I have a Ford F-250 2002 model. Lat night I went to wrk and was late getting off. When I came hom ethe tank was low and said it had 11 miles to empty. I started the truck. It started fine. Went inside to let it warm up, but upon return it was dead. I wen t and got 2 gallons of diesel and tried to tur it over. It whined and knocked but would not turn over. No check engine lights or anything come on when I turn the ignition to the on position, but when trying to satrt the glow light plug is lit up. Is the truck out of fyuel? Or is it something else? If so, how do I get the truck re-staterted if irs merely ran out of fuel?
