Willing to bet on "fuel pump"

Hard to start. Takes 2 or 3 times. Not imediately locking in priming pressure.(Check valve)also I think located in pump.

Just maybe the pcm?

Dies or rough idle at intersections? Not maintaining correct idle pressure. Could be a regulator also.

As far as injectors? Who knows.
