3 years ago i bought a 2000 f350 7.3 crew cab, long bed, dually. I pulled everything off the truck. This included cab, bed, engine, fuel lines tank etc. Sanded and coated the frame and put on a 2008 cab in the process. I put on new oil pan, valve covers, uvch harnesses, turbo, deleted pedestal, new up pipes, starter and alternator, fuel pump, sending unit, fuel lines and brake lines. New Master cylinder as well. Took some time wiring the cab to the 2000 but got it all working and fired it up. Truck had an extended crank of 8 to 10 seconds which became the root cause of me diving further in. I had oil in the icp harness so I replaced the pigtail and sensor with oem ford parts new. I replaced the ipr and pigtail as well with a new oem ford one. I also replaced the cps with a new oem ford black with pigtail as well. I started the truck and it was running well. I was going to take it for a drive when I noticed it sounded like it was missing a little. I pulled it back into the garage and a minute or so later when I was in the driveway talking to my wife the truck shut down abruptly. No smoke, no noise, no anything. I cranked and cranked and it would not restart. I deadheaded the hpop and didn't get a reading so I replaced the used hpop. While I was waiting on the new hpop I looked into fuel bowl and it was dark enough to concern me that oil was getting into the system so i pulled the injectors and shimmed them all as well with new injector orings. When removing the old orings i found 2 on the back side toward injector were splitting but not all the way through yet. Installed new hpop and still would not start. I again pulled the hpop and this time pulled the resevoir as well. I replaced with an oem reman hpop from an international dealer. Made sure the gear properly seated and aligned with the resevoir off. I torqued all bolts to spec including the 95ft lbs for the hpop gear bolt. I also replaced the hpop lines as well. Truck still will not start. Im getting no reading with the icp connected and the ipr duty cycle isn't moving either. Ive swapped ipr and icp with other brand new units just to verify and still nothing. The resevoir is filling up when cranking so I have low oil pressure. I am getting over 160rpms when cranking as well. Buzz tested and cylinder 3 was a little weak but I can deal with that later. I cant get it to start. I have fuel pressure, I have low oil pressure, I have new hpop and new orings on injectors. All sensors are new with new pigtails. Im down to a wiring problem or a pcm/idm. I ran it for codes and came up with the following laundry list of codes. If I clear them. They all immediately come back. The voltage keeps going low from cranking as well but ive been cranking at 12.8 volts when tested with digital multi meter. Any help is appreciated
Just to make sure any new advice that comes along to aid you, here are a few links showing the history of advice and ideas that some have come up with. I am posting these in an effort to find a solution at a quick pace for you instead of simply repeating ourselves and others which is only a waste of time. I sincerely hope you find a solution soon and I don't personally have any advice for you other than I too think you have a "wiring or PCM" problem. The issue is that I "think" you are using some of the wiring harness from the 2008 cab, which from what I gather is a big no no. I could be wrong on this though and you are using 100% of the 7.3L harness, I just don't remember at this point.

I would venture to guess that you mixed up the plugs between the IPR and the EBPV in the turbo pedestal. They are the same type of plug and switching them will cause the result you described.
In addition, I realize the thread linked below has nearly 225 responses, but in there are some great information bits on the 5v reference including wiring diagrams and how they may affect the system.
sounds like you have put a lot of effort in this to just up and quit!
There is no doubt in my mind as you could see the light at the end of the tunnel, you missed something, ground, plugged something into the wrong place, didn't plug something in? GOnna have to walk back through with your checklist and breath!
Seriously good luck!
GREAT thread title! Gets people reading. I tell my boss, son, the same thing every Friday. He hires me back every Monday morning though! All I can say is never quit, these trucks are worth it!
I have not dead headed the pump yet but I did put a gauge in the resevoir for low oil pressure and in the icp port. Im getting no pressure at all on the high pressure side. I am getting 50psi when cranking on the low pressure side after about 8 seconds of cranking. I exchanged the fuel pump and I do have fuel pressure as well.
I have nothing helpful to offer. Keep at it. As others have stated the problem (based on codes) is electrical in nature. Did you keep the 2008 front end? Would love some pics....
Just like the questions noted above in this thread, which is quickly turning into thread 7 in the list for your next thread, you seem to omit some of the answers to questions or suggestions that you don't understand or don't care to investigate. This is why you are not getting any further help than what you have already received over the past few months.
No one knows other than you what is happening with your 7.3L and repeatedly posting a screen shot of the DTC's you have pulled does nothing except bring your thread to the top of the list. If you are going to quit, then quit... If you are going to pursue a fix action and a running 7.3L engine, you MUST get on the ball and answer questions. You MUST do the work regarding what the Ford Service Manual is telling you, what the FTE'rs are telling you and what the engine is telling you. People are frustrated, just as you are.
So, here we go again...
Looking at your DTC's and what you have said is "100% of the engine and trans wiring is 7.3. No modifications." You have some serious problems with major systems in getting that engine running. The diagram above is posted for your viewing pleasure and to see how everything is connected together. Maybe this will make it easier for you to investigate.
Did you check PCM pins 90 & 91 for 4v - 6v DC as described in the attached 5v reference pinpoint test?
DTC 1670 can be a ghost DTC sometimes, but is associated with the EF signal and IDM. I have attached the pinpoint test for that DTC to this post...
P0603 should go away after a few drive cycles.
P0475 is associated with the EBPV, but should not cause the engine to not start.
What does the GEM look like, is it clean or corroded?
You have to address the questions that have been asked and give detailed answers or there is no hope to get this 7.3L running. If you identify a PCM or IDM problem, you can get some reliable help from https://www.dieseltechchatt.com/prod...12361158393919
If you would like for me to **** off and stop bothering you, repeating myself, posting Ford Service Manual pinpoint tests and just plain get out of your way, I will do that if you just say so. I am attempting to help you as I have for months in the past, but I will simply go away if you are tired of reading my thoughts, suggestions and what Ford says you should do for the DTC's you have logged.

I thought this one looked familiar, And back when i read what he was going to do i remember thinking that's a hell of a project, there are going to be many issues to be worked out in the end!
But Sous you are correct If he is really looking for help , this is the place, But he has to play along and help us help him! No Jerry Maguire pun intended!

I have done every step with the exceptioncof the referenfe voltage check which i will. Ive been giving the answers to anything that was out of spec. I intend on checking pin outs for ipr and icp. I have 2 fully charged batteries and the p1670 keeps coming back. I should have done the air test through ipr tool prior to putting any oil in resevoir but I didn't. Im going to do that just to verify that the injectors are seated properly. Im trying to find a pcm or idm I could borrow as well. If those don't do it I'll keep going
