Hi,

Does anything electrical work? For example, does the horn or brake lights work? Do the headlamps work?

Take a look in the underhood fuse box. Check the heavier gauge fuses to see if any are bad. See pic below.

Also, are you certain the battery is fully charged? Have you checked the battery terminal connections to make sure they are clean and tight?

Take a look through this link and let me know if it is something you can perform:

Also, if there is a spare key, try it. It could be something with the immobilizer shutting things down because it doesn't recognize the key for some reason.

Let me know what you find or if you have other questions.

Take care,

Joe
