IPR (injector pressure regulator) is on the back side of the hpop. Easier to remove if you take the fuel bowl out. You can buy an oring kit from ford or IH, comes with a couple orings, tin nut, etc. I'd try that first. I'll see if I can find the pic.

when you say hard start what do you mean? just a lot of cranking? is it a slower cranking? my starter did this to me once and it kinda sounds like what your talking about. it didnt seem slow to me because of the fact it got worse over a long period of time. im not talking about a dead battery type of crank but just a little slower than normal. seeing as how you said it runs fine after its started i woundn't think its anything else. i would start and stop it with no problem and then out of the blue it was a no go. wait for the motor to cool down and it would start again.

^^^ What 427 Fordman said^^^^ After pulling my IPR out - for a different symptom - I did notice that the oring was "worn/Damaged" and A LOT of threads I read here say...with your symptoms replace the IPR O-ring first cause the oil will thin and find it's way around the o-ring. Yes, it's a given if you want to remove the IPR quickly, then remove the fuel bowl assembly. You can inspect the "Valley of Death" and clean out the area of any lost pocket change... and other items...

The idm sends voltage to the injectors, I'm not the elec. wizard but I think that's right. It's on the drivers side fender, 6x8? rectangular box with a elec plug on the front. I'd try the IPR first, then if no success, take the idm off and shake it to see if there is any water in it. If you know of anyone with a 7.3 from a super duty or another obs try their idm if they will let you. Superduty ones just have a little more voltage but work (actually better than ours).
Seems more of an ipr issue to me.

UPDATE I rebuilt the IPR this morning,gaskets were shot.There was only half the grafite one left and the little oring was in two pieces.The large one was OK.Changed them all,used everything in the kit.Disasembled the fuel bowl,cleaned it entirely,man was that thing filthy.Put a new fuel filter in it and reasembled everthing.Started right up,took it for a 20 mile crank.Got home turned it off,restarted it and wa la,cranked over in a flash.The truck runs perfect.Even idles smooth now,used to shake a bit before.Throttle response is much better also but that could be from a new fuel filter and clean bowl.Going to work all day tomorrow so that will be the real test.Will update tomorrow.
