I can't see in the pics but do you have the main PCM relay?
Also, are you trying to start on the factory ECU? Is it a JDM one or US market one?
The JDM one uses a different fuel pump relay wire to the US market one. Something to watch if you are mixing and matching parts. From memory its something like A15 and A16 so you can just move the pin on the plug across.
Don't be surprised if the injectors have frozen with dried fuel residue. I find a quick tickle with battery voltage gets them clicking again once you have fuel pressure wetting them from behind.

Made some progress yesterday got a lot of the wires marked and figured out.

Just been slowly chugging along. I'm just about done with the fuel pump wiring/relay. Waiting for my starter and a couple fuses in the mail. I'm a little confused on the stock fuel rail regulator. Considering the new external fuel pump should I also place a pressure regulator in the line or will the stock one in the fuel rail suffice?

1.) First questions is the bypass hose is just needed for smog correct? This has no effect on cooling circulation in the block right? I want to remove it if its not hindering anything. Also from the diagrams I have looked at the other tube coming out of the thermostat (not radiator hose the one without a hose) is the heater hose. I'm not going to be running AC or heater so I can plug that up?
You are right on the other (The one circled), it is a heater hose. For that one, I just connected a short hose between that pump housing and the return (the lowest hose in the picture below)
2.) On the back I have three hoses in question. First is the one on the rear of the intake, which would be the vacuum for the brake booster so I can plug that for the time being. Below that I'm not sure what significance that hose has can it be plugged? the bottom one is another heater hose so I can plug that sucker too?
now for some wiring fun. This is what I was able to snag with the engine. Its the ECM with 2 out of the 3 connectors. My question is whats the third? Also the blue one... no clue what thats for yet. I'm still trying to find good wiring schematics, however I just started my search so if anyone can send me some good information regarding the ECM and what I need to get this started that be great.
Thanks for any help and I will be posting quite frequently as my progress continues.
