looks like you've Thrown
every part you could think of at this...
Not a good plan...
So, first, whoever said to you "That's the way these trucks are
" you should stop talking to. You have something wrong, that's Not the way We start at all!
Next, we need to know what your sensors are telling the PCM and, to do that, you need to have the appropriate tool such as, at least a simple app to run on your phone. You can then monitor your HiPres Oil system (which would be my first suspect) As you're trying to start
. What those all important ICP/IPR sensors are reporting.
If you're gonna keep & maintain the truck yourself I strongly suggest you get access to the special scanner software you need to do it.
Here you have a couple of the most common choices;
1) If you want to do Everything you'll ever need to, then look at the AutoEnginuity + the Ford Enhanced Package (@ $350 - you add an old computer of some sort to run it with)
2) To retrieve most of the codes you'll need to help and even do some
testing look at the FORscan Lite or TorqueApp (you add an Android device and Blue Tooth Adapter for @ $30) OR the Windoze version with a USB adapter. I like this one for BT Android -> http://www.amazon.com/BAFX-Products-...dp/B005NLQAHS/
Just a few years ago you needed to buy a professional scan tool because our trucks need to have a scanner with a Library containing both the Ford Proprietary AND the Diesel Specific codes in it. Add to that, our trucks are Not, specifically, OBD-II so the Generic scanners the Auto Parts Stores have are of little use to us. But today there are some very good App based tools, that are close to what the pro tools do, for fraction of the cost.
