1999 7.3 PSD No Start

Hi All, New to this forum, and could really use a bit of your expertise.
I have an early 1999 7.3 121,000 miles on it, all stock.
Here are the issues. The truck will crank, and only start if I open the fuel drain valve on the bowl, it will then start but idles super rough, and has nothing when you press the pedal. Will not idle at more than 500 on the tach. If I open the drain valve again, it will smooth out the idle, but still no RPMS. And of course makes a mess! So here is what I have changed/checked/done so far, and still have the same issues.
New Valve Cover Gaskets and wiring harnesses
New CPS
Reman IDM
New fuel pump
fuel tank is clean
New EBP sensor and tube(was blocked solid and had a crack)
New batteries
Gauge on HPOP, was reading 1700 psi at cranking, would go up to about 2700 when running then drop to around 750PSI.
Fuel pressure at head is 80psi.
Took apart IPR and cleaned it up, all seemed fine, Orings all in good shape on it, no oil in ICP plug, but wondering if either might be the problem.
Currently putting new o-rings on the injectors.
No smoke at cranking, and no smoke when it is "running".
OBDII scanner KOEO
showing codes P1293 and 1294 and P1272
P0470
And KOER
P1690
P0381
P0603

Havent tried the codes since replacing the EBP sensor and tube. All fuses and relays have been checked, also checked all the wires with a meter per one of the other posts here and all wires between the Valve Cover Gaskets and the IDM check out perfectly.
SO any ideas where to start next? Will know by Monday if new O-rings on the injectors make a difference, but getting really skeptical at this point. Am I missing something to Check? Or possible to get a bad IDM. Ordered from the place in Florida, will have to look up the name.
History on the truck: Know previous owner put bad fuel in it, and supposedly tore everything apart and cleaned out the injectors, tank, lines, etc. But hadn't replaced the fuel pump, which I did. Also has "AB" injectors in all except #3 and # 8 these are AD injectors. Can this make a difference or cause a problem?
So debating if getting the AE program can help narrow this down, or if my PCM is bad, IPR, etc. Hate to spend much more money as the ones left are expensive until I can pinpoint which one is the problem for sure. Any ideas on what tests to perform from here? Any and all help is GREATLY appreciated.

take your fuel return line off, and run a separate hose either back to the tank, or into a 5 gallon pail. Start the truck, and see how it runs. if it runs properly, you have a restriction in the return line, and should change it.

All lines are clear on the fuel, the bed is off so took lines off the tank, made sure tank was clean and all lines clear.
Put the new O-rings on the injectors, and now truck will start, but now it takes 8 to 10 seconds of cranking to build the oil pressure up high enough to start. Once the pressure hits 500 psi, it will fire. Smoking a lot of smoke that smells like raw diesel. So now trying to figure out why the crank time is so long to build the oil pressure....
