Help please, Excursion 6.0 just died
I hope someone can give me some pointers. I have an early 2003 (actually late 2002 build) 6.0, which has been fairly trouble free. It has 71,000 miles on it. About 3000 miles ago I changed the oil (royal purple synthetic), both fuel filters (purchased from ford), and cleaned the egr valve, which though it had never been cleaned before looked pretty good! Tonight, after about 60 miles on the road, (mostly freeway, and it seemed to be running good), I suddenly lost power as I came in to town and slowed down to about 40 to 45 miles per hour. It felt like it lost at least 50% power, no matter how much gas I gave it. After about half or three quarters of a mile (while I repeatedly muttered "oh sh**, oh sh**"
), as I had to slow down for traffic, it just died! Now it won't start. It turns over, and the battery and check gage light are on, but it doesn't even sound close to starting. In case it matters, my gas milage seems to have been down a couple of miles per gallon since the above service about 3000 miles ago. Also, I don't have a "code reader", but guess it's time to buy one. Which one should I get? Thanks for any suggestions, I really appreciate it.

First things first. Pull the secondary fuel filter lid and see if you are getting fuel there. If it's full then you need to get a code reader and check it for codes. There are too many things it could be without some more "help" from you. It could be a high pressure oil leak internally, but this maybe sounds like fuel pump died??? All I can do is guess at this point. Just make SURE you are in a safe location out of traffic.

My guess is the ICP
Mine did the same thing except I replaced my ICP before the motor died. First indication was after starting the motor would "hunt",i.e., RPM would go up and down slightly until warm. Then I started loosing power. Like NPCCPARTSMAN says a code reader will tell the story. But if you want to do a precode reader check, reach up from under the truck and grab the ICP connector. If you come back with an oily hand, probably the ICP.

Here are some pics that may help:

The Tech folder has two great threads on replacing the ICP sensor and wiring harness if your truck starts after you have disconected the sensor.

Thanks for the help, and thanks to Bismic for the link, I think I need it. I have checked, and there is fuel under the secondary fuel filter lid, I drained the water trap just in case, but all I got was an arm full of diesel, and I am connecting with someone near me tonight at 6:00 pm (pacific) to borrow a code reader (they have the same engine that I do). I will jump back on here as soon as I have some numbers. By the way, I heard nothing unusual, I.E. idle variations, etc. prior to this, and it seemed to be running well. I will use the pictures that bismic linked to see if I can touch the ICP. So far, with pictures from the 6.0 bible in hand, and a flashlight, all I have been able to achieve so far is a scratched up, slightly bleeding, arm that smells like diesel.
I can't even seem to touch it. Again, thanks!

I have not given up on finding wire chafing, but I have not been able to find any yet. Though it is rare for these to go out, they do sometimes from what I have heard locally, and I am also not convinced that this is not what happened (this would by fairly typical for my normal run of luck
). Having said that, I can't even see the connector or sensor from the bottom or top of the engine, but can tell that it is on the side of the block, behind the air conditioning compressor, not on the front as one of the pictures linked above seems to show. The only reference that I can find, aside from what bismic linked to above, is here https://www.ford-trucks.com/forums/8...on-sensor.html , and this both sounds and looks to me to be like something akin to a doctor pulling your tonsils out thru your belly button 
. matty169, or anyone else, what is the procedure used by professional mechanics to get to this sensor? Is there anything easier than removing 'stuff' off the passenger side of the engine until you can get to it? Thanks for all of your help.

Not sure what picture (link) you are refering to that showed the CKP in the wrong place, but here is a diagram of it:

Just for folks that find this thread in the future.
Now - did you find any chaffing on the wiring harness?
Also, did you ever lose RPM readings?

Sorry bismic, my bad. On the first link of your most recent post I was reading the '2', which is labeled as 'engine block face' as meaning the face which is actually the passenger side of the block, as I now understand. So ... crud ... this will be fun to remove. Thanks for all of your help, I really appreciate it.

It doesn't necessarily mean you need a new sensor, it means that the PCM isn't getting a signal or it's a corrupt signal or the wire is bad. Like Matt said, these sensors very rarely go bad, it's usually a wire or the connector is contaminated with oil. We did have a CMPS go bad last week, which is only the 3rd one I've ever heard of actually failing, but they are very rare. You can spend the time diagnosing, or you can change the sensor (not sure of the cost--probably 40-70) but if you have the same problem then it's most likely a wire anyway, and yes it is in a bitch of a location.
