2000 F-350 7.3 wont start

[papahawk]

Yesterday my F-350 just died & wouldn't restart. The fuel filter housing seams to be getting fuel in it. All filters & oil changed on the 26th of December. Temperature outside isn't a factor. I've replaced cps other times when it would die & restart. I took a chance on that being it again & replaced it but it didn't help. Cant find any broken wires or obvious things unplugged. Any ideas would be greatly appreciated!

Have your batteries checked to see what kind of load they are pulling. Also, are there any codes stored? My dad replaced both batteries on his 99 PSD with Interstate (blems) and his truck would crank, but wouldn't start. Ford dealership found one of the batteries were bad and was pulling too much voltage away from the IDM, thereby not firing off the injectors. Hope this helps.

check # 30 fuse. when the fuel heater shorts,that fuse blows which also controls the idm. mine did it last month. If so unplug the heater and replace fuse.

I had the truck towed into dealer on Monday & they ran some tests. It turned out to be the injector drive module. (very expensive) Thanks for the info though! I'll remember that #30 fuse powers both fuel heater & IDM if I ever run into this situation again.
