I'm feeling as though I may be a complete moron. Spark signal is going to the coil-connectors, no spark coming out. No idea how this is happening.

Coil has 12v? Sending it to the correct pin? Good ground?

11.75volts at top coil-on-plug connector pin. Battery is a tad weak at the moment.

From looking at the mazda diagram, Power then ground, then signal, is the pin order for the 01+ connectors, descending from the top.



I can watch the trigger signal when I probe the connector with my multimeter. Yet, no spark output. I've tried 4 different coils.

A diagram I have says A = 12V, B = ground, C = trigger.

Edit: Looks like we have the same diagram.

So, if we both agree the wiring is going to the right places, where does that leave my spark output?


Lots of dead coilpacks?

So I fired up the old tunerstudio.


I have pulse width at the injectors. YAY!


I would imagine that means I have spark output now.

Perhaps my weak battery couldn't properly fire the coils? I have fuel for sure now, I can smell the flooded cylinders.

The plot thickens. Fuel is there.


However my timing light and multimeter both confirm no spark current through the coil wires. Would having signal and ground reversed have cooked the coils?


The main screen now says: Ready/Cranking/RPM Sync/Full rpm sync.

However, "SPK1/2" does not turn green. If it were to be green; Is this the idiot light for "yes, you have spark"?

SPK1/2 is to show if you are using spark table 1 or 2.

Why not try to fire it up with the 94 coils so see if everything up to the coils is ok?

IT RUNS!!!!!


You're awesome Rev.



Kinda idling high, rich, wants to die if I give it gas, but I haven't set the timing yet either. I'll keep you updated.

Good to know man!

hey sorry to revive and old thread but did you need to add the CAS back but did you just plug back the old ignition from the 94?
