I just replaced the engine in my friends 2008 cobalt. Got everything all hooked up all fluids put in. New battery, hoses, belts. Went to start it and nothing. Has plenty of power but in run when trying to start it all lights go out and nothing. Will not turn over at all. Rechecked all the plugs and wires and everything is hooked up right. Do these vehicles have some sort of security system that makes them not start? Any other information would greatly be appreciated.

My cooling fan does not turn on. I hooked up wires to the fan and it turns on, I checked the fuse, the relay and put in a new sensor. It still will not turn on, even at 205 degrees. If I pull the wires out of the sensor it runs but won't turn off. 2 Answers

I checked the fuse, the relay, and put in a new sensor. The fan runs all of the time when I unplug the sensor but will not come on when I plug it back in no matter how hot it gets.

2006 Cobalt all of the sudden I lost power steering, cruise control, power windows, windshield wipers. The a air bag light came on and the middle of the display on the dashboard (I.e. where the check in light and seat belt light is) is out. The car has driven fine until I started this morning. Now my driver's side window is stuck down and it's barley drivable. I went to a Chevy dealership and they say all recalls on the car were fixed in 2014, oddly enough including the ignition, power steering, and air bag ... I asked why it was all broken again. No clear answer. Can someone please help me 3 Answers
