--------------------------------------------------------------------------------

This 2005 F-350 (Sept. 2004 build) truck is my daily driver and I need to fix it ASAP! Thanks in advance for any input.

I'll start by explaining my issue and follow with a list of recent repairs that were done in efforts to chase the problem.

I go to start it after sitting for at least a couple hours, it will crank, start and immediately die. I have to press the throttle a little bit and crank it in order to get it to start and idle. It will idle (smoothly) as long as I leave it sit there. I jump in to leave, as soon as I put it in gear (R or D) it dies just like I turned the key off, no sputtering etc. I have to drive it with 2 feet (gas and brake) until I'm moving and for the first 2-3 stop lights. After that it idles fine and runs perfect. It is not lacking power at any time during this process, just simply won't idle when I first start out.

DTC codes:
-EGR flow (due to EGR delete kit)
-Occasional Cam sensor
-Occasional P0611 (FICM)

Recent changes:
-Updated STC fitting
-Replaced IPR valve with a known working unit and a new updated screen/o-rings. (screen was punched on mine causing a no start issue, this problem has been ever since re-assembly.)
-FICM wiring harness
-EGR delete
-Replaced ICP sensor with good known working unit.
-Replaced throttle pedal with good known working unit.
-Replaced FICM with good known working unit.

What next??????

I don't think its a HPO leak since it runs perfect when warm and oil is thin. I can let it come all the way up to temperature in and it still does this.

Furthermore, I will not take the truck to a Stealership and have them charge me $200+ for diagnosis. I will figure this out on my own and the help of you guys!!

I have an AutoEnginuity (AE) scanner I bought and have played with a little but can't figure anything out with it...

Any help is better than nothing!

Fuel pressure ok? When was the last time the fuel filters were changed? Fuel pressure can only be checked by hooking up a gauge or sender unit at the test port on the secondary fuel filter housing, really easy to access and test. Cam sensor code could also be a faulty cam sensor. Need to know what your icp pressures are reading also. Since your ipr screen was punched, could be debri in the hpop system and your hpop is weak.

Harry-
I haven't tested fuel pressure with a gauge but if it were a fueling issue I would expect a stumble, not an immediate shut off. All filters and oil was changed when I did the IPR valve etc. sorry forgot to mention that. Also I changed the Cam (CPS) and Crank (CKS) trying to solve the problem, I thought I included that in my list above but I forgot.

Thanks for the input, I will read the ICP tonight and post my results. I think with a low fuel pressure condition I would feel a stumble like its running out of fuel. If it were a weak hpop it shouldn't build full power ever. If I pull out of the driveway I can go WOT up to 100mph if I wanted but as soon as I let out of it and come almost to a stop it will die, just like I reached over and turned off the key.

I had a 04 that would start and die after sitting. If i parked it hot and started it back up it was fine But if i parked it hot the next morning it would start right up and die. If once i got it started i then shut it down never letting it get hot then the next morning it would start fine and not die. it was tough to figure out But it wound up being the check ball in the HPOP was stuck open but only a slite bit. and it would let hot oil bleed back through but would not let cold oil bleed back through. I replaced the HPOP. Yours sounds Like it has injectors that are bleeding off oil and once they get hot they operate normal. Have you had the valve covers off that is where I would start looking for a HPO leek.

Thanks.

I picked up a set of injector o-rings and plan on replacing those this weekend. I have had the 4 injectors on the driver's side out before so its a good possibility something is leaking, either bad o-ring or one of the hold downs loosened up some.

Well, I'm back to the drawing board! I replaced all the injector o-rings/fire rings this weekend. Also did the updated stand pipes and dummy plugs while I was in there. Still the same issue, stalling upon start up and until the truck is driven a few miles.

I'll take any suggestions at this point, throw them out there even if they sound stupid guys, I need some input here!

Thanks!

Even though he hasn't been on in over 9 years, maybe the OP will get a "wild hair" ............
