Installed Overkill PCM in my 04 Grand Prix GT2. Unable to start the car. Tried doing the security relearn for 10minutes on, 5 seconds off 3 times. Nothing. I've also tried the 5 seconds on 10 seconds off for one cycle as recommended by will at Overkill. All doors, hood, trunk, were closed at the time. I reached in through the window and did the security relearn. No luck.
Also removed after market remote start unit just in case that was causing it to not relearn since the remote start has its on Key. I then did the security relearn still nothing. DIC showed Theft Deterrent warning. I emailed will again waiting for a response.
Does anyone have any ideas what the problem is?
