SO i have power to fuel pump and it does it's thing for 5 seconds when the key is turned to run. I have power to ignition switch. The starter has power and turns the motor properly, and my noid light shows signal to injectors.
Im good to go except spark.

The coil gets power, but it shows power to both + and - and power won't come out the coil's snout. And obviously power is not present at the dizzy much less the spark plugs.

I have both the B/W wire from my NA harness and the B/W from my ignitor going to the + on the coil
I have both the BLUE NA wire and BLUE ignitor wires going to the - on the coil.

CONTINUED WITH PICS

Alright i have an idea i want to run by you guys: (This is not a pic of my engine bay)

I was thinking this little plug T connector that goes to the ignitor is the key to why i am not getting a signal from the coil to the dizzy. I think i have this plug in my car, i just don't think it is plugged into anything. because i have one of these 300zx ignitors

and i can't put that plug directly into it. SO i have mine hangin around loose and don't know if i should do something with itcan you guys make sense of this? Ideas?
82 zx -> zxt swap
i have an 82 zxt motor with all 82 zxt components (ignitor is 300zxt)

Why are you using a 300zx ignitor?

cause it was a cheaper replacement for me and plenty of guys have run it on the 280zxt and the 300zxt coil and ignitor throw crazy spark.
don't get me wrong, huge regret

So, can you hook it up?

yea its all hooked up, but the "t" connector doesn't hook up to it. Without the t connector hooked up, is that why the coil won't throw out its spark?

How do all these other guys have it hooked up? I've personally never heard of using the Z31 ignitor for the 280zxt...

i wish i knew.
you can see the "t" connector on there by the ignitor. I don't know exactly how to make that hook up to my 300zx coil in the picture... but i think that might be what is keeping the coil from getting the spark out

a connector style isnt going to stop a car from running, if you got it connected you got it connected.... it obviously wont plug straight in, but you can modify either the connector ont he car or the connector on the ignitor... your choice.

see thats the thing, the ignitor looks as is in the picture. I dont know how to hook up the 2 wires from that connector, to the 3 available wires on the ignitor.
I broke the casing off the 300zx ignitor and put circle spades on the 3 wires to hook them to +/- and ground. The t connector... no idea how to splice that.

oh jeez, i couldnt even tell there were three wires, i saw only two at first. dude, i would just get teh proper ignitor. otherwise find a write-up on zcar.com hybridz.org where people use these ignitors... but ive never heard of it either.
