remote starter not working by data

Question

I have a 1999 jeep grand cheroee with no stock alarm also Have a cool start RS00-G4 and fortin INT-SL+. I have flashed the INT_SL+ to the latest firmware and programed step 17 of the cool start to start by 3 presses of the OEM lock button. Nothing happens. I think everything is wired right and the programing went ok as far as I know. It will start if I touch the green start wire of the cool start to ground when programed that way but not by the data bus what could be wrong?
