06 6.0 no start

[Ranger429]

Posted in the 911 section and am getting little help.

I drove the truck home from the shop this morning and all went fine, about 3 miles. Started the truck about an hour later and it ran for maybe 3-4 minutes then died. Prior to dying it loped a couple of times and then just quit.

I restarted the truck and it ran for maybe 15 seconds then died. I again restarted the truck and it ran for 5 seconds then died. Now it just cranks.

I replaced the ICP sensor, no difference. FICM is at 49.5, reset button for the fuel pump switch in the cab is not popped, all fuses are good and there is plenty of fuel at the top fuel filter.

Anyone have any ideas where to go next short of having it towed to the dealer?

How many miles, how long have you owned it, and what's been done to it? Any recent repairs?

Any logged codes? Do you see the oil pressure gauge moving up when your cranking on it? Do you have any way to monitor ICP pressure? Or at least ICP sensor voltage?

Kinda sounds high pressure oil related but I need some more info.

Bought the truck new, 54K original miles. Oil changed regularly, Motorcraft filters and Rotella 15w40 oil. Last oil change I changed to 5W40 synthetic. Never been in the shop for anything and still retains all factory items on the motor.

Oil pressure gauge in the dash does not move with extended cranking.

Had thought I could check ICP pressure on my scangauge and had a reading of 0, I have since found out that is not the case as scangauge wont read ICP readings.

In the meantime though I made my way over to the Ford dealer and bought a new ICP sensor and installed it, still wont start.

WOW! This sounds familiar!!! I'm still not having much luck figuring mine out...hope you have better.

Funny you mention that, I just read your entire thread. If you keep posting here this thread is sure to get some attention.

Oh...the same old horror story! I have read about this on the forum a gazillion times but I am in need of assistance as well. I changed the fuel filters on my 06 Ford F250 6.0 recently and believed it is "air locked"! There is plenty of fuel in the top filter and I actually got it running for about 5 seconds three different times. Eventually it killed my batteries (needed new ones anyways) so I replaced them and got it to start again for about 3 seconds. When I take the cap off the fuel filter the fuel pump cuts on and fills it with fuel but I have noticed there are still a few air bubbles that pop up from time to time. I have primed and cranked...primed and cranked...any ideas? My truck was running fine until the fuel filters were changed. Thanks for any suggestions!

OMG, shotgun girl is on this thread? I'm going to post the crap out of this thread now!! Jk.

Pull your oil filter. There is a little valve in the bottom drivers side of the filter housing. This is the filter drainback valve. Hold the valve shut and have someone crank the engine. Oil should start filling the filter housing within 3-5 seconds. If oil is filling the housing then it's not a low pressure oil issue, it's a high pressure oil issue.

Sometimes a big enough high pressure oil issue can cause the oil pressure gauge to not move up. Doing this test will narrow down which system has failed. Check that out and report back and I'll tell you what to check next.

So this happened as soon as you changed the fuel filters? Where is the fuel level at in the tank? When you key on with the upper filter cap off does it fill up the bowl rapidly?

I'll try and answer a few questions but might be easier to start your own thread. Just gets confusing when trying to reply to multiple issues....

OK, going to try it now. I'll report back the findings. Thnaks

The fuel level is just above 1/4 tank. When the fuel pump cuts on it fills the reservoir very quickly! And there were NO problems with my truck until the filters were changed.
