I suspect the fuel relay... could have been jarred or the circuit board may have cracked during accident.
Pull the relay... remove the cover and examine closely the solder joints where the pins of the little contact points are mounted on the board. These little units are relatively heavy for the printed board because they contain an electromagnet. The solder can and often does crack where the pins are soldered to the board.
If so, solution is to resolder the pin to the board.
