03/04 HPOP's are all the same and once they are running they usually put out enough oil to overcome a leak. The weird thing is cycling the key/fuel pump and it restarts, but basically no throttle response.
Muskyman--is it possible to get it scanned for codes? I don't expect any, but it might show something.

You do not need to remove the turbo, but it is hard to reach - no doubt!
I wonder if it might not be an injector that is slowly leaking combustion gas back into the fuel filter. You can test this:
Pull the fuse cover under steering wheel with a flat blade screw driver turn the screws 1/4 of a turn. Pull fuses 20 FICM, 40 Fuel pump, and 103 PCM. You might need a fuse puller or needle nose pliers. Be sure there is fuel above the standpipe. If you want pull fuse 40 last and use the fuel pump momentarily to fill the fuel filter housing. Then have someone crank while you watch for bubbles. Do not crank on it for more than 10 seconds max. This is the easiest way to determine mechanical condition of injectors. What happens is combustion gas will come through the pintle seat and into the fuel gallery in the head and up into the filter .

Sorry my plans were changed on me last night and i was unable to work on her,going at her tonight. While trying to get at my icp (holy tight spot) I found a half cooked chipmunk right under my turbo i hope it didnt chew anything or get partially sucked in somewhere.I am going to investigate that aswell. Question though my icp i can wiggle it around i cant pull it up or down just wiggle it side to side.Is this proper or should it be tight in its spot? Cant wait to get at her after work i miss my baby and this taurus makes me feel like a sardine.

The ICP sensor itself shouldn't wiggle at all. It has to hold quite a bit of pressure. Sure you're not wiggling the wiring itself? Sorry, had to ask as it is a PITA to get to. A lot of tech's do it from underneath where the FICM isn't really in the way. Also, check the wiring harnes for oil soaking, which means the sensor and harness pigtail might need to be replaced.
Dang Chipmunks!!! They can cause all sorts of havoc with wiring also. Why they like plastic and metal I'll never figure out. I bet that smelled really nice.

One more thing I haven't asked: Production date of your truck 09/03 or before and there will be ICP and IPR under the turbo. 10/03 and later the IPR will be on the passenger side front of the valve cover and ICP will still be under the turbo. Good info on 03/early04 models here: https://www.ford-trucks.com/forums/8...ml#post7693493

I almost forgot.......Pulling the IPR wire will cause an immediate shutdown, where as pulling the ICP wire will cause a default and the truck will still run. Be sure to tell your mechanic what you have done when he scans it for codes so he can eliminate "false" codes.

LOL--sounds like a good plan on Friday. Does your plan include Musky fishing too?

Muskyman, does it starting "knocking" real loud and then stall? If so then it is probably fuel, a good way to tell is once it has stalled without cycling the key, remove the secondary fuel filter housing and see if there is fuel in there. If not, 60 psi is actually excessive fuel pressure per Ford. The spec range is 45-55, I would check for a restriction in the return fuel lines (unlikely) and then replace the regulator, although that shouldn't really cause a stall. Unfortunately the Ford manuals do not list a flow rate for the fuel pump.
