Lastnight when I was on my way home my car broke down, I was only doing 55 in 5th. All I know is it will crank but wont fire, sparks came from under my car that sat and burned on the road, and when I popped the hood there was a burnt smell coming from the driver side. All the belts that I can see (3 of them) are still good. I need help figuring out what could be wrong with my car. Thank you for reading.
