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 component Y3/9n4 is shorted or damaged internally this can short out a data circuit in some cases and cause the no start issue you see here and can be common.If they have diagnosed and tested this properly and know for sure this is what needs replaced then I would have this replaced to see if this resolves the issue.

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
