Trying to finish the swap im running a wiring specialties harness so i know the wiring is right....ive swaped my coils to my brother rb25 there fine...swaped ignitors there fine, im running a n60 maf so i cant swap those with him nor can i swap ecu's. I pulled out the cas sensor turned the key on and rotated it i hear the injectors clicking but nothing from the coils...keep in mind ive tryed my coils and ignitor on my brothers rb25 and his car ran perfect. Ecu bad maybe? if so i was sold the wrong maf and a bad ecu and im out of 350

I think the s1 rb20 uses a j60 maf?

it does but ive been told that the n60 will work fine if wired up...today i tested the coil harness and the pink wires are staying hot which is not right? i dont believe but there suppose to ground out everytime the car turns over and that wasnt happening...then i checked at the ignitor and there were pulsing as i turned the car over...i took apart the harness and have two grounds or black wires? one coming from the ignitor side and one coming from the other plug on the coilpack harness they where tied together as if being tampered with...well every rb harness i see on has one wire coming out the harness for the coilpack ground.
