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. If anything after market has been wired into the vehicle at all this can cause an issue with some wiring circuits in some cases needing either re wired differently or removed all together.If this is found to be o.k. or no after market components installed this may be an issue with the ignition switch itself as I have seen fail before needing replaced.These will have to be checked/tested further to see if there is an issue needing repaired or replaced. If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.Thanks Pete
