2005 Cobalt 2.2 no start (machine gun)
Hey guys.
New to the forum. Question about my no start. Car ran fine over the last while. It sat for maybe 5 days. Go to start it and it acts like the battery is dead. like we left a light on or something. which we didn't. Battery is 6 months old. I go to jump it with a known good red top optima from our audi and when you turn the key over it sounds like machine gun fire. Like the start motor is trying to engage but its not catching. no matter where i ground the negative side of the jumper nothing catches and all i get is this machine gun fire sound of it trying to catch. I've tried using different keys. OEM and non OEM. I did notice that the instrument cluster will say reduce engine power and the check engine light is now on.
If my altenator was going wouldn't I still be able to start it and then watch the voltage die out/fade with a multimeter? I can't even get it started to test. No idea what to check. I've gone through the fuses on in the engine bay and the 2amp starter fuse in the cabin. all seem to be fine.
When I turn the key to on/ignition it will try and start the car and continue the machine gun sound until i turn the key off. At the end of the video I leave it for a while and it just struggles with itself. Really not sure what to do or what to check.
any ideas? Vid attached

Ground straps seem to be fine. I took a wire brush to the starter terminals and other ground locations in the bay and issue still presists. You can hear the solenoid getting power as it continually attempts to come on. however there is no draw for the starter motor itself. Every time I start the car i'm trying to jump it as I know the battery doing the jump is great with a ton of cranking amps. what is the procedure to determine if the starter is bad itself?

SO i put 12v to it and it started for a half second and died. did this MULTIPLE times. the security key on the dash was lit up. So now i'm thinking its Ignition switch due to:
-the ignition switch regulates voltage to starter motor
-ignition switch also works with the security system as well.
Thinking its time to replace the switch.
Thoughts?
