You need to power the igniter harness as well as the ECU (which powers the sensors). The igniter harness is the 6-pin, grey plug that hooks up behind the valve cover... the blue with red stripe wire gets a 10A fused, relay'd, 12V+. If you need more help, PM me and I'll give you the SR20 pinout I made for my standalone harness.

I ran a 12v switched power to the coil pack harness. Now I am getting power all the to the coilpack but still no spark. I have basically run everything that would normally get power in the acc position to a switched distribution block. To start the car I flip this switch and then use the push button starter that is installed. We now know that the coil pack harness is getting power. The other pins hooked to the switched power are: pin 4 eccs relay, pin 36 start signal, pin 38 eccs power, pin 46 eccs backup power, pin 47 eccs power, also getting 12v switched power are the ignition power, o2 power, and iac power. Is this all correct? does anything else need switched power? Please help. Thanks,

How much signal should I have coming out of the ecu going into the ignitor. My multimeter was showing a small change for 3 of the cylinders but nithing for the 4th. The readings were all around .24 volts. Is that right? Plugged ecu side back in and checked output to coilpacks side and did not get any reading on multimeter. Ignitor does not recieve power from somewhere does it? Thanks,
