my friend has a 2001 7.3 with edge attitude with juice. for a while now it has been periodically not starting with the edge plugged in. we unplug it and wait a couple hours and then it starts up fine and he wont have the problem anymore until about a month afterthe edge is plugged back in. when you turn the key the fuel pump doesnt come on and that seems to be why it wont start. any suggestions on why its doing this or if it even has anything to do with the edge.

 

Sounds like the juice needs to be repaired.
