2000 Oldmobile Alero Remote start intermittant

Thanks for all the input.  Believe me, I tried utilizing all the troubleshooting codes and testing everything possible in the diagnoses of this problem.  It turned out to be a bad relay in the Autocommand unit.  Though the jumper was set to energize Ignition 2 during On and Start, it was not energizing it during start.  The unit was working intermittantly when there was enough fuel pressure in the lines to start the car long enough, and then catch when Ignition 2 finally did activate.

Unfortunately, this unit was supplied by the customer, and purchased a while back.  In order to save myself some work, I just installed an external relay off of Ignition 1 for proper activation of Ignition 2.  Live and learn I guess.  Again, thanks for all the input!
