What fuse can cause a car not to start?

Many cars have a fusible link inline with the main power cable from the battery that can blow and cause these symptoms. Some cars have a main relay that can blow instead or in conjunction with a fusible link. Many modern vehicles have a fuel safety shut off switch. The latter is a switch linked with a shock sensor that shuts off your fuel pump if you are involved in an accident ( or hit a curb ). This type of switch needs to be reset in order to allow your fuel pump to function again.
