and watch the pressure gauge it will drop also---you are at least 3 qt's low.

Put gas in your car and check your tire pressures. If your fuel gauge just "Jumped" suddenly to empty, you probably have a bad sending unit in the fuel tank.

Gas gauge jumping around usually implies fuel level sensor in tank is going bad...Usually if the gauge in dash is going bad will read empty or at various positions depending on fuel level in tank..Electrical short problem in gauge usually affects other gauges in cluster

The Variable resistor in the fuel gague sender unit is worn down, which happens to all vehicles over time. Just replace it, and you should be fine.

Check the ground wire, could be corroded.

I have the same problem on my 2003 Dodge Ram 2500 5.7 Hemi. Also the gauge is sometimesslow to register after filling. Maybe 5 minutes.My neighbor has the same poblem with his 1999 Durango? I think this is a job for a recall.

Replace the alternator if it's output is too low the gen light will come on,could also be loose or dirty connections at alt amd bat
