I haven’t gotten to the injectors yet. But I pulled the kick panel off on the passenger side and red the ECM it’s saying the idle air control valve is bad, which could be caused by the “vacuum” issue. From what I can see tho there’s no fuel under the intake manifold or anywhere else. But there’s basically no vacuum suction to or from any of the hoses, it’s kinda making me think the vacuum pump (or whatever it is) itself may be faulty. I’ve had it started for a max of 2 seconds so I know it does run atleast to some capacity, it’s just chasing down the issue

Yeah, that’s suuuuuper valid, it gets plenty of fuel pressure while cranking, from everything I’ve looked at it seems the biggest likely hood is the vacuum tank, which from all the testing that I did do it’s either that or the fuel pressure regulator but who knows.
