Normally when I fill my gas tank all the way the screen on the gauge would say 200 miles until empty. Now it only says 77 miles until empty. The needle is on full and everything. Its as if my tank got smaller. Please help

If you get under the vehicle and look, it's a saddle tank. There is a part of the tank on either side of the drive shaft tunnel. I have no idea how they both get filled up. But I have a feeling, whatever problem you are having is due to this design. I'm sure someone with more knowledge of the system will post eventually, just keep an eye on the forum.

Are you sure it's not just the dash that's wrong? Basically, do you only have 77 miles or 200 miles? These things come with a 16 gallon tank, how many gallons were on your receipt from the station?
