Ford 7.3 hard to start

I am working on a friends 02 F350 with a 7.3 engine.It acts like the glow plugs are not coming on.All I have is this P.O.S. Haynes manual.It has no schematic.No info on testing the glow plug relay or the sensors for oil temp or coolant temp.The thing is useless.Any body out there got a Chilton Shop Manual for the 7.3 in a 2002 F350?I need to know how to test if the glow plug solenoid is good or what the resistance on the thermistors for oil temp and coolant temp should be since they control how long the glow plugs stay on.I changed the fuel filter and that cured the stall at idle.It shows no code so I suspect the glow plug solenoid.I live in cold country and the block warmer for this truck can't always get plugged in.I did not find anything on this when I searched this thread.I have no diesel engines of my own so I need all the help I can get
