FICM, Harness, or something else.
I have a 2004 Ford 6.0L that died while driving a couple days ago. The
engine all of a sudden quit and when I tried cranking it felt like it
was hydrolocked. I let it set for awhile and tried cranking again and
it would start up but with excessive white smoke and oil leaking out
of the turbo into the exhaust. So i did some looking around and it
lead me to the FICM. I have a four pin ficm and I get no voltage at
anytime when I tested the post on top. After taking the ficm off the
motor and looking around for a chafe in the wiring harness (didn't
find anything) I reattached the ficm and now it doesnt start at all. I
discovered that there was a 50A fuse which I checked and sure enough
it was blown (Still no voltage.) So after replacing the fuse when I
turn the key forward or try to start it blows the fuse. I took the
first harness off toward the front of the ficm (front of the truck)
and it doesn't blow a fuse anymore. If it was the wiring harness
wouldn't the fuse blow even if the ficm WASN't plugged in?
Do you think the FICM is fried?
