just a couple of questions

[yogart900]

hey I'm new to this forum I have a 1990 240sx with the ca18det. I just got a couple of questions. So i just got finished installing my ca and it wont start now. it has compression and fuel but no spark. i did the continuity test and the coil packs and there all good. i thought it was my igniter because there was the voltage from the 4 pin plug but when i plug my igniter in no voltage comes out the 5 pin plug side. so i bought another igniter and it does the same thing. so what other things should i look at? how do i test the cas? would my car still crank if i forgot to solder a main ignition wire? Thanks any help would be appreciated.
