alright, i have a s13 sr20det, im not getting any spark, im not getting any power to the big blue/red wire that plugs into the coilpack wiring. i been digging thru wires and the ign coil relay has 4 wires going into it. theres the blue/red, black/red, black white, and black. the black and white wire has continuity to the ecu power wire, pin 38 and has power. the black and red also has power and has continuity to the ignition signal wire, pin36. i assume the little black wire is the ground. so, i have power going into the relay in two wires, but there is no power coming out of the relay in the blue/red wire which gives power to the coilpacks. so is my relay bad?? i tried changing it with another and still got no spark, im confused.

alright, nevermind all that relay stuff, i dont even really need it. sorry about that, i didnt realize that is wasnt even really needed. got that all fixed up. so , as of right now i have constant 12v and good grounds at my coilpacks. still not getting any spark. there is 12v before the ignitor, on the ecu side. but after the ignitor im getting nothing. what should i be getting on the ignitor wires going to the coilpacks?? its a brand new z32 ignitor, definitly wired correct. i have checked the cas and it is getting between .1 and 5 volts while i rotate it, so it checked out good. the red light does still come on and stay on when i try to pull the codes from the ecu, does that mean my ecu is bad?? i thought that just meant it was in limp mode and the car should still start.
