Message: [QUOTE="zankof, post: 461429, member: 2980"] 2003 f350 7.3L Stock minus a diablosport economy tune. Okay, so I went on a long road trip this summer across canada, drove 10000 miles in 3 weeks. My truck ran like a top the whole time, never missed a beat. Got home, parked it for a week and drove the wifes car because I was too wiped from vacation to unload the truck so I could drive it to work. Went to start it the next weekend and had issues getting it to start. but it started. fast foreward a couple of weeks. weather turns colder, (38 degrees today), Have trouble starting truck again. Figured might be something with the glowplug system, so I pull out the multimeter, find that i have two glowplugs that are completely dead. GPR was good. Replaced bad glowplugs, put truck back together and it still wouldn't start. Did some research that indicated it might be the ICP. when I unplugged it it started. Ordered a new ICP and went to start it. Would start with it unplugged this time, still won't start with new ICP installed so I guess now i have a spare ICP. No codes show up after cranking. Batteries are good and show 12.3 V and don't drop down below 11.1 when cranking. ICP is showing more then enough presure and jumping over 500 PSI almost immediately. RPMs peak at 580 Truck sounds like it wants to fire but never quite does fires up. Scanner shows that my manifold air temp rises to over 80 degrees C Fuel bowl is full and both my pre pump filter and the underhood fuel filter. Oil is new and up to proper level Getting puffs of dark Black smoke from while cranking. Not sure where to go now, any help would be very appreciated. [/QUOTE]
