Please Help
Ok here is the deal. I have a 2006 ford f350 6.0 for the last month or so it has had a hard time starting and has a lot of white/blue smoke for the first 15 minutes or so of running then runs ok other then it feels like it has a miss. Anyway on Tuesday we shut the truck off and it sat for about 8 hours or so and we could not get it to start then it totally died. Yesterday we replaced the starter and it took forever but we finally got it to start. Drove it to the store and then home and seemed to run fine. TOday it will turn over and tries to start but just won't. We changed the fuel filters and are wondering if maybe they atre the problem. We used micro guard filters could that be the problem or is it something else???

Have you checked your batteries? If they're weak your doing allot of damage to the FICM/injectors on these motors. The smoke could be a couple of things. Not that it's going to make a difference right now, but Microguard filters are not the correct spec for these engines.

The batteries should be fine. We just replaced both batteries in July so I wouldn't think they would go weak that quick. It turns over fine just like its not getting enough fuel to start it. We also replaced the ficm but it was a used one so I don't know.

(jump down to the test for a 4 screw FICM)
If you FICM is bad, I'd talk to Ed at FICMrepair.com before I bought a new/used one. For grins & giggles, if you've got the cord...plug the block heater in for a couple of hours and see if that will help the truck start. It would rule out several things and narrow it down to either glow plugs or FICM.

zhilton. The fuel pump is working I can hear it. We changed the top fuel filter today it was only half full?? Just put the old fuel filter in the bottom and it is sounding more like it wants to start then it did before. It will run for a few seconds the quit again. Also it has been plugged in all night.

The plugged in help take the glow plugs completely out of the equation and limits the FICM's involvement (ruled out cold start issues). Still need to check it for proper voltage (link in the 10th post of this thread). Granted it isn't a cut & dry issue that way...it will at least help tell you if the FICM is suspect or okay.
For the sake of discussion, how much fuel is in the tank? I know it sounds stupid, but you'd be amazed what tunnel vision does to diagnosing problems (don't ask how I know this).

Half full sounds about right if you pulled the little filter out. If the filter was still in...might have something to do with that filter in the HFCM (primary under driver's door) maybe keeping enough fuel from getting to the engine. Still wouldn't hurt to get a fuel pressure gauge on it to figure out if there is enough pressure to feed all the injectors. If your starving 2-3 injectors the truck won't start or won't stay running.
