How to disable factory alarm or reset it? the alarm light is not showing up but for some reason it disable the starter so I cannot start the car. The car was parked so maybe about three weeks or so due to lack of having the money to replace the fuel rail system and that they replaced it now the car won't start. it has to be the starter is not engaging because of the factory alarm.
