I have an 05 cobalt... manual.. 2.2l and I went to start it after bowling for an hour and my electronics went haywire... all my warning lights were spraticly flashing then it turns into my check engine light and antitheft light flash super fast... at the same pace as the relays that are also clicking like mad... fuel pump and crank relays under the hood are clicking... and it sounds like there is one more under the fuse box too but idk how to get in there... there is also something clicking in the interior fuse panel... pulled every relay and the ones I mentioned before were the only ones that had an effect... I unplugged the forward wireing harness from the interior fuse panel and that stopped it all but if corse its back when I reconnect it... Also several hours before it happend I thought I smell faint burning rubber (now im guessing it was wire insilation) from the car but I was in a hurry and the car was running fine so I let it go... drove about 120miles... stopped and started it 3 or 4 times with no problem then it spazed out... it's dark now if this is not enough I will post a video explanation tomorrow... it's close but not quite like any of the problems I have found on the internet... closest to the TCM ground issue but I tried grounding it to no avail...

 

Also I have no response from my OBD plug

 

you have a manual transmission, so you dont have a TCM. tcm stands for transmission control module, it controls the automatic transmission.

to me it sounds like low voltage. check your battery connections and check the voltage sitting and while cranking (you will need a 2nd person to help). its quite possible your battery is just junk.

 

That did it... I tried jumping it before and it didn't work so I figured it could not be a battery problim... still not sure why that didn't work.... anyway thanks for the response, I'm glad I didn't take it in and that it was not a big deal... I was wondering what a TCM would do for my standard.... guess that's why mine looked different then the ones in the videos
