For now I would remove the sliding door wires just incase thats the root of the issue.
Bypass side please make the following changes:
Turn off option D2. This should not be on and can prevent starting. If your vehicle is equipped with a OEM alarm, you are supposed to connect the orange disarm wire from the 20 pin as shown in the diagram and enable option D5.
Remote Starter side please make the following changes:
Set option 6.2 to 6.1
Set option 20.2 to 20.6
Once these changes are made test the system and see if it'll remote start.
If it is working at that point, its just configuring your options for the sliding doors properly...which arent set up properply at the moment.
