Fuel but no spark.

Auto to manual conversion with the park/neutral switch jumpered.

Getting fuel just no spark.

Thought ignitor chip (Z32) was bad but tried my extra one and even robbed one off my Z that I know is good. Still no spark.

So I checked voltage, and ground on all 4 coilpack harnesses and it checks out. Also continuity from coilpack harness ground and ignitor chip.

TPS, CAS, Ignitor chip, MAF, fuses and relays all good.

Took CAS out and spun by hand and could hear EGI Relay click, all 4 injectors click, and hear ignitor clicking / buzzing but no spark. Had a coil pack out of valvecover with spark plug connected.

If I try to start car and have voltmeter probe in far right coilpack harness connector (signal wire) I'm not seeing any voltage or fluctuation in voltage. Doesnt the CAS send a signal in voltage to the coilpacks telling them to fire?

Havent checked with a spare coilpack. Hoping to find one I can borrow locally. Dont see how all four coilpacks would be bad though.

Anything I'm overlooking here other than checking a coilpack I know is good?
