HELP! Adjusted IACV the wrong way.

Ive searched around and couldnt really find much on this specifically. finally finishing up my s20det swap. is an s13 type x with j4 ecu going into an s14. i decided to adjust the idle screw without going into idle adjust mode and as soon as i gave throttle the car died. tried starting it up and noticed my fuel pump is not priming. could these 2 be related in anyway? i hard wired the pump and its working fine. my ecu isnt giving any power to the relay. and the car started perfectly the past 2 days. any one out there that would be able to shine some light?

Turning the IACV screw will not affect power to fuel
Pump relay.

^ agreed they don't affect each other.

Oddly enough tho I have had a couple friends have issues with the fuel pump not priming with s13 sr's into s14's. I don't have an answer for you but a search and a peak thru the wiring diagrams for your fuel system should lead you in the right direction.
