89 XJS cranks but won't start

Need some help. I have a 89 XJS that cranks but won't start. Not getting spark form either coil. Car had electrical short and fire between the radiator and the ignition coils. Replaced wiring and found one blown coil (left bank). Replaced the coil and car was running rough with limited power. I checked the cap and cleand the plugs all is good. I noticed the drivers side cat was cherry red and the car stalled. I let it cool down and still no spark. I checked the fuses (right side under the dash) all are good.
