Last night when I was trying to replace the thermometer in the 2.0 LSJ engine I ran upon some difficulties. First I disconnected the cam shaft Sensor housing and move that off the side and then I proceeded to go to the thermometer. I took off the thermometer housing then took out the therm and replaced it and bolted everything back together just like I took it apart. I slipped the cam shaft sensor housing back on and re connected 2 harnesses.. I disconnected the negative waited 5 mins then re connected it.. Now the cobalt will crank but not turn over to start and fire up.. Any ideas of why this could be happening?! What can I do to figure it out?
