Does the check engine light come on at all?

Have you checked for codes in the computer?

Does the engine crank over and not start or does it not crank over when this happens?

Expert:  Amedee replied 1 month ago.

So it does not crank over right now?

May I start by getting your VIN?

Thank you for that information. Have you checked the inputs to the starter relay?
Customer: replied 1 month ago.
Expert:  Amedee replied 1 month ago.
I would recommend to do that next. The relay needs to powers and one ground to operate. This of course is with the key in the crank position, so you will need an assistant to help with this. Let me know!
