truck died
Was heading home driving my 03 f550 about 250 miles from my house, driving along truck just wouldn't excelerate pulled over truck it died.
towed it to the dealer, next day they called said icp has low voltage they are ordering a new one and installing it tomorrow, they also said it could be hpop
does this sound right. I don't have much experience with 6.0 motors

I would be leary of the explanation they gave you as you should be able to unplug the ICP sensor and still start the truck. Although ICP sensors on 03's are very troublesome they usually cause a surge when they fail. I'd be more likely to believe the HPOP (or a high pressure oil leak) than ICP causing your truck to die.
This is from the troubleshooting a no start condition in the tech folder at the beginning of the 6.0 forum:
TROUBLESHOOT THE HPO PRESSURE SYSTEM:

Determinimg if the ICP sensor is seeing 500 psig minimum (see post #23 in link below):

If possible, you can pull the ICP and install a pressure gauge to check the pressure in the “high pressure oil system”. Crank the engine and watch the pressure. You need 500 psig to start. The fitting needed for this is the same as that for the fuel pressure test port.
Here is a way of checking to see if you have sufficient high pressure oil without having a gauge or adapter. Strip back the wires about an inch away from the icp sensor connector. Obtain a digital multimeter and set it for voltage (DC). The bn-wh wire is a five volt reference, leave that alone. Strip back the db-lg signal wire and the gy-rd ground wire. Put positive lead on a dark blue-light green wire and negative lead on gray-red wire. Have an assistant crank truck, you need a minimum of 0.80 volts (500 psi) for the truck to start, if you are getting greater than that then you have sufficient high pressure oil.
To check your ipr and hp oil system:
1. Get an ipr connector from Ford and put 2 long wires on the end, plug it into the ipr. Later you will attach the 2 long leads to b+ and negative ...... this will close the ipr.
2. Then remove your icp sensor (04.25 and up truck??) from the passenger side valve cover and thread a fitting in with an air fitting on the end (so you can apply compressed air to the hp oil system).
3. Remove your oil fill cap, your intake up to the turbo (get the ccv out of the valve cover at least), and the hot side cac tube.
4. Then, command the IPR closed for only 30 seconds, apply 100psi air to the hp oil system and listed to where the leak is coming from.
When you hear it you've found your problem....that is assuming you have a hp oil problem.
If your building low and high oil pressure fine, then you've just wasted your time.
Generally on no-start conditions that are related to "high pressure oil" leaks, the vehicle will still develop low pressure system pressures. However, the plug on the H.P. oil feed can occasionally blow out, the H.P. pump seal can blow out, and on the '03-04 trucks the ball on the side of the H.P. pump blow out - causing loss of base oil pressure.
Hard start - no start conditions related to the HPOP could be attributed to the following components in the high poressure oil system (air test while hot will determine the root cause):
h t t p://www.*******.com/forum/showthread.php?t=11583
(leave the spaces out of http and where the asterisks are insert the word "ford truck fanatics" with no spaces)
Faulty IPR valve
Leaking snap-to-connect (STC) fitting (05 and up model years)
Leaky or cracked branch tube
Leak with the stand pipe
Leaky or cracked oil rail (including oil rail end caps/plugs)
Leak in the d-rings of the oil rail front port plugs (or dummy plugs)
Leaky o-ring on an injector; or leak at the top of the injector where the ball tube from the high pressure oil rail connects to the injector.
Weak or failed HPOP itself
Low base oil pressure (failed oil pressure regulator).
Low base oil pressure (bad low pressure oil pump - LPOP).

so I got truck towed home from dealer, they did the diag said the hpop needs replacing .
so Im going to replace hpop, oil cooler, turbo drain update , and install sinister egr delete ,is there any other updates for 2003 6.0 that can be done while Im in there.
Thanks ahead of time for any info
