I have an early 03 6.0 Super Duty. 100,1010 Miles. I have had all 8 injectors replaced at one time (5 failed) along with FICM @ 50K??? Recently one new injectors at 98,000 miles due to using Idaho Bio Diesel. And a flush of fuel system and new filters.
Now at home with 100,000+ miles on the truck, it wont start. Turns over fine, just no fire. There is a slight leak in the back of the block near the ICP. Not enough to drip on ground. YET. The ICP has been replaced twice before. I personally clean the EGR Valve every 20K because I once had troubles. I have now been informed that I need to replace the complete engine harness. A job that I thought was the ICP, turns into the whole harness. Does this sound right? And what about the seapage near the ICP?
