the 4 wires in the connector/plug in the quarter panel, 2 are for the gas gauge and 2 are for the pump
did you try jumping the power to the fuel pump in the diagnostic port under the hood?
no power to the fuel pump?
check the connector in the driver quarter panel, it is below the jack mount in the rear cargo area,
or
see the wires going into the quarter panel behind the mudflap, remove the rubber plug and pull out the connector
6 point sockets are your friends
from the few pics, the body appears decent, no big rust holes even in the rear quarters
my wifes cousin did a similar rally in Oregon? a couple years ago, find a beater, get it running and have fun. It wasn't the mileage you guys did but it was several hundred...
it was last registered in Gallatin county MT, Bozeman area.
nice find
nice hood prop.
drain the gas and drop the tank for the fuel pump,
get a Denso pump around $100 bucks
