Trailing Pack not firing
 

i have an 88 n/a rx7 with a jspec T2 swap i just put in 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)...the weird part was that it only started doing this once i changed batterys the old battery i had was bad and could only jump starter to start it but need help been trying to figure this out for the last month
