You don't get power to those leads, it all works off of a ground signal.

if you don't drive it far then let it sit there will be condensation inside the exhaust. The next time you start there would be a little white smoke until it warms up some. How much smoke are we talking about?

running at 8 mpg means there's something wrong there. Codes are the best place to start. How many miles are on it?
