You are correct the TPS should be steady with no glitches in it, they tend to burn where the throttle is set the most (ie highway speed) if you have access to a lab scope you can watch it even better and see if it has any spikes in the ramp on the scope. The hardest thing with a Ford and a TPS is they won't set a code till they are completely junk then the truck won't hardly run at all.

On the fuel pressure it sounds ok and if the truck runs OK when it is WOT or under a load without loosing power you should be OK, also the FP should go up when you gap the throttle or any time the FP reg. looses vacuum.

I hope you get it going and let us know how it runs. With the price of gas you can't have any big block running bad or it will run you to the poorhouse with fuel costs quick.
