MULES Rebuild process

Well I have almost finished my engine rebuild. Its been a long process. I am getting burnt out on this project as I have many others. Needing some help on getting my rebuild started.

Heres what I did:

Purchased a truck through a private seller.

Found out I Needed new pistons due to glow plug damaging pistons+Cylinder.

Had a machine shop do a long block with MAHL pistons.

I started with a MAHL Head gasket
ARP Head studs
New glow plugs
Rebuilt injectors by Rosewood
Most parts bought through RiffRaff
Converted OBS Harness to SD harness (from 4 connections to valve cover, to 2)
Terminator 500 HPOP
Larger HPOP Resivror
New LPOP
Fluidamper Harmonic balancer
Water Pump
New Oil Cooler
All new sensors. I mean ALL new sensors
Rebuilt turbo
New GPR( to be honest I connected the GPR backwards, and fried my passenger side glow plug wires. Im in the process of repairing this. I am worried this may have effected the PCM in some way?)
New fuel pump
Alternator
Power steering pump
Vaccum pump,
exhaust up pipes(upgrade)
Of course all new gaskets.

1995 ford F-350 7.3 Manual 4x4 Crew Cab. 230k Miles

It has fuel in the fuel bowl, The HPOP is full of oil. I turned it over a number of times this weekend. Waiting for batteries to charge again. still no start

Looking for suggestions on the next step, Though this may take longer than it could, as work is starting to pick up. Getting really busy, Will reply as soon as I am able.

A side note: Connected my CTS Edge for specs. The CTS Stays on without key in ignition, and does not read any data when turning over. Not sure if this is correct, But I would think it would read Something when cranking.

Photos out of date, I will get more current pictures tomorrow

Wait to start light working? Not to be an ***, but you're sure the single plug SD wires are connected right? How much cranking have you done?

When I built my motor I filled the oil galleys in the heads with oil after I put the injectors in. Then when I went to start it I left the glow plugs out and cranked it over till oil pressure built up good on the rest of the motor. Then installed the glow plugs.
Even then it will take some cranking over to get everything built up as far as fuel and oil to the injectors.
Disclaimer inserted here!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!
Now This is not for everyone but I unhook the GP relay and use a small amount of starting fluid By getting the motor spinning and shoot a SMALL AMOUNT of it to get it started and just spray a LITE MIST into the intake just enough to keep it at a idle till the can runs out or until it picks everything up and will idle on its own. BUT this is what I do and like I said its not for everyone!!
It just saves a lot of time cranking it over trying to get it pumped up and saves the starter and batteries
DON'T DO THIS IF YOUR NOT COMFORTABLE WITH STARTING FLUID!!

i am pretty sure they are. Even if they were not shouldn't it at least sound like it wants to start? Yes wait to start light is on. Cranking time?? Maybe a total of 2 or 3 minuts over the course of the day

From my understanding a few years ago, the GPR cant be hooked up backwards. The two small wires and the two big wires just need to be on the correct posts, which is easy to do. Someone will correct me if I am wrong though.

I think it will take way more cranking than that to fire up. If all the fuel and oil galleys were dry

Hrmm, that seems like a lot of cranking to me..... But I will continue to try.

any Idea why my Edge Insight CTS Monitor is not reading ANY data while turning over? I would think this should read some kind of data.....

Have you checked the hpop level after cranking and did you check the fuel pressure while cranking?

Did it work in this truck before the rebuild, or have you ever gotten it to communicate with an OBS PSD?

Does it read anything KOEO, NOT cranking?

I tried two different devices. No readings from either. Cranking or no cranking this is what it reads. See below and no I have not ever hooked anything up to this truck. Though it should be comparable no???

That won't communicate with a pre-96 unless you have a 96 or newer PCM. They don't work with 95s.
