Starting issues
Hello all, I have an early 04 build date Sept 11 03 with 70k miles, on occasion there is a starting issue, always after the engine is warm never when cold. It's difficult to explain it seems to hit on all cylinders but is very week like starving for fuel then it picks up and runs fine cranking time is a few second longer during this condition I have just serviced the truck new air filter, fuel filters oil change RP 15w40 and oil filter all motor craft. in hopes of a fix no joy when changing oil I did notice a small oil leak on the drivers side on the aft of the engine. could this issue be high pressure oil pump related?
Also about 6K mile ago I pulled the egr valve to have a look it was clean and looked good. BTW this was a California truck it lives in Alabama now.

You have done the basic things. It could be the ICP sensor. That is common on the 03's and 04's to "act up" look for an oil soaked connector.
Here is a "no start" thread that may help:

Thanks guys. I did load test the batteries they were the same at 11. ? I can't recall I am presently offshore so I won't be back to the truck for a couple week. The ICP sensor does make sense. The truck does run great otherwise. I also have a Banks monster exhaust. I also notice some light black smoke when I gun the engine is this normal? My old IDI did but this 6.0 is a totally different beast.

ICP sensor on this truck is in the right front valve cover and not normally known for failure (late model 04 engine). Sounds to me more like an injector issue. My truck is doing the same thing. I describe it starting like an old Johnny 2 popper. Fires off slowly and starts to pick up speed??? It may or may not show a code, but IDS can detect a weak injector IF that's the issue.

I was under the impression that all 03 and early 04 trucks had the ICP back under the turbo and not on the right valve cover.

I thought the same, I know I read that the ICP was moved betw. early 04, which I guess would be late 03 engine build which is what mine is, and late 04 build, which would be an early 04 build date. Is this true? I haven't looked for the ICP on my truck, haven't had a need to really.

According to some of my (hard to find) references, the 2004 model production begining 9/29/03, placed the ICP on the passenger side valve cover. 2004 MY production BEFORE 9/29/03 did have the sensor under the turbo.
I have had it in my head that the move was in early '04 rather than Sept 2003. Hope I haven't misled folks - I have always posted that later 04 models had it moved and the early model years didn't. I guess it was the EXTREMELY early model years only
Nice catch npccpartsman.

Bismic thanks for the spread sheet I got some months ago I may have forgotten to thank you I can't remember. I do appreciate everyone's help. The truck does start it just doesn't start crisp as I think it should at times. Is it possible that the fuel pressure regulator is at fault? I did get an oasis report on the truck some months ago I can't seem to find the engine build date on that report the truck build date is Sept 11 2003 I have been a member since 2007 and yes I can be accused of lurking I don't know a lot about these 6.0's my daddy always said if don't know something keep you mouth shut and ears open. Anyway if I can provide more info please let me know.

The "never when cold" statement sure points to the HPO system, but they can be hard to diagnose without the proper tools. I have not heard of the fuel pump or the fuel pressure regulator having problems hot, but not cold. I guess it could happen, but I have not read anything talking about it. May be time to bite the bullet and see what Ford diagnostics can tell you.

Bismic I think you are right I shall do so. I guess while I am at it I may as well get that occasionally dripping egr cooler hose attended to and flush the cooling system I found a site that sells "heavy duty EGR Coolers" anybody have thoughts on that.
