Asked by Apr 19, 2016 at 02:28 PM about the 2006 Chevrolet Cobalt LS Sedan FWD

Question type: Maintenance & Repair

I went to crank my car this morning and nothing happened.  All the electronics come on as well as the lights.  There is no dimming when I try to start it.  I had the battery tested (not even a year old) and it came back reading good.  There is no click when I start it.  Nothing happens.  What should I check?  Thanks.

If all your connections are tight to the starter and your battery is good you probably need a tow truck and a good mechanic. It's impossible for us to trouble shoot something like this with no real information.

Thanks guys. It was the ignition switch and starter relay. I do have a good mechanic that I can trust. Those seem rare in my area.

my daughters 2005 cobalt is doing the same thing. It won't do anything when she tries to turn the key. Battery is new, lights and everything work fine. The car sat for 2 days then for the hell of it we tried starting it and it started right up. The next day she drove it, parked it and then when to start it and the same thing happened. Any ideas?

Scan it for trouble codes. Check that all grounds are clean and tight and that battery connections are tight. Ignition switches and their associated solenoid and relays can fail. Have those components checked by someone with a good understanding of automotive electrical systems. Troubleshoot first. Then spend money on the repair.

That doesn't sound like advice from a technician. If its the starter relay that's at fault it would simply need to be replaced.

Dry out your car. Fix the wire and figure out where the water’s coming from. Do you have a sunroof. They are prone to leaking or having the drains get plugged. Also how is the car parked during wet weather. I find if I park mine facing uphill in the rain I end up with water inside. If I park level or downhill it’s fine.

I had the same problem so I checked all the fuses and the only one that was blown was for the cigarette lighter so I replaced it and now it starts fine.

Same problem. New starter, new battery, checked the starter relay by swapping in a new one. Don't have a mechanic I trust who does electrical. It was only happening on occasion and restarted 20-40 minutes later, last night it took an hour and forty minutes. Used to be a long time between recurrences, now it's happening every day.

No trouble codes, nothing. No lockouts.

I found my problem, probably won't help anyone else. Apparently the previous owner mounted a starter kill switch to prevent theft. When he went to sell the car, he removed the switch but not the wiring, and he used cheap aluminum wires. When the wire heated up, the car would not start, and when it comes down, it would.

Just had to remove the wire.

Glad you found it. Messing with the wiring on modern cars is always risky. The electrical system is so sensitive to everything it takes very little to upset it.

Alrighty, I'm having the same issue. Replaced battery and new starter as well. Turned key let it do its cycle then go to start and it just clicks like 3-7 times then stops turn key off remove key then put the key back in repeat with same results just clicking sound then nothing.

Sounds like a bad ground or power connection somewhere. Double check everything you’ve worked on to make sure you didn’t miss one.

I have a 2009 cobalt no crank no start new battery checked all the fuses any ideas. Not doing anything no clicking can hear fuel pump coming on have power to the starter scratching my head on this one thanks!

I'd suspect the starter itself if there's power to it and the fuel pump is cycling. Take it off and have it tested before you buy a new one though.

I have a 2007 colbalt that will not start. It will turn but never fire. I have checked the fuses, starter, battery, power to the injectore(with a noid light), and I have checked all the wiring I have came across. I had an error code of u0073 that is now gone and in its place I have u0101 and p1682. Any ideas on what to try next?

I have checked the fuse going to the battery in the trunk. I have also checked that I have fuel going to the injectors. I do not get a security light at all and my check engine light is on. Still no solution

Check the fuse in the trunk next to battery,or check ignition switch electrical part,also take your vin number and call the dealer talk to a service advisor give them the vin number to see if there any recalls or campaigns for your car.

My father in laws Cobalt had an issue in the engine compartment fuse box. There is a wire in the upper left corner that when wiggled, it would make the car start again. Apparently there is a short there, possibly in the connector.
