Thanks Neilly, I see. Today I replaced the injector o rings and washers, cleaned that area. No difference. When I finally got it to start same issue. Ran for a little while, rough idle, smoke, and the shut off as if run out of fuel. The fuel preassure seem good before and after regulator. No leak at regulator. When the car shuts off, the fuel pump is quiet too... I don't remember how it should be. Should it shut off at stall or continue to run or do I have an electrical issue where the fuel pump is shut off after initial pumping? Now at home I am thinking maybe I have an air intake blockage. That could produce the smoke and the stall right? Have to take off the inlet hose again to check to that... Can the regulator be damaged in a way that it could produce issues like this, it's not leaking or showing reduced preassure.
