My father had his battery died in his Tahoe listed in the description. I replaced it and it started fine, but the idle seems to be surging. I marked this up to the ECM reprograming and thought nothing of it and left. He did drive it one day without mentioning any issues. The next day he couldn't get it to stay running. It would turn on, crank right over but as soon as it started running it would stop and the dash would flash like someone is touching the battery cable on and off the post. I will say that the key he uses is not a PATS key. I have removed the plastic cover looking for a bypass loop that someone may have installed but nothing seems to be out of the normal there ether. If I disconnect the battery and connect it back up, it will do the same thing. Once it has shut off, it will not crank over. I also notice the security light does shut off. I even tried to have the system "Relearn" the key with the left on for 10 minutes for three times...no work. Is it common for a bypass installed on PPV issued Tahoe's? I really want to get his Tahoe back up and running again, but at this point am at a loss.
Thanks everyone.
