Hi,

When you connect the scanner, does it power on? If not, start by checking fuse 46 in the under-hood fuse box.

I attached a pic below showing the fuse location. Here is a link you may find helpful as well:

Next, in most cases a crank no start is the result of either a fuel or ignition related issue. See if it starts if you use starting fluid. If it does and then stalls, we know it is fuel related. If there is no change, we need to check for ignition spark at the spark plugs.

Here is a link that shows how that is done:

Try this and let me know the results.

The scanner doesn’t power on. Here’s a diagram of the fuse box under the hood.

Hi,

That's the correct pic I put above. If you look below, I copied your picture and circled the fuse to check.

Let me know.
