I stopped to fill the tank today ($3.39 a gallon!) and punched the trip
meter to take it back to zero.  I wrote down the mpg from the previous tank
and noted it seemed a little low.  After driving across town, I looked down
to see that the odometer hadn't changed and the trip meter was still on
zero.  The speedo is working though.  I tried the reset button a couple more
times - once at a stop and once while moving.  No change.

Question one - what is the problem?  Question two - how do I check it and/or
fix it?  Thanks.
