I finally finished piecing my integra back together and now im trying to get the tming straight. For some reason i cant get the timing light to turn on or blink. I have power and ground to the light and I also clamped the #1 spark plug wire. The engine idles fine and I tried the clamp on all of the wires to see if maybe the #1 wasnt getting spark and still no llight. I also tired a different timing light with the same results. It doesnt make sense to me why its not lighting up??? Also I have an Ls/vtec; are the gsr and ls crank pulleys interchangeable? Are the white and red markings located at the same spots on both crank pulleys? Im stumped right now so any help would be greatly appreciated.
