soooo...... i dont need to have a gmtech2 write the vin on it???

 

Nope, not if it came from another '09 Cobalt, try it and prove me wrong I guess.

 

well

well i did 2 on offs and then stupid me goes back out to see if the light went off and opend the door. now the light is off and if i unplug the pcm and put stock in ran around came back put in the other 09 pcm and it does nothing???? no light or anything it does say i have to change oil soon tho lol. if i turn the key i hear im guessing the punps and thats it.???? is their a way to reset it

 

When I put my spare in all I did was switch the ECU and turn the key on . Got a bunch of dinging .Turned it off and it started right up the second time I turned the key.

 

IF you look up the Relearn procedure you can't open the door

 

i know but how do i go about doing it again???

 

Pull the battery lead off for 10 mins then try again?

 

ok i was ganna try that but had to go to work but today i have off so ill do it when my girls get up
