[fc nut]

i have an 84 gsl se with an 87 n/a engine running on se injectors,ecu. the car ran awesome before the coolant seal went and lost compression. i rebuilt it and i'm running the fc leading coil. the issue is,only the leading coil isn't sparking. i've checked all grounds,voltage at the ecu and coil. i switched out the fc coil for the stock one and still no fire. the plugs,wires,cap,rotor are good as well. the magnetic pickup gap is in spec,cleaned the contacts and switched out the leading igniter. it cranks,the trailing is firing. i've checked all wiring for breaks and corrosion, i've been racking my brain for a couple of days now on what it could be. i'm gonna try something else. i need fresh input on this.
