The invention discloses a device for preventing a vehicle driving before pulling out of a fuel gun. The device comprises a storage battery, a fuse, a wire, a starting switch, normally open relays, a starter, an oil gun detector and a vehicle-mounted controller. The normally open relays comprise a first normally open relay and a second normally open relay; one end of a coil of the first normally open relay is connected in parallel between the storage battery and the starter; the other end is sequentially connected with the oil gun detector and the vehicle-mounted controller in series; one end of a switch of the first normally open relay is connected with a coil of the second normally open relay; the other end of the switch of the first normally open relay is connected in series between a starting switch and the vehicle-mounted controller; the other end of a coil of the second normally open relay is connected in parallel between the storage battery and the starter in parallel, one end ofthe switch of the second normally-open relay is connected with the starter in series, and the other end of the switch of the second normally-open relay is connected between the fuse and the vehicle-mounted controller in parallel. The device is simple in structure, the linkage type structure is adopted, and the danger that the oil gun is not pulled out to forcibly drive is effectively reduced.
