Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Yes sir, we checked all the fuses they all seem to be in right shape. I called a locksmith who deals with this sort of is you he said he could not get in with his computer something about and taught the shut down. I was wondering if you think it's possible a brain box would be blue and if there's anything I can do cheaper than taking it into the shop? I'm barely making it as it is these days. thank you for your quick reply.

When you turn the key on and try to crank the engine over does the security light flash? if so this guide will help us:

Can you please shoot a quick video with your phone so we can see what's going on? that would be great. You can upload it here with your response.

I just replaced the battery! I removed off my parts car the fuse box underneath the hood replaced every fuse still won't start.

Thanks for the video but it sounds like the timing chain has let go. Lets pull a spark plug out and do a compression test you can get a gauge from the part store for free (they will lend you one) to confirm the failure. This guide will help:

Please run down this guide and report back.

I had the Nissan dealership diagnosed my car this is what they gave me! I have a buddy who told me Nissan was just trying to pump me for as much money instead of telling me the easy way to fix it resetting the ECU computer system. what do you think?

These can be caused by a timing belt being off one tooth. Can we do the compression test to confirm or remove the timing belt cover?
