This was the best straight to the point information to narrow down the issue. I myself say the best so far that I have ever seen and explained and shown clearly on what everything did. Awesome job. And he didn't show anything that would confuse you. This helped me find my issue quickly
thank you so much, I bought a $400 cobalt and it's key security worked fine but the starter would not go, bridging this relay meant I could start the car and I put a light switch in to hotwire it on but only when the key is in, you just made the $400 car journey even more fun
You have been very helpful to me. I have another question now. I changed the fuel pump relay. It's doing good! Now I'm having an intermittent start and stall at crank up. Any advice? Also, I noticed since my car came back from the shop, my underhood fuse box wiggles. Is there supposed to be a nut securing it to the coolant reservoir? If so, it's not there. I'll replace if needed
Very helpful thanks, Any insight into way my car would start sometime and no other, no crank. I will always start eventually, but sometime I have to wait around a while. There doesn't seem to be a pattern, sometimes it starts no issue, you can even start it back to back, other times you can turn in off and try to restart and nothing. I'll go try and do some testing with the information you provided here hopefully I can get it narrowed down.
Hey what’s up Up got a 2005 Chevy cobalt and it was doing a whining noise from the starter I bought a new starter and is doing the same thing like it’s not engaging the flywheel but I tested the starter outside the car and it’s spinning in shot out like it was supposed to
What could be the issue if the car is idling for a bit then it shuts off by its self but it’s start fine and everything but it shuts off on its own once in a while?
There's a threaded stud on the front of the motor that gets corroded, there are three wires that have to do with starting it, common problem on Cobalt's, I noticed you didn't mention it, I've seen it happen several times, those wires get corroded and lose contact.
i have a 2010 cobalt that was driving fine no check engine light or anything. drove it got out went to get back into it to leave and no start no crank. turn the key all i get is one click from the passenger fuse box in the center console. i dont hear the fuel pump or anything. the headlights work along with the radio and horn. i need some help ive checked all grounds and cleaned them and installed new connectors. i can jump the starter relay and the car will turn over but not start.
I'm having trouble with my 2005 chevy cobalt 2.2 and its a manual so what is happening is when I insert the key it starts to ding telling me that the key is in ignition then I turn it over to the Acc and the headlights and dashboard lights come on like normal but the radio or dome light wont come on and then when I try to crank the car over it everything cuts out and all I see is the anti theft padlock lite up on my dashboard ive replaced the starter relay but its still doing the same thing so I took the starter relay out and used a paper clip to connect them to points u said too n yes it did try to start and it also jumped at me cause I forgot to take it outta gear I brought a new battery yesterday and its still doing the same thing and a couple months ago my radio in my car started to kinda cut out/got real low when i would turn and then the radio would return to the correct volume n i would sometime hear like a wire poppin coming from the steering wheel column so im sure that theirs a short somewhere n when the first day that my car wouldnt start and doing this i took my battery out had it tested n my battery was from like 11/2017 so they thought it could be a bad battery cause they said it was only at 26% percent so i had them charge it for me for like 5 an half hours picked it up and they said thats its charged up and putting out the 12.6v and I put the battery back in still the same thing and then yesterday i went to try n start it and I had no power at all so I had to jump it just to get enough power so i could pop my trunk to get to the battery so thats why i just went a head n got a new battery ive tried to reset the anti theft but turning the key over and leaving it on for 15-20 minutes and repeating that 3 or 4 times and still the same I bought a voltage tester yesterday to see if the computer is getting power but tbh I dont know how to use tester or what settings to use so if you could possibly help me out I would appreciate it
My purple (small) wire to my starter isn't getting power from the fuse box which as you know, is connected to the crank relay. This results in a no crank/no start since I purchased the vehicle. Any thoughts on where to look next?
I changed my crank fuse and now my 06 cobalt SS , won't start. Should I check relay. Fyi, car was starting with damaged fuse. However I haven't checked the inside fuse panel.
I have a 2005 Chevy colbalt and the run/crank relay is getting hot and the tcm to?? I check the holes where the run crank are and it only lights up on the two holes on the left side on the right there is no light up with the test light? am i suppose to have light up on the right side ? To? A little help would be appreciated.ty
Great video, I jumped the pins you mentioned and the car starts, measured the voltage across the other pins I’m getting about 11volts I’m assuming the computer is ok, I swapped the relay, and tried your other recommendations but the car still will not turn over. Any Ideas?
11 volts seems a bit low.. is your Cobalt an automatic? Perhaps there is a weak connection in the neutral safety switch allowing some voltage thru it but not enough to trigger the relay. The computer provides a ground and a weak ground from the computer could be an issue as well.
Thanks I will try that, by the way it is automatic. I was seriously thinking it was the ignition switch, I didn’t mention that the problem is the infamous intermittent situation sometimes it starts sometimes not, which left my daughter stranded a couple of times.
Why would my 06 cobalt not start after working all day then i come back the next day and it starts with no problem. I drove it home 30mins it sat for about 3 hours then wouldnt start again. It sat over night and started this morning no problem
Hi. I have a 2008 Chevy Cobalt that seems to lose power often whenever i remove the key from the ignition. I have no idea what it could be. Any ideas? I went to have it smogged and they said there wasnt enough data or whatever on the ECU or something like that and that i need to drive it at least 100 miles. That’s pretty hard to do when the darn thing is constantly resetting itself when the key is turned off and pulled out. PLEASE HELP! Ty
my car stalls out at a stop sign so then i put in park and restart the engine and it usually doesn't do it again that day. i heat the car up before driving and i have a heater block for winter. took it to mechanic and of course car woks perfect. they don't want to keep changing things without knowing what might be happening
Interesting, my 2009 cobalt was running well. Two days ago I got in, fuel pump came on, lights on the dash, and lights in the car came on... including check engine light came on, but it would not crank. I heard nothing other than the fuel pump. I will check those relays. Let me know if you have a better idea.
What would you do if your Cobalt stays running for a minute or two after you have taken the key out is that a different fuse or can it be one of these fuses as well?
@@adamgonzalez4393 Yes I had a bad fuel relay fuse, and I swapped it with another until I could get to the auto parts store. If your anti theft is stopping you, I put my key in the driver's side door and unlocked and locked it 3 times. I don't know if it helped, but I saw it in another video.
My I had someone check my fuses, which is where I messed up , and since they messed with it I'm getting a check charging systems indicator. And I'm getting the battery light , and my windows are lagging alot? Does anyone have a suggestion?
When i try starting mine the PWR/TRN relay makes a fast clicking sound. I swapped out the relay with another and it still does the same thing. When i turn on the key nothing happens.
@@ForGabeAndSammy Turn auto-unlock/lock in the DIC off. Press Info + Enter at the same time to get into that menu. Then unplug the door lock switches. Have to go full manual. All that seems more work than forking over $100 for a FOB.

I seen in one you tube video about resetting the anti-theft off the ignition switch finding the ground wire, fused 5 plus wire, and they ignition wire, and I believe the in and out communication wire and he had to fix getting power to it or something by using a pointed insert to poke through the fused 5 plus wire and then lead that wire over to the diagnosis data plug and just clipped it into there and he turned the key over and it went off and was able to start it but when I attempted to do what he did im lost mainly cause I dont wanna mess up anything and I just bought this voltage tester n tryin to learn how to use it or what settings to use so if anyone knows what I'm talkin bout and can help me please help me

Dude I am having the same issue, same car, same year! Did you make any progress?
@@TheRemmell oddly my starter seized without warning. Never had one fail like that.
@@TheRemmell every other starter kinda gave warning. This one just locked up.
Your flywheel was seized? Or a bad starter?
@@TheRemmell the starter locked up.
What would cause my starter to crank with no key in it and cause my ignition to be reversed
What would you do if your Cobalt stays running for a minute or two after you have taken the key out is that a different fuse or can it be one of these fuses as well?
That sounds like an issue with a faulty ignition switch or some badly-done wiring to an aftermarket radio or security system.
@@LehewTech gotcha I think it might be the switch because it just started happening and no new radio or anything in the car.

Pull up the diagram and follow the wires around. Check the grounding cables, too.

Start the car with the chipped key. It will turn itself of. Refrain from locking the doors with the door lock switches until you can get a FOB.
@@christianguzman8228 I did that, and It works, but soon as I open the door whether I manually locked it or not, will activate the alarm again.
