6.0 Motor problems
Hi, I have a question about my truck(03 F350). No start issue.
when I disconnect the FICM, the high pressure can go to 800 or 1000 PSI when cracking.
but when I plug FICM in, now matter how I crank, I can only get ~400psi. hence now start.
The FICM voltage is good at 48.5 and FICM sync is 1...
