#1 check the cigarette lighter fuse, pcm uses same circuit.
#2 the 7.3 diesels from 1994 threw 2002 pcm"s need to be manually identified. do not use auto vin, simply turn off auto vin in your settings.
#3 double check that the fuel bowel heater fuse is there. not uncommon to find it gone. people will remove it when the heater shorts out.
