well the obvious thing would be the wiring
to the fuel pump. between the debris and the possible tire pieces, it would be very possible that a wire got busted or a connection disconnected. crawl under there with your trusty maglite and have a look, reach and follow the wires to and from the top of the gas tank. if you find a connector off, you have found the 'reset'
now, what kind of debris blows out
two tires. yikes. that doesn't sound like any fun....
