I have owned several 7.3s from the first year 1989 thru the 2001 I now drive and they have all been great engines. In 2003 Ford started using the 6.0 and that is when the issues started and Ford hasn't found an engine to even come close to standing up in place of the 6.9-7.3 model.
Ryan, I'm sure that whatever the issue is, it's won't take much to get it up and running and you will be very happy once you start using that truck.
I am always watching for more 1999 to 2003 Super Duty's to add to our fleet!!
