79 300 no run?

gas is yes, i guess i have to check for spark again because its not firing while cranking, it did have spark, could i have fried the coil by jumping power right to it??
Possibly , if it runs/sparks while cranking it could be ballast resistor . Sound like your altenator was bad originally , with the lights going dim before losing all power . Check alt and battery and voltage regulator , and the ground to ECU
