I have an 04 f250 6.0, build date is October 1st 2003. Recent work done to the truck: new engine wiring harness, new fuel injector wiring harness, 4 new injectors driver side, new oil cooler, new IPR, new FICM half shell, new ICP, coolant filter upgrade, Blue Spring fuel upgrade. I am having a no start issue. Conditions: HPOP 600 + psi on cranking, duty cycle 25 to 30%. I have replaced the FICM relay and check the logic power fuse both are good. I am getting codes u0105 and u0306. Upon key on sometimes i get injector chatter and it will crank but soon dies then no chatter and no crank. Please help!#!!!!!!!
