Little question here. Just swapped a Blacktop (without VCT) sr20det in my friends S13. I soldered all the wires myself and followed this guide, HERE (http://www.frsport.com/SR20DET-Swap-Engine-Harness-Wiring-Diagram-Guide-SR-SR20_t_26.html).

Im getting fuel and the spark signal, but no spark. The coil pack uses a three pin harness. Im getting +12v key on, +12v signal, and nothing on the third wire. The wire color is black on coil one, and red for coil two through four. I believe its a grounding issue and I have checked all my grounding straps, and everything looks good. I could be wrong about that wire being ground, but thats why im asking.

Any help would be great, thanks.
