I have a 1996 NEON that the speedometer and fuel gage didn't work on. the fuel gage will go to full when you fill up but after about 50 miles it drops to empty. I pulled out the dash and redid the solder onthe pins and now the speedometer works but the fuel gage is the same would the sending unit be the next thing to try?[/align]

 

Try resoldering again, just to make sure it was done correctly. If not, then its probably a bad sending unit.
