According to engine-codes.com the code is for a problem with the glow plug circuit on bank one. That circuit would need to be checked.

Had similar problems occur on various Chrysler products manufactured since 1986. What I did was remove the computer from the car and then take a Dremel tool with wire brush attachment and lightly buff all the pins of the computer--tops, sides and backs. After this I then take a jewelers round file and insert the tip into each connector pin hole and very lightly file it to remove any corrision. When I reassembling the connector plug to the computer I placed a good size dab of silicon grease on the plug in the center (acts as a seal when seated). This has eliminated the problem on four different vehicles.

99 FordF250 Code p1391 & p1393


Hello
Here are the meanings of these codes.
P1391 FORD - Glow Plug Circuit Low Input Bank #1
P1393 FORD - Glow Plug Circuit Low Input Bank #2
I think you most likely have a burnt out Glow pug controller. Whenever this controller is replaced all glow plugs should be tested for proper function.
