I've been searching for a week and cant find an answer. I am swapping a 81zxt motor into a 83 zx. I have followed the writeups and everything seems to be right except I have no spark. I have fuel. I have a switched 12v to the ignitor. I dont think im getting a signal from the yellow/white signal wire from the ecu to the ignitor. Im not sure what the signal is supposed to look like but I only have a multimeter and I do get something like .3 -.4v while cranking. I have 12v and ground and 2 signals from the CAS. The green light on the ecu is on with the key in the on position and goes off while cranking.
So i guess my question is what should the signal to the ignitor be?
The swap was running in the donor car so I dont think its a hardware problem. But maybe the ignitor could have gotten damaged? I have switched the coil with the stock NA coil and it didnt help.
