Thanks for all the input, I really appreciate it.

To clarify a bit -- the dealer first replaced the fuel level unit which is part #5127430AA and a fuel pump seal #5101733AA (they said they were bad, but it did not help the car to start), then replaced what they call a relay (I call it an engine control module) Part #5099007AA and the car started and runs but the gas gauge does not work.

In a 2006 with 15,000 miles (I live in Naples FL. where people often live part of the year and let cars sit for long periods) the fuel pump seal could have been bad. But it seems to me from what I've read on this forum the problem may have been the relay (maybe a solder point) to begin with. I still think I should be able to get a gas gauge to work without tearing up the dashboard. Anyone disagree?

Thanks again,
Greg
