Need help with an odd low power issue
I need some help diagnosing a problem with my truck. It's a 2003 F350 SD CC 6.0. It started with a problem last Thursday where it ran normal up to about 35 MPH but when I tried to go faster (with normal push of the pedal) the truck would lose power (actually the normal pinging sound given out by these engines would go away!!) and not go any faster unless I backed off just enough to hear the normal engine sound. Then it would creep up to normal highway driving speed 60-7- MPH. It has normal power below 35 MPH. It did this for a few days and then on Sunday morning I went somewhere and it wouldn’t start. Waited 15 minutes and then it started and I limped home. Any idea of the problem? Stiction? Bad injector?
3000 miles into oil change
7000 miles into fuel filter change
Blue spring
FICM solid at 48-48.5
Batteries only 2 months old
Diesel Kleen
Outside temps in the 40-50 F range (i.e. not cold)
Thanks all for any help.

Did you check for codes? p2285 is the ICP sensor fail code and will cause your issue(s). The ICP will degrade but not pop a code until it actually gives up the ghost. My last ICP was bad for 2 years before it finally went tango uniform.
Pull the plug on the ICP and see if it is oily. It is a b**ch to get to but would give you the answer right away. New ICP sensoris about $165.
I'm on my third ICP sensor in 116,000 miles.

Sorry for not responding guys. I put up this thread then went to work and got swamped. I'll be taking readings hopefully tonight. I have an Edge CTS and just borrowed a Cornwell scanner for live data. There are no visible codes. Truck is all original with 205K on it.

Update with readings
Well I finally was able to work on my truck and here is what I came up with so far; just working on it the last couple of days.
I went out and bought a Scan Gauge II and got it set up to read the items below. For what it’s worth the truck was manufactured 14 April 2003 and the VIN is 1FTSW31P23ED02160. New batteries in January, oil changed 3000 miles ago and fuel filters 7000 miles ago but I just changed them again this weekend. And the initial problem I am having is that all is fine until I get above 30 MPH at which time I lose power and the normal pinging sound of the engine goes away.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com
fficeffice" /><o
></o>
After I took the initial reading at idle, 640 RPM, I upped the idle to 1500 RPM and got pretty much the same readings. Anyway, about 2 hours after completing this I went back outside and noticed a large fuel wet spot on the ground at the rear of the tank. Got underneath and noticed that the fuel was coming from the top of the tank at the rear. Any thought on this? Also, there are no codes or CEL.<o></o>
Here are the results. <o></o>
ICP 715-835<o></o>
EBP would not give a reading for some reason<o></o>
MAT 40<o></o>
FICM Main 48.5<o></o>
FICM Logic 13.5<o></o>
FICM Sync 1<o></o>
IPR 33 +-<o></o>
V ref 4.97<o></o>
VGT 47<o></o>
MAP 14+<o></o>
GPH 0.73<o></o>
Could it be the fuel pump? Is that in the tank?
Any help is appreciated.
Thanks
Paul

Thanks Mustang 309. I had a feeling the FP was there but not sure. I will check the numbers again after temp is in normal operating zone. Why would the tank leak like that for no reason? Is there a possibility something is pressurizing back to the tank? It just doesn't make sense.
Thanks again.
Paul

Yup high ipr, icp above whats expected at idle as well. Icp should be about 520 to 580 and ipr should be under 24%.
That points towards a high pressure pump.
Check icp, icp connector and fuel pressure as well for possible sorces of concerns too.

I just went out and let the truck warm up. Still shows 850-900+ at idle for ICP and 33 for IPR.
Took it for a ride around the block (that's as far as I can go since it is difficult to go much over 20-25MPH) and noticed that under load and approaching 2000RPM that the ICP drops to the very low 500 range and hit 499 at one point but climbs back up as soon as I let up on the pedal. IPR rose to mid 80s for same condition.
I noticed a line of fuel drops follow me into the driveway and then a puddle formed on ground under the tank as soon as I got out of the truck.
Any further thoughts?

Thanks for all the help guys. I'm good at replacing things, working on gas engines/hot rods and stuff but doing these tests and diagnoses is getting over my head. I am really not familiar with all the parts on these engines and where to hook things up for tests. If I knew for sure that is was the HPOP or fuel pump I'd dive in and replace them. But I'm just not knowledgeable enough to tackle the testing. I've gotta think about this a little more and decide what to do next. Might have to break down and tow it to a mechanic.
