Q: Car shuts off while going over speed bumps.

asked by on

My car starts, but shuts off when I drive it over a speed bump. It will turn back on, but has shut off completely while driving.

There may be a loose connection somewhere in the electrical portion of your fuel system causing the fuel pump to shut off. The relay may also have gone bad and the bump causes the internal metals to ’weld’ themselves back together to recreate the connection. I would recommend having the wiring and relay for your fuel system inspected by a professional.
