    try it. I have seen how people start engine after injectors change. hand priming and starting fluid for 1-2 minutes. after that engine runs.

    Yea. Hand priming and bleeding just isn't doing it for me. I've been trying for days. It has to be air though because I have no codes or odd issues noticeable with the engine. With the diagram, I can follow the lines but do you think priming will in fact reach the high side?

    I don't think we can prime high pressure side. I would connect DL , run starter and monitor fuel rail pressure. if it shows normal pressure value then injectors are not opening ..

    Also, I would assume that I would be getting codes if an injector wasn't opening... Let alone all six. It doesn't attempt to start. No rough idle or nothing. But like I said, I kind of ruled out injector problems because I confirmed they were getting power when I tested the harness through the DL.

    I'm saying the high pressure pump isn't a complete block. Just like high side and low side A/C system will equalize if the pump isn't running. Fuel will get past the pump up to the injectors.
