Was driving down the road and hit a bump and the radio shut off and came back on. Next day was driving down the road and went across a rail road crossing and radio shut off and car shut off. It cranks over but will not start. After looking at it more I realized my fuel pump is not turning on. What would cause my fuel pump and radio not to work? I shook the wires in the fuse box under the hood and on the side of my dash to see if it was something with a wire since a bump made it shut off.
