GMTNation - Installing A PCM (4.2L I6)
It does say when engine engine won't start, leave the key to ON position until security lights goes OFF. But that would kill the battery right? And if battery dies, within 10 minutes or until the lights goes off, will that harm the PCM?
Also, if you're putting the same PCM let's say from being tuned, engine should crank and start correct? Anyone's sharing their experience is highly appreciated.
