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 you havent yet I would check the ignition switch that connects in line with the ignition cylinder and make sure it is lined up properly and is functioning properly with the cylinder operation as this can cause this type of fault here.Usually this wont cause an issue with no head lights but can cause other electrical faults.

Double check and make sure all fuses are good in all fuse panels as well.If these are all checked and found to be o.k. let me know.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated.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

When you lose the dash lights in the start position do the lights return after releasing from the start position at all?
