G morning all, just finished installing a compustar into a 2004 grand prix. problem I am having is although I have the compustar programmed to unlock before start, and relock after start and shutdown,It does not relock after the car starts. I have all, lock, unlock, arm and disarm wires connected and a isolated relay from the rearm wire to pulse the drivers door to shut down the rap. just wondering if the vehicle is not allowing it to relock while it is running and getting a door pulse.
Any ideas or help would be appreciated.

You need to use a relay to open the door pin pulse wire while running. Use ignition and the negative out when running to power the relay (terminals 85 and 86) Cut the door pin pulse wire from the remote starter and connect to terminals 87a and 30. The car thinks you are going to lock yourself out with the engine running, so it won't allow the doors to lock.
