This should be the part number for the complete filter housing harness
Fuel Filter Housing wiring
(Ford) F7TZ-9S277-AA
(International) 1807333C91 ???
(International) 1825754C91 (Not Available per IH)
Link to buy it
Powerstrokeshop.com
Check the IPR connector for one of the wires to have 12 volts on it like Action4478 recommended. that won't tell you if the other wire is any good but an ohm meter would it you unplug the other connector and check for continuity between the two.

Thanks again TJ ........ Would you happen to have a diagram, scematic or drawing of exactly which wiring or pin connector goes to what sensor or the IPR connector ...... Im asking just to make sure I didnt wire it wrong when I found the fused, burned wires ....... I do have a spare injector connector that I could use to replace my possibly damaged IPR conector.

Well another 5 hours working on this truck and still NUTTIN ...... I pulled out the fuel bowl again and totally checked out the fuel bowl harness ..... I used the connector from an old injector connector and changed the wires to the IPR also ..... I tested the wiring with key on and gotting voltage on one side connector and ground on the other side and so that elimanates that .... Disconnected sensor to put into default ...... Ive switched from one IDM to another to check that with both IDM's supposedly working and nothing..... 45 psi on fuel test port ....... Both batteries fully charged and cranking strong and even plugged in the block heater overnight and still no start.... all fuses checked ..... CPS changed ..... WHAT ELSE IS LEFT??

Any smoke out the tail pipe when cranking? Also have your check oil level in the HPOP reservior on the front/top of the motor? make sure it is full. it may be empty from all the cranking you have had to do.

OK fuel pressure is down again ...reading 10 PSI only now ......... earlier I was getting 45PSI ..... now down to 10 PSI ..... my fuel pump is only about 2 years old what else could cause the fuel pressure drop??

New fuel pump installed and fuel pressure back up to 50 psi ..... Still no start... Ive purchased a 5000psi pressure guage and mounted it on the oil rail on one cylinder head and then the other ..... Im getting very little pressure during cranking .... like maybe 200 to 300 psi .... Ive checked the IPR valve harness connector and It has voltage with key on position ..... Ive connected my old IPR valve that I took out of the truck earlier to the harness and key on I get the valve pull in or magnetized ...... Ive isolated each cylinder by blocking off the oil line to the other head and disconnecting the power harness as described in this site and still no pressure on either head ....... through the process of elimanation that leaves only the HPOP left and so Ive ordered one ...... The only other possibility is the ECM and maybe I need to replace that also.

IPR 12v one wire ,,& PCM sends ground to the other ,,,
Have you checked the small relays in the power distribution box ,,,You said the WTS light is working ,,Is the CEL on at the same time ?....

New IPR identical to old one ........ besides I removed the new IPR and retried the old one which was working at the time I changed it .... Still no start ..... Ive checked all relays and fuses # 9 and #22 especially and switched around the relays to be sure ... HPOP harness checked for power with key on and getting power WTS light working ... Im open to new suggestions.

Lets look at this simply, your truck ran before you replaced the ipr, so you either have something ipr related or regulator related since yuo had that apart too.
did you double check the ipr o-rings? make sure they didnt get cut.
how long of crank time are you giving it? sometimes it takes a bit of cranking to build the pressures back up for the first time.
if you are building pressure then i doubt you got the wires backwards on the ipr.....
when you put the fuel regulator back on is the larger o-ring sealed properly? could cause problems if you are suckin air.
you said you lost/broke some peices of the regulator and had to replace them, make sure you have fuel pressure at the heads themselves. if nothing else crack the line at the head.
the only other thing popping into my head falls back to crank times. you said you are only building 300 psi oil pressure yet you are not throwing a 12** codes for low icp and icp uncontrollable. perhaps a longer cranktime to either set a code or build the pressure up.

Im definately getting fuel pressure at the schrader valve above 50psi ..... but very little oil pressure and ive cranked her until the batteries went dead and I mean looong crank times like up to a minute sometimes ...... I strongly feel the problem lies somewhere between the HPOP and the signal being sent from the ECM to the IPR valve .... I spoke to a ford tech yesterday and based on my info he suspects that the signal from the ecm at cranking is not the proper cycle rate for the IPR.

Hi guys .... well so for Ive made some headway .... the truck finally started after changing the HPOP, the fuel bowl harness and the ECM .... Im sure I didnt need to change all but at least everythings new .... But the problem now is the truck only runs until it warms up then shuts off,when I took it out for the first time I got about half a mile and then the CEL came on and the truck lost power, it didnt cut off righ away, seemed like it just went to idle and barely reved a little when I pushed the throttle to the floor, then it quit shortly after ... Refused to start after that ...... I charged batteries overnight and next morning it fired up with one long crank ........ I reved it for a while and then after warm up she quit again ....... One thing ive noticed is that the rpm while cranking is very low like it just jumps a little maybe up to 100 rpm and back to zero ..... but she still starts ...... when the engine is warm I get no RPM reading while cranking and ive changed out 2 CPS sensors ... What do you guys think is wrong now??
By the way I really appreciate the help from all of you.
