hi, I recently changed the pcm on my Malibu 2009.. is there a way to activated to my vehicle so it will start? it was already program by a technician with a tech2 computer and it worked, but then I removed the pcm because I was going to put some plastic covers back into the conections and forgot to disconnect the battery first.. then I connected the pcm back and the car didn't start
will I need a tech 2 computer to reactivated? or can it be done manually? any help will be appreciated, thanx
