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.

If the key did not come from a dealer ordered in by the vehicles VIN number then the key is incorrect and needs replaced with one ordered in by the VIN number.If it was ordered in and this issue occurred after the key was replaced you may need to have it programmed since it sat for so long.

The other issue I have seen is a faulty fuel pump needing replaced.I would have the fuel system tested if needed to see if this is the cause here.

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
