hi im having a some problem with the ignition system but first the cars history the car is a 88 na auto that when i picked it up was already converted to a 5 speed the engine is a engine ive been building for a few years now its a 87 7mgte the harness is also from a 87
the problem is out of the 3 coils im only getting constant strong spark on 1 of them the other 2 i get almost no spark (1 spark per every 30-40 revolutions of the cps if that)
i have test the cps (all 3 cps i have tested good) even swapped for a known working 1 didnt help
i checked all the wiring for the cps to the ecu no shorts not cuts its all good
i tested the coils all 9 of my coils tested good (i have 3 sets)
i tested the wiring from the coils to the igniter no shorts or cuts all good
i tested the wiring from the ignitor to the ecu no shorts or cuts all good (the ignitor is off of a car that was running a week ago)
i tested the ignitor per tsrm insturctions tested good
i have 12v to all coils
i have 12v to the ignitor
i even swapped the ecu twice no diffrenece
i even did the ground mod on the ignitor no diffrenece
i have taken the coils off of the mount and plugged each 1 into a diffrenet plug all coils have strong and constant spark on the same plug and almost no spark on the other 2 plugs
i dont know what else to do ive checked all the grounds and everything i can think of my cps is good my ignitor is good and my coils are good but i only get spark on the 2-5 coil and almost no spark on 1-6 and 3-4 coil any any any help at all would be great
