Alright now I tried for an hour to figure out how to test the pressure then spent another hour looking for something on here, no cigar. Im used to the old convenient schrader valve on the rail. I searched for one on this baby and I am having no luck. So can somebody clue me in as to how to go about testing the fuel pressure on her? Thanks

And yes sir I did. I put the CPS off the old motor on the new one.

On my 2001, it's on the rail, passenger side, way in the back.

The skeptic in me is wondering if that engine was damaged in a wreck while still in the original vehicle, and not when being shipped to you. What you thought was shipping damage could have been crash damage and the oil in the intake could be from a rollover crash.

If it was damaged in a wreck while running, are there any sensors besides the camshaft sensor that could be causing your problems?

Actually I'm positive that it was damaged during shipping. just the way that the pallet was damaged and everything. I did take the other other sensors an and everything from the from the original motor because I knew that it was all in working order. And on the fuel real there's definitely no port. I even checked the assembly that's not in the truck. So can anyone help me out testing the fuel pressure?

I think they make a test fitting that is installed between the fuel line and the rail. What a pain...

I would say get some new coils for cylinders that misfired. Have you reset computer? What codes SPECIFICALLY were thrown?

Well I got ahold Ford and they knew nothing of any kind of fitting, they said they just used the scan tool. So I built my own fitting and tested just after the fuel filter. It's got 32 PSI at idle and 40 PSI at wide open. Why I was under there I noticed a little oil the outside of clip on the PCV valve, drivers valve cover. I pulled it off at the throttle body and it was slightly damp with oil inside the hose, think this is connected? As far as the COPs are concerned I don't think they are the issue. I don't see how I could lose like 9 of them in the snap of the finger. The codes were all missfire codes. Whats next here?

Rest computer, yes. Cleaned MAF, yes. Cleaned throttle body when engine was dropped in a few days prior. And ran a tank of sea foam through injectors. Thats my best version of cleaning them.

Is this fuel rail, injectors, from your old motor or did they come with the engine, you may want to get this
Ford 6 8L V10 Fuel Injector Service Repair Kit O Rings Seals Filters | eBay
I'll tell you that if this motor sat with any kind fuel in it the varnish build up is just that varnish. When I redid the carbs on our boat that the prior owner did not run very often the old fuel gets so hard that when you clean it out it's almost like plastic chips. How many of the cylinders are reporting misfires
