At the trailing coil there is a four wire plug which has a Blue/Yellow wire. W/key to on and the engine turned over by hand this wire should have 5 volts and then briefly 0 volts in a repetitive, repeated manner. This signal comes from the ECU to fire the coil. The Brown/Yellow wire should have about 4.4 volts w/key to on and 2.2 volts when idling. The Blue/Red wire should have less than 2 volts when idling. And the coil/igniter receives its ground by being mounted to the fender, so make sure this contact is both clean and secure.

Satch I'm going to make sure I get the correct volts when I get a chance to get a day off of work and the contact was cleaned before I put the new mounting bracket on

No spark in trailing pack and no fuel priming
I have an 88 n/a rx7 with a jspec T2 swap i just put in i am also using the n/a harness and i fixed alot of issues with it and now im on the last one that i cant figure out my trailing coil pack is not firing like its supposed ot it only fires once in a while and ive changed the coil pack and the bracket its on(original was broken) and not only that my fuel pump doesnt prime it only does it when i open the flap on the map sensor some guy my friend talked to said he know exactly what the issue is and an ez fix but i tried talking to the dude and he isnt talking but im thinking it could be something with the wiring and its not a ground ive checked and cleaned any possible grounds this is my 3rd time posting this hoping somebody can give me some help my rx been down for the past 4 months cause of this issue

im having an issue with the leading coil pack, i have power with the black/white possibly yellow wire, but theres another wire i think its was green with a stripe that has no power, the trailing coil pack has power coming from both of these wires, my trailing coil pack gives spark, my leading gives no spark.... ideas?
