My plugs are not sparking. I'm using a tuned s14 ecu on an s13 sr20det. The ecu has started the car before, then fried later on due to bad mafs wiring. I had the ecu rebuilt and got nothing. I also replaced the ignitor chip with a Z32 one and is wired correctly. I've tried grounding the plugs and got nothing. Last, I used a test light and got power before the chip and got power but the other side with the ground got power while the motor was cranking. What could be wrong??

Ummm, with all that changing and cross chassis usage, my first guess is that almost everything could be wrong. Its easy to guess on a stock SR with the right ECU, right igniter chip, and right MAFS. But everytime you add a new part, it just multiplies the possibilities. My guess is either incorrect wiring, or a blown part (ECU, Ig chip, MAFS, wiring).

The s14 ecu has been rebuilt and has power ( It runs my SAFC II at least) I have driven the car before my s13 ecu fried because of the MAFS wiring which is fixed now, the z32 ignitor is working.
