I had just driven the car on a 2 hour trip with no issue. I drove that trip in the morning and that afternoon I went to start the car and the starter was going but the engine wouldn't start. I lifted the back seat to find an awful smell coming from the fuse box. I pulled the fuel pump fuse to find it singed. The vehicle will be needing a new fuse box and I'm still waiting to find the part.
