Bad glow plugs most probably or the glow plug controller. to check your glow plugs remove wire and check with ohm meter to ground. if they are working you should get a low ohm reading if one has a high ohm reading it is bad. if all injectors check good make sure your fuses are ok, also check and see if you hear the controller click when you turn the key to on. Does the wait to start light come on?

The block heater is already installed in your 6.0. The cord may not be there as it is an option in some states and standard equipment in others. The best way to see if your cord is there is to crawl under and look up by the # 4 cyl and you will either see 2 prongs sticking out for the cord or you will see the cord. The cord should end in the front bumper behind where the front tag would be. If you dont have the cord Id suggest getting it off ebay as it should be cheaper than the dealer. Hope this helps.

If the truck has good batteries and cranks well.--- There is a schrader valve on top of the fuel filter housing, (it looks like a tire stem valve) depress this valve while someone cranks the engine until you have fuel flowing out of this air bleeder valve. From that point, crank until it starts. Do not crank more than 30 Seconds, then let the starter motor rest. After you have this air out it usually startes in one or two tries.
When was the fuel filter last replaced? What precedded this no start condition? Was it running fine?
Agin, this truck must crank quickly in order to start

Ok, lets take this from the top. I have a 97 f250 diesel. In mid may mine did the same thing. It's either one of two things. You have under valve cover harnesses (uvc). They slide in under your valve covers, you will see two wiring harnesses on the outside of the valve cover gaskets on either side of the block. Ok, it IS possible one of these slipped out of place and killed two of your injectors, causing the horrible running/ low idle/no power/ sounds like the truck is going to stall symptoms. The easiest way to check that is to unplug the wires while the truck is running and see if it kills the engine, if it doesen't unplug the other one on the same side of the valve cover. If both of these don't cause any change then you have a bigger problem, the IDM (Injector drive module).
FAIR WARNING: When you unplug the wires with the truck on it is extremely dangerous, it is 110 volt feed. It can kill you.
OK, the IDM is a silver box, 8"x10" approx dimensions, located on the driver side under the hood, over top the front tire. If you take the wires you unplugged and take a multi meter to them and they are dead, you have a bad IDM. This was the case with my truck. Ford designed the IDM to have a hole in the side to allow condensation to escape from it, unfortunately, this allows water inside and will short out resistors and practically kill half of your engine. Buy a new IDM on ebay for about $380. It takes 5 minuts to put it in.
I hope this helps you out man.

that fuse powers pcm fuel heater and some other things. when the fuse blows the pcm shuts down. causing it to not run. usually its the heater that is bad. it is located at the back driver side by the fuel pump. you can unplug it and see if it starts. if so you will need to replace the heater
