So i am in desperate need of help. I have a 2007 Cobalt SS. Had a bad battery, replaced the battery and one of the connectors. Alternator was failing, replaced that to. Starter switch was going out, replaced that as well. Now the car will not start or even try to turn over. Not from a pop start, or regular start. Car gets power, I can turn on the radio, heat, roll up windows etc. Just will not crank at all. Also when I have the key in the on position power steering and low fuel pop up on my dash and I have never had power steering pop up, and I know it has gas in it. Have went through all fuses and relays and they all are fine. I am at a loss and want to just push the car into the river. Any help that anyone can give?

 

My car is doing the same thing right now and I was about to make a post here about it. In your car it could clutch position sensor, if you look under the dash it should be a small push switch that is on top of your clutch petal. If you want to see if you can get it turning. Take the CRNK relay out, put a jump wire between the corners and it should turn over the starter. This should send a signal to the starter and solenoid to turn over. Make sure the car is in neutral this will work regardless if the clutch is down or if there is any one turning the key, but it wont start the car. If you do this while someone else in the car turns the key, it should fire up.

 

How'd you know alternator was failing and starter switch going out? Like what symptoms prompted you to replace these parts? If the car started fine before you replaced parts I would double check every connection you touched because most likely it would be something you didn't quite get connected back together right. Car should start from "pop start" even with a bad starter switch or starter itself. Are the dash lights all coming on like they are supposed to when you turn on the ignition?
