The trouble is probably in the first line above.  "I changed the sending
unit."

There is an issue with Vanagons over the correct sending unit. I can't
remember the details but I remember that this problem exists. I would almost
bet you wound up with the wrong one, especially since you didn't do anything
else at the time.

Be aware of this problem, and see if you can find out the details and nature
of this conflict of which is the proper sending unit.

Good Luck.
