My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

This fault here can very well be due to the after market system installed.Usually what has to be done is to have the system removed completely and the vehicle wired back to factory to resolve this issue here.Once this is done then it should start up and run properly.You will have to locate the after market alarm control unit ( usually located under the drivers or passenger side dash) and this would need removed and all factory wiring put back the way it used to be.

If more help is needed, use the reply tab to continue our conversation.
