I have been trying to install a Codealarm model F50/F55 in this 04 Grand Prix. After testing the connections and 2 brains, I have found nothing. All of the connections test correct (and yes the correct pink ignition wire is being charged for those of you who know about that.) The unit when activated will charge the accessory wire as to turn on the said circuit. When it is time for the starter to crank, there is a split second sound as the beginning of starting, but it does nothing after that...the unit has a bypass module that tells me it has been programmed correctly. I am at a loss for words. My experience is with DEI and code is different. Please help.
