what is the problem?

you dont say what car you have. but modern cars usualy have a fuel isolation switch, can be found under the bonnet, under dash or seat. the reason for it, is that if the car is involved in a accident even a minor knock this switch isolates the fuel from the engine to reduce the chance of a fire starting. maye you activated this switch when bumping over the kerb, check your drivers manual on its where abouts if it has one.
