Hey guys! I need some help. I have an 04 6.0. My truck was running perfect, no problems. I start my truck, it started idealing rough for a couple seconds then just died. After that it just kept cranking and no start. There are no codes, tried unplugging the ICP sensor and nothing. Checked the fuel filter and its filling up with fuel before cranking. Oil is at a good level. FICM is reading 46.5-47.5 before cranking. Checked the ICP psi and it's at 11 psi before cranking. New HPOP installed in October.

 

What is the ICP pressure while cranking? Do you show cam/crank sync?
