Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

My info does show you have an inertia switch.It is located under the dash on the passenger side.Unfortunately this is the picture I show on this here myself.

This model does not tell me if it is resettable.If it is usually there is a button or switch on it to reset it.This may be a faulty fuel pump causing this here.The fuel pump can fail suddenly as I have seen before with it needing replaced.You would have to have the power and ground tested to it to see if the power signal is missing and if it is then the inertia switch most likely needs reset or replaced and if it has power and ground then the pump is faulty needing replaced.

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 ( should be a link to click on here or above).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

I apologize for the delay as I was not able to get back here yesterday.

Unfortunately my info isnt showing me a clear procedure on how to access it.Have you checked all over under the dash area and passenger kick panel area for it?
