Friend has a 2000 Deville with the Northstar with 77,000 miles. He got broadsided on passenger side right at the pillar. Car totaled. Now we can't get car started. Getting no fuel. If we spray starter fluid in snorkel, car starts up so we know its fuel. We put 3 gallons in tank to verify that car has gas. He does not have owners manual. Is there a fuel cutoff switch that got tripped or does anyone know of a fuse or fuel pump relay I could check and the location? Before accident, car ran great.
