While highway driving 2 days ago, the engine just stopped running. When I pulled over, the windows didn't work, the headlights didn't work, the interior lights didn't work, and the fuel pump wasn't getting any electricity. The engine will turn over, fart and shut off but will not run.

Hi,

Does anything electrical work other than the starter motor? Have you checked fuses for the non-operational electronics to see if there is power both to and from them? If not, do that.

Here is a link you may find helpful:

I dug through the power and ground distribution schematics. I don't see any correlation between the things that you mentioned as far as grounds. So, that leaves power. They get power from different fuses, but the fuses get power from the same power source. That is why I'm asking about the fuses. If they don't have power to them, we need to work backward to see where the loss is.

Let me know.
