Hello , I have a 06 F350 6.0 . 184000 Miles, use Roettla oil . I've owned it for about 1 month , during that time it ran great . Then I had trouble starting it . There's no codes , no check engine light , no oil leaks or coolant leaks . The icp-dsd reads 780 psi while cranking , FICM reads 48v . All other repairs were done by Hallas Performance . Performed wiggle test on wiring and connectors. The FICM is missing the rubber insulators . It will start cold all day as long as you turn it off quickly , but if you drive it , it won't start if it's driven about a mile . When it cools off it will start .
