6.0 wont start
#21
Answer the questions posted already, otherwise we really can't help you.
The 6.0 has a crankshaft and camshaft position sensor and both will typically be thrown as codes falsely when someone is cranking the truck an awful lot trying to get it started. It is possible it could be that, but unless that code popped up a while ago before it wouldn't start, I wouldn't count on it fixing anything.
Unfortunately I feel I have nothing else to offer in the way of help without knowing more...

i did some research, IH borrowed this concept on how this works from CAT (just like the injection system)
If the crank sensor fails, a code will be logged, but the truck will still start and use the Cam Position Sensor as its reference for engine position and timing.
If the cam sensor fails, a code will be logged, but the engine will still start and use the crank sensor as its reference for engine position, but will change the timing to FIXED and adjust it 2 degrees per revolution until the correct timing is reached. (will start but takes alot of cranking)
unlike the 7.3's when you loose the cam sensor...... its all over

When it was cranking the ficm was putting out fluctuating between 46-48 while cranking and was smoking. it wasn't the crankshaft sensor it was the cam sensor that was bad putting it on in the morning if thats not it. it has to be the ficm. I really do appreciate the advice i can only check this thing in the afternoon during the week as i work during the day. my next question would be how reliable is having the ficm repaired vs buying new?

A new FICM will still have a minute amount of solder on the boards and eventually the same problems.
If you have smoke coming out while you're cranking it, I don't believe it to be a FICM. Especially if you're getting 46-48V. Though, that doesn't always mean they're good.
If you're getting smoke while cranking though, that tells me you're getting fuel, just not getting a full burn for some reason.
Have you done any maintenance recently, or has any work been done at all? Did the truck just develop these issues out of no where, or was it a gradual thing?

It was beginning to take a little more time to crank it. But the truck ran fine that day parked it for the night got up the next morning to go to work and it was turning over (with smoke) but thats all it would do then I drained the water seperator, pulled the fuel filters, and drained some fuel from the lines by disconnecting the line from the block and cranking a few times, replaced the filters and primed, still wouldn't start. I also pulled and cleaned the egr valve.

What does it usually run to rebuild a ficm?

Ford charges $900 for a new one without programming
They also offer a "half shell" for around $400
Swamps charges like $450 and a $300 core I believe, or something silly.
Like I said, I seriously doubt it's your FICM.
In the beginning you said check engine light was on... did you ever get the codes read? That will help us tremendously....
