I have a 2003 expedition EB that will not turn over or do anything!!!!! Went to wal-mart yesterday and came back out and it wouldnt do nothing. Pulled all the fuses and relays out swapped some of them around and still nothing! Went back today to try crossing the starter over and got it running. Was going to try getting it home and got it a little ways down the road and it wouldnt make it up the hill. I had it mashed all the way to the floor and wanted to die. So turned around and got it down to auto zone and got them to hook it up to their reader. It said I had oxygen sensor bank 1 and 2 and a torque converter clutch sensor. What would cause it not to get power to the starter and when I get it cranked all them codes coming up. I noticed when driving it the O/D light was flashing. Any help would be appreciated Im unemployed and cant afford too take to a dealership and change parts that dont fix it. PLEASE HELP
