Right where it runs against the valve cover by the plug. Why do you suspect harness?

Sent from my phone that somebody didn't help me get.

The codes coming up seem to be heading me that way. Coming up with a
P2617 and P2614. This problem occured last week for a bit, engine runs rough and dies. Towed let sit over night and statred perfect next day, ran for couple hours same thing, luckily just pulling down my street.And here it sits.Kinda missfires when starting and blows out unused fuel then dies. Checked all the norms EGR for traces of coolant, even replaced crank sensor with spare I had. Same codes.

Those can show up from irratic idle and excessive cranking. Are you able to read icp? What year is your truck?

Its a 2003 250 will try right now to see if it will run long enough to get it. You thinking ICP sensor?

Just at a glance those readings are ok, the 03 was bad for icp/pigtail failure. Make sure its not soaked with oil and look over the pigtail. Make sure your ficm plugs are seated well. Can you watch ficm readings and ipr if you get it to run right? Motorcraft filters and caps?

hmmm, those DTCs can be caused by excessive cranking. I'd tend to ignore them unless I found the issue caused by a loss of FICM sync.

I wonder if you're getting combustion gas in the fuel rail

Good point on the combustion gasses. I knew someone would chime in. Op, pull ficm relay, hfcm fuse, and fuel filter cap. Crank the truck over and look for bubbles in the fuel filter housing.

That is the reading when it runs can't really run too good. And the filters are from ford, already learned my lesson on after market filters with my old 7.3. I will try what Southend suggests. Will this cause a skunky fuel smell in thefilter housing? Have that now ,all new fuel and additive added in last tank too.
