1. Check the battery in your remote start system. If the battery is low, the system may not have enough power to start your vehicle or keep it running. Try replacing the battery and see if that resolves the issue.
2. Check the wiring connections for the remote start system. Make sure all the wires are properly connected and that there are no loose or damaged wires. If any wires are loose or damaged, try reconnecting them or replacing them.
3. Check the programming of the remote start system. Make sure the remote start system is programmed correctly for your vehicle. You can check this by consulting the owner's manual for your remote start system or by contacting the manufacturer.
If you've checked all of the above and your remote start system is still not working properly, you may need to take it to a qualified technician for further diagnosis and repair.
